Temperature Intolerance caused by Adrenal Fatigue
Intolerance to heat, temperature, and sunlight is a very frequent complaint of people with advanced adrenal fatigue. http://www.drlam.com/blog/adrenal-fatigue-symptoms-temperature-intolerance/16839/ This is Dr. Lam, founder of DrLam.com. Here we will talk about why, why is it that most people in adrenal fatigue cannot handle the sun. They go out for a few minutes, let's say they do some gardening, they go on a road trip they can crash. They have difficulty taking a bath, for example, because the heat from the bath water can crash them instead of relaxing them. This is very common, we see that a lot. Now, let's back up a little bit. A body that is in adrenal fatigue has compromised feedback loops in not only the hormones but temperature regulation. Not only is this because of for example salt deprivation, or imbalances; electrolyte irregulations, fluid that is not properly given to the body or retained by the body, all these leads to temperature control. One of the classic things you will find is that people will report the inability to go into any of kind of sauna, they cannot sunbathe for example we talked about this earlier. They all point to a thermostat that is in the body that is somewhat not working very well. It is almost like you have a thermostat in your home when it hits a certain temperature then the body regulates on its own. If the body gets too heated up the body will open up the pores of the skin and then perspiration will happen, and then the temperature will come down. Likewise, if you are feeling cold, then the body will constrict the skin, and the fluids that are in the body will get heated up, and the temperature will rise. In adrenal fatigue this mechanism is somewhat compromised, so, if you put the person into a sauna, or in the bathtub, not only will it not relax the person it actually crashes the person because it is just the regulation is broken. So the body can for example in the sense of heat they can have evasive dilatation but they don't have evasive constriction, the compensatory mechanism so the blood gets pooled in the rest of the body and then you don't have enough in the brain and you can have an adrenal crash for example. There are many mechanisms that go in but overall picture that you have to understand is that most people in advanced adrenal fatigue, I'm talking about advanced adrenal fatigue not regular adrenal fatigue, have temperature intolerance, and it is quite normal. The degree they are able to tolerate the temperature usually tells you the degree of advancement. In fact, what happens is that as people get better their ability to tolerate temperature is improved. So, at first they may be able to go in the sun for five minutes, and as they get better they can go out in the sun for a little longer, and a lot longer, and a little longer. So that is of course provided if they are improving in the right direction. If they are simply improving adrenal fatigue by energy alone but not other things then actually there may not be any significant change in their temperature regulation because improving energy alone is not the only offset for adrenal fatigue, you can be masking the underlying problem. So this can be quite confusing we deal with a lot of people like this when they are in advanced stages, it is not something to be worried about but it is not something to be taken for granted, it has to be put in the right perspective, and do the right thing is to allow the body to recoup on its own and then you will not be held hostage by these temperature dysregulations. Important symptom, no question about it, but it has to be put in the right perspective.

What causes a girl to experience excessive body heat? - Dr. Sanjay Gupta
It is especially important to know the age of the patient, especially when it involves a female to understand the disease per se or the etiopathogenesis of the disease. Is a girl having problem with excessive heat in the body. My first inference should be whether there is a female who is turning into puberty. So whether it is an adolescent phase which is leading to this hormonal changes or whether the person is facing on or any other of the problems, like already there is a metabolic rate which is very high. Metabolic rate can determine the patient’s heat or the patient’s temperature. The body temperature when you discuss it as heat, you can interpret it as heat, it can be fever or in terms of disease. Fever can be part and parcel of any other disease. But when you rule out a fever, then it has to be something to do with metabolism. It has something to do with hormones or hormonal changes or those heat can happen in cycles and then probably the girl is experiencing menstruation. So it is important too know all these factors, then we take the medical history of a girl who is experiencing excessive heat. These changes and fluctuations at the age of person and nth underlying problem, all this comes into play. And if all this is ruled out, then probably we can look at the atmospheric conditions, which the patient adapts to the atmospheric conditions. So those will sum up our approach to the girl who is facing excessive heat.
What is Heat Tracing? - A Galco TV Tech Tip
Heat tracing is a system used to maintain the temperature of pipes, vessels and surfaces. In heat tracing, an electrical heating element is fitting in physical contact along a length of pipe or across a surface. Heat generated by the element maintains the temperature of the surface. Typically, the pipe or surface is covered with insulation to retain heat loss. A robust heat tracing system often includes a thermostat, monitor and controller so that end users can track and adjust the temperature of the heated surface.

what's the causes of sweating?/ Thermo heat regulation/ Hyperhidrosis
When your body starts to heat up, whether it's because of exercise, work, or outside temperature, your brain reacts by releasing sweat from the more than 2.5 million eccrine glands spread out across nearly all of your body, pouring liquid through pores to lower your body temperature. But when sweat simply drips off you and hits the floor, it can't lower your body temperature. To reap the cooling effect of sweat, though, that salty liquid must evaporate off the skin and turn into a gas, says William Byrnes, a sweat expert at the University of Colorado.Cooling sweat isn't the only type of sweat. Humans also have apocrine glands, primarily in the armpit and groin. These glands also act as scent glands—in animals, musky sweat can help attract both males and females, Byrnes says. The milky fluid from this sweat contains more nutrients, which makes it more attractive to the bacteria Staphylococcus hominis that largely resides in the armpit and groin. When these bacteria and sweat interact, we get body odor. Like eccrine glands, these glands get activated during exercise, but apocrine glands also come alive when we get emotional, nervous, or excited. That means the most smell-inducing (and white tee-ruining) activities may not be running up a hill or playing basketball, but rather going in for a first kiss or giving an all-staff presentation. Sweat isn't triggered by heart rate or movement, but by receptors in the hypothalamus area of the brain. Individuals living in hot and humid environments will adapt to the weather, just as people aerobically trained will sweat more and sooner. The body welcomes "adaptions that help us with heat regulation," Byrnes explains. Because the stink of sweat doesn't come from the odorless, colorless liquid the body produces in an effort to cool the skin, but rather from contact with bacteria present on the body, we have to combat it from all angles. With this bacteria concentrated in the armpit, applying a powerful deodorant to that specific area, instead of rubbing it all over, proves the most effective way to combat B.O.

What is HEAT SINK? What does HEAT SINK mean? HEAT SINK meaning, definition & explanation
What is HEAT SINK? What does HEAT SINK mean? HEAT SINK meaning - HEAT SINK definition - HEAT SINK explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature at optimal levels. In computers, heat sinks are used to cool central processing units or graphics processors. Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as lasers and light emitting diodes (LEDs), where the heat dissipation ability of the component itself is insufficient to moderate its temperature. A heat sink is designed to maximize its surface area in contact with the cooling medium surrounding it, such as the air. Air velocity, choice of material, protrusion design and surface treatment are factors that affect the performance of a heat sink. Heat sink attachment methods and thermal interface materials also affect the die temperature of the integrated circuit. Thermal adhesive or thermal grease improve the heat sink's performance by filling air gaps between the heat sink and the heat spreader on the device. A heat sink is usually made out of copper and/or aluminium. Copper is used because it has many desirable properties for thermally efficient and durable heat exchangers. First and foremost, copper is an excellent conductor of heat. This means that copper's high thermal conductivity allows heat to pass through it quickly. Aluminum is used in applications where weight is a big concern. A heat sink transfers thermal energy from a higher temperature device to a lower temperature fluid medium. The fluid medium is frequently air, but can also be water, refrigerants or oil. If the fluid medium is water, the heat sink is frequently called a cold plate. In thermodynamics a heat sink is a heat reservoir that can absorb an arbitrary amount of heat without significantly changing temperature. Practical heat sinks for electronic devices must have a temperature higher than the surroundings to transfer heat by convection, radiation, and conduction. The power supplies of electronics are not 100% efficient, so extra heat is produced that may be detrimental to the function of the device. As such, a heat sink is included in the design to disperse heat to improve efficient energy use.

what is heat in hindi | explain heat in hindi | define heat in thermodynamics in hindi
Easy engineer app download here https://goo.gl/TpXaS7 Heat is the amount of energy flowing from one body of matter to another spontaneously due to their temperature difference, or by any means other than through work or the transfer of matter. The transfer can be by contact between the source and the destination body, as in conduction; or by radiation between remote bodies; or by way of an intermediate fluid body, as in convective circulation; or by a combination of these. In thermodynamics, heat is often contrasted with work: heat applies to individual particles (such as atoms or molecules), work applies to objects (or a system as a whole). Heat involves stochastic (or random) motion equally distributed among all degrees of freedom, while work is directional, confined to one or more specific degrees of freedom. Since heat (like work) represents a quantity of energy being transferred between two bodies by certain processes, neither body "has" a definite amount of heat (much like a body in itself doesn't "have" work); in contrast, a body indeed has properties (state functions) such as temperature and internal energy. Thus, energy exchanged as heat during a given process changes the (internal) energy of each body by equal and opposite amounts. The sign of the quantity of heat can indicate the direction of the transfer, for example from system A to system B; negation indicates energy flowing in the opposite direction. Although heat flows spontaneously from a hotter body to a cooler one, it is possible to construct a heat pump or refrigeration system that does work to increase the difference in temperature between two systems. In contrast, a heat engine reduces an existing temperature difference to do work on another system. Heat is a consequence of the microscopic motion of particles. When heat is transferred between two objects or systems, the energy of the object or system's particles increases. As this occurs, the arrangement between particles becomes more and more disordered. In other words, heat is related to the concept of entropy. Historically, many energy units for measurement of heat have been used. The standards-based unit in the International System of Units (SI) is the joule (J). Heat is measured by its effect on the states of interacting bodies, for example, by the amount of ice melted or a change in temperature. The quantification of heat via the temperature change of a body is called calorimetry, and is widely used in practice. In calorimetry, sensible heat is defined with respect to a specific chosen state variable of the system, such as pressure or volume. Sensible heat causes a change of the temperature of the system while leaving the chosen state variable unchanged. Heat transfer that occurs at a constant system temperature but changes the state variable is called latent heat with respect to the variable. For infinitesimal changes, the total incremental heat transfer is then the sum of the latent and sensible heat.

How to Balance Heating System Radiators - Plumbing Tips
AMAZON TOOL SHOP HERE: https://www.amazon.co.uk/shop/plumberparts ***VISIT OUR SPONSORS*** http://www.traderadiators.com | http://www.wilo.co.uk | http://www.adey.com A brief video on how to balance heating system radiators. Includes lockshield positions and TRV's. Plumbing Tips - diy. For more information visit our website at http://www.plumberparts.co.uk Today I'm going to tell you about balancing heating systems, why you should do it, the symptoms that mean you might have to do it, and how to do it. Firstly let's have a look at the general layout of a heating system. We'll have a look at it schematically because that will help you understand why balancing a heating system is so important. Let's say we have two storeys; Level 1 and ground with the boiler at the bottom. Coming out of the boiler we have a pump that goes up, through a diverter valve, through some radiators upstairs and then downstairs with common returns going back to the boiler. OK? So you've got radiators here. The first reason that a heating system should be balanced is even if there's a pump on a heating system hot water naturally likes to gravitate up and stay upstairs and then make it's quick route back to the boiler. So what you often find is the radiators upstairs are getting loads of heat and the ones downstairs are still really quite cool so what you should do is go to the lockshields on the radiators upstairs close them, then open them at about a quarter of a turn. You won't notice any difference in the radiator's heat capacity or not but you will notice that more hot water flow is diverted to the radiators downstairs. Now, you go downstairs, make sure that the radiators are open and that means the heating system should be balanced. Another reason you should balance a heating system is, say, this radiator is getting hot, that one's getting hot, and this one's getting hot, the last radiator on the line isn't getting so hot and that's because these radiators are effectively pinching the hot water flow delivered by the boiler and the pump. What you do then is remove the lockshields on these radiators here strangle those two up there down, shut them, give them a quarter of a turn. This one here bring that down, ok, and shut them and give them a quarter of a turn. We also do a video on why one radiator isn't getting hot, 'cos it can be more than one reason, not just the fact that the heating system isn't balanced. Now that is a brief idea of how you balance a system and why. Now let's take a quick look at the lockshield, how to shut it and also to give it a quarter turn nip to make sure that it is all balanced. So here we are, upstairs, ok. Now the radiators up here get really hot so let's have a look at how we're going to strangle this one down and balance this system. So here we are with our first upstairs radiator. There's four on this system upstairs and do the same thing to each one. Here's the lockshield end, not the TRV end. Pop the lockshield cap off and close it by turning it anti clockwise. Once it's fully closed just slack it back a quarter of a turn. Do that to each radiator upstairs and you should find then that the radiator side of the heating system is balanced. Now let's look at what we can do to balance out the hot water coil on your heating cylinder if you have an indirect one. Right, so we've had a look at how to balance the radiators on the heating system. Now we're going to have a look at how to balance the hot water coil on the indirect cylinder. Alot of houses in the UK have indirect hot water coils on the cylinder. That means that hot water from the boiler is passed through a coil in the cylinder and that heats the water up. Now often these coils are 22mm in pipe size and when the valve opens up to let hot water through that coil, it pinches loads of heat from the radiators. Therefore the indirect hot water coil should also be balanced and regulated. Most plumbers installing an indirect hot water cylinder will put a flow regulating valve on the return side of the coil Let's have a look at it. So, you have your boiler, your pump and your 3-port valve, or if you've got an s-plan it will just be a 2-port valve for each side. You have all your radiators with their flows and returns. We have the flow coming up here from the boiler, goes through the valve into our hot water coil, in our cylinder and back out. It is here where we fit our flow regulating valve, on the return side of the hot water coil. That will go back into the return side of the boiler. So, to recap, we have the boiler, the pump, and our diverter valves. The radiators upstairs have been strangled down and regulated and the ones downstairs are getting a good flow of hot water. We've also strangled down the return on the indirect hot water cylinder and the whole heating system now is working properly.

√ Physiological and Structural adaptations of ectotherms and endotherms | Biology
#iitutor #Biology #Water https://www.iitutor.com In this video you will learn: Different ectothermic and endothermic adaptations. Structural and physiological adaptations for both cold and hot environments. Structural adaptation are physical features of an organism such as their shape, body, or any other structure in relation to the body that allows them to increase their chances of survival or better suit their environment. Structural adaptations that assist with temperature control include insulation such as fur, hair, feathers, insect scales and coats that enable a layer of air to be trapped to reduce the amount of heat lost. The feathers of the emu act as an insulator to reduce heat gain or loss. Blubber is another form of insulation to reduce heat loss from organisms living in water, such as the Australian fur seal. This significantly minimises heat loss. Physiological adaptations focus on the inner body functions. Metabolic activity is important for the functioning and the survival of individuals, but this activity also generates heat within the body. The rate of this activity can be altered to ensure a better chance of survival in warmer or cooler environmental conditions. Hibernation and torpor are examples where organisms lower their metabolic rate to conserve energy and, as a result, reduce the amount of metabolic heat energy that they generate within their own bodies. Hibernation is an extended period of inactivity in response to cold, where the body temperature does not drop below 30°C, but the heart rate and oxygen consumption drop considerably. Hibernation is a state of greatly reduced body activity, used to conserve food stored in the body. Some animals hibernate for part or all of the winter. The animal’s body temperature drops, its heartbeat and breathing will slow down, and it uses little energy. Examples: ants, snakes, black bears, beavers, and ground squirrels. The term aestivation is used for animals that hibernate in hot conditions. For example, the Bogong moth (Agrotis infusa) migrates to spend the summer months in caves in the Australian Alps. A state of torpor is a short-term hibernation where the body temperature drops much lower (below 30°C) mimicking the ambient temperature and the metabolism, heart rate and respiratory rate decrease, accompanied by a reduced response to external stimuli. For example the mountain pygmy possum. If the ambient temperature is high, endotherms have a physiological cooling mechanism as well—the rate of heat loss from the body can be adjusted by altering the flow of blood near the body surface. Kangaroos can release heat by their blood vessels dilating called vasodilation. This releases heat, especially in the ears as it is a thin surface and heat can easily be lost. When cool, their vessels constrict again. Endotherms eat more food than ectotherms. This higher food intake results in an increased level of metabolism, which is required to produce heat. Compared to reptiles of the same weight, mammals use at least five times more energy. There are 5 major ways animals respond to stimuli in their environment. Sweating (physiological). Sweat evaporates from the surface of the skin and it cools the animal. Shedding (structural). Shedding- animals may form thick coats of fur or feathers to insulate their body from cold weather. When it is hot, animals shed, to provide a cooling effect. Panting (physiological). Panting means to breathe heavily. This causes an increased air flow and as a result, there is an increase in evaporation from the animal’s mouth and lungs. Shivering (physiological). Shivering increases heat production. It is a natural response to a temperature drop outside the body. It increases the rate that energy is turned into heat. 5. Changing Position / Location (behavioural). By moving location, organisms can seek a cooler environment by finding shelter or shade. Can you think of different behavioural, structural or physiological adaptations that endotherms or ectotherms have to make them more suited for their environment? Endothermic and ectothermic organisms have different types of adaptations to better suit their environments. Some adaptations have an effect on the organism’s metabolism, increasing their chances of survival.

What is the best room temperature for your home? | Hometree
What temperature should a room be? What temperature should a house be? Heating your home with Hometree. This video looks at the ideal temperature for rooms in your house. Welcome to Hometree, home of the stress-free boiler installation. Find out more at www.hometree.com Perhaps you’ve been told that it’s cheaper to have your heating on all the time or you are just looking to find the best way to heat your home efficiently without wasting money. Maybe you are looking for the best temperature to set your home, to ensure you get a good night’s sleep or the best temperature for a child or a sleeping baby to be comfortable. You could be looking to be more environmentally friendly and waste less energy. Either way, you have come to the right place, as Hometree Heating Experts are on hand. How warm should my house be? The most efficient temperature for homes, even during the Winter, is a steady 18 degrees or 19 degrees Celsius. Simply reducing your thermostat or smart thermostat settings by as little as 1 degree Celsius could save you money in the long-run. ROOM TEMPERATURE **MYTH BUSTING** Turning your thermostat all the way up will not heat your home better or faster and this method, along with leaving the heating on all day, will waste a lot of energy, as well as increasing the amount you spend on energy bills. Leaving your heating on low all day is also a waste of energy and money. Hometree Gas Safe engineers know that having the right heating controls will allow you to keep your home at a comfortable temperature without wasting fuel or heat. They recommend that you get either a programmable or smart thermostat installed in your home so that you can set regular heating schedules. In your central heating system, your controls should ideally include a boiler thermostat, a timer or programmer, a room thermostat and thermostatic radiator valves (TRVs). Smart thermostats allow you to manage your heating controls remotely from your computer, tablet or smartphone which is why Hometree provides customers with a free smart thermostat with every boiler installation. Smart thermostats sophisticated features like learning your heating routine and using your location to automatically turn your heating on or off when you leave or arrive near your home. Smart thermostats help keep your home at an ambient temperature, which is the best way to keep your home warm without wasting money. These thermostats set different temperatures at different times in the day and at night, unlike a standard thermostat which sets one temperature and time for the boiler to be on or off. For instance, a feature of a smart thermostat is that it will keep your home at a median temperature between two points - so the boiler is not working really hard to keep your home at a comfortable temperature. You only need to use a little bit of gas to get from 14 to 18 degrees Celsius. ROOM TEMPERATURE **MYTH BUSTING** It uses more gas to heat your home up from 2 degrees to 18 degrees than it does to keep the home at 14 degrees overnight and kick it up to 18 when you wake up. With smart heating control systems, you can make changes remotely if your plans change – for example, if you find yourself working late or decide on a spontaneous weekend away, you can make sure your hot water and heating aren't wasting your money. Boiler Plus was a change to building regulations in April 2018 which means that all newly installed combi or combination boilers must have smart controls featuring automation and optimisation functions. This is why Hometree recommends boilers that are A-rated for efficiency and provides a free smart thermostat will every installation. At Hometree, we know that a warm home is too important for a broken boiler to get in the way. For your stress-free boiler installation, visit www.hometree.co.uk

NASA | The Ocean: A Driving Force for Weather and Climate
The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable. This animation helps to convey the importance of Earth's oceanic processes as one component of Earth's interrelated systems. This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites to measure physical oceanography parameters such as ocean currents, ocean winds, sea surface height and sea surface temperature. These measurements, in combination with atmospheric measurements such as surface air temperature, precipitation and clouds can help scientists understand the ocean's impact on weather and climate and what this means for life here on Earth. NASA satellites and their unique view from space are helping to unveil the vast... and largely unexplored.... OCEAN. NASA Earth Observing System Data and Information Systems (EOSDIS) EOSDIS is a distributed system of twelve data centers and science investigator processing systems. EOSDIS processes, archives, and distributes data from Earth observing satellites, field campaigns, airborne sensors, and related Earth science programs. These data enable the study of Earth from space to advance scientific understanding.

What is RHI- Renewable Heat Incentive
http://www.workworkltd.com/ WHAT IS RHI (RENEWABLE HEAT INCENTIVE) Renewable heat is an application of renewable energy and it refers to the renewable generation of heat, rather than electrical power (e.g. replacing a fossil fuel boiler using concentrating solar thermal to feed radiators). The RHI is the world’s first long-term financial support programme for renewable heat. HOW IT WORKS The RHI pays participants of the scheme depending on the renewable energy they produce and use to heat their houses/buildings by doing this they hope to help increase the generation of heat from renewable energy sources (instead of fossil fuels). RHI helps in not only reducing gas emissions but also by helping to meet targets for reducing the effects of climate change. There are three steps involved: Step 1: Heat Systems such as Solar Thermals or Heat Pumps are installed in a property. Step 2: The actual energy produced by renewable system is measured. Step 3: Customers get paid a fixed amount as per the energy produced. WHAT IS INCLUDED? Domestic RHI This scheme is designed to support the uptake of renewable heating among domestic consumers. The scheme covers single domestic dwellings and is open for homeowners, private landlords, social landlords and self-builders. This scheme is not open for new build properties other then self build. If you are off the mains gas network and using expensive oil, LPG or electricity then RHI is for you. There are four various heating systems that a household can install which qualify for RHI and they are as follows: Solar Thermal Biomass boilers Ground Source Heat Pumps Air Source Heat Pumps HOW MUCH I GET The amount the customer receives, would depend on the Renewable Heat system he/she has installed and the rate given will be for the duration of his/her RHI payment period. The income would be paid quarterly, directly from Ofgem into customers’ bank account. RHI payments are calculated based upon customer’s EPC and estimation on the usage of hot water and heating. The current Tariff rates HEAT SYSTEM PAYMENT FOR KILLOWATT HOUR (KWH) BIOMASS BOILERS 12.2 p GROUND SOURCE HEAT PUMPS 18.8 p AIR-TO-WATER HEAT PUMPS 7.3 p SOLAR THERMAL FOR HOT WATER 19.2 p WHAT TO DO NEXT You can pay upfront or you can choose Green Deal Finance as it could even reduce your installation cost. After carrying out a GDAR the GDA will recommend which system would be better for your home, the estimated cost and how much money you could earn in terms of RHI payments. In order to get RHI you need to: Book a Green Deal Assessment with us as we are approved Green Deal Advisor Organization. After an assessment we will be able to suggest the savings you will make and we can also recommend a suitable system size. We will arrange a MCS certified installer to install the new renewable heating system at your premises. Once the installation has been completed, we will fill out the RHI application form and submit it on your behalf with all the relevant documents on the website of Ofgem.

By emulating the ingenuity of termites, Zimbabwean architect Mick Pearce used an approach called biomimicry to design a natural cooling system that harnessed nature. The result is an architectural marvel that achieves 90 percent passive climate control by taking cool air into the building at night and expelling heat throughout the day. In this first installation of the Decoder series, see how the Eastgate Centre in Harare, Zimbabwe utilizes a termite-inspired climate control system.

How to Balance Heating System Radiators - Plumbing Tips
AMAZON TOOL SHOP HERE: https://www.amazon.co.uk/shop/plumberparts ***VISIT OUR SPONSORS*** http://www.traderadiators.com | http://www.wilo.co.uk | http://www.adey.com A brief video on how to balance heating system radiators. Includes lockshield positions and TRV's. Plumbing Tips - diy. For more information visit our website at http://www.plumberparts.co.uk Today, I'm going to tell you about balancing heating systems. Why you should do it, the symptoms that mean you might have to do it and how to do it. Firstly, lets have a look at the general layout of a heating system. Have a look at schematically because that will help you understand why balancing a heating system is so important. Let's say we have two stories, level one and ground. We have the boiler at the bottom. Coming out of the boiler we have a pump that goes up, through diverter valve, through some radiator's upstairs. And, then downstairs, with common returns, going back to the boiler. Okay, so we've got radiator's here. The first reason that heating systems should be balanced is even if there is a pump on the heating system, hot water naturally likes to gravitate up. And stay upstairs and then make it's quick route back to the boiler. So what we often find, is the radiator's upstairs are getting loads of heat when the ones downstairs, are still really quite cold. So what you should do, is go to the lock shield on the radiator's upstairs, close them and then open them about a quarter of a turn. You won't necessarily see any difference in the radiator's heat capacity or not but you will noticethat more hot water flow is diverted to the radiator's downstairs. Now, you go downstairs make sure those radiators are open and that means the heating system should be balanced. Another reason you should balance your heating system is, say, this radiator is getting hot, that one's getting hot, and this one's getting hot, the last radiator on the line isn't getting so hot. That's because these three radiators are effectively pinching all the hot water flow delivered by the boiler and the pump. What you do then, is remove the lock shield on these radiator's here, straddle those two up there, down, shut them, give them a quarter of a turn. This one here, bring that down, shut them, then give a quarter of a turn. We also do a video on one radiator isn't getting hot 'cause it can be more than one reason, not just the fact the system isn't balanced. But, that is a brief idea of how you balance the system and why. Now, let's take a quick look at the lock shield, how to shut it and also, give it that quarter of a turn to make sure it is all balanced. So, here we are, upstairs, okay. Now the radiator's up here get really hot, so let's have a look at how we're gonna straddle this one down and balance this system. So, here we are with our first upstairs radiator. There is four in this system upstairs and do the same thing to each one. Here's the lock shield here, note the T on the end. Pop the lock shield cap off, and close it by turning it anti-clockwise. Once it's fully closed, just slack it back a quarter of a turn. Do that to each radiator upstairs, and you should find then that each radiator side of the heating system is balanced. Now, let's have a look at what you can do to balance out the hot water coil on your heating cylinder, if you have an indirect one. Right, so we had a look at how to balance the radiators on a heating system. Now, we are going to have a look at how to balance the hot water coil on the indirect cylinder. A lot of houses in the UK have indirect hot water coils on the cylinder. That means, hot water from boiler is passed through a coil in the cylinder and that heats the water up. Now, often these coils are 22 mm in pipe size and when the valve opens up to let hot water through that coil, it pinches loads of heat from the radiators. Therefore, the indirect hot water coil should also be balanced and regulated. Most plumbers when installing an indirect hot water cylinder, will put a flow regulating valve on the return side of the coil. Let's have a look at it. So, you have your boiler, your pump and your three port valve or if you have less plan, it will just be a two port valve for each side. You have all your radiators with their frozen returns. We have the flow coming up here from the boiler, goes through the valve into our hot water coil and our cylinder and then back out. And, it's here that we fit the flow regulating valve on the return side of the hot water coil. That will go back into the return side of the boiler. So, to recap, we have the boiler, the pump and our diverter valves. The radiators upstairs have been straddled down and regulated. The ones downstairs are getting a good flow of hot water. We've also straddled down the return on the indirect hot water cylinder and the whole heating system is now working properly.

All about Un-vented hot and cold water combination valves and pressure reducing valves.. We show you how they work, how to replace one that is faulty on your system and how to strip a combination valve down. We even have hand drawn diagrams all about how they reduce pressure, vent high pressure and have a balanced cold water feed out for showers and mixer taps. AMAZON TOOL SHOP HERE: https://www.amazon.co.uk/shop/plumberparts ***VISIT OUR SPONSORS*** http://www.traderadiators.com | http://www.wilo.co.uk | http://www.adey.com ***WEBSITE*** http://www.plumberparts.co.uk Hello, if you've been lucky enough to stumble across this plumberparts.co.uk video about combination valves on unvented hot water systems, then, great, we can have a look at that any minute now. Please do subscribe to our videos by clicking on the car that's appearing right now. We do loads of videos on plumbing stuff, and also we do plumbing disaster photos and videos that you guys send in to us on a daily basis. Anyway, I hope you enjoy the video, and remember of one, to hold tight. Plumberparts.co.uk, honest reviews and advice. So, this is just a really quick video to tell you about what combination valves do, how they work, and their basic use in an unvented system. We've got one here that, as you can see, is leaking from the pressure regular top spring on here, and basically what we're gonna do now is to swap that over for a new one in a second. But before we do that, I'm just gonna show you how they work and the basic principle of what they do. So, coming into the top here, we've got mains cold water coming in at mains pressure, whatever that may be. Now, remember that the mains pressure can fluctuate up and down according to what time of day it is. Generally it goes up at night because, obviously, less people are using the water. And, obviously, during the day it goes down a little bit. So we want to protect our whole hot water system, and our tank here, from getting so over-pressurized that it bursts. Especially if you live in a mains water area where the pressure can over seven bar at night, that's way too much for these beasts. So the first principle thing that a combination valve does, is regulate the amount of pressure that's going into the system. And if you look on the end here, you'll see that it says three bar on this. So we know now that the pressure going into the system is three bar. So another they can do, which is really good, is you can remove this nipple here, unscrew that plastic bung, and then screw a pressure gauge in so you can see what the pressure is coming into your system. So that's really handy. And then the next thing they can do on the way a bit down here, we have an eight bar pressure relief valve. Obviously, it's pretty self-explanatory what they do. If the pressure goes over eight bar in the system, ie. this fails, that pressure relief valve is gonna start dumping water into this tundish here, and then running away outside. The system that this combination valve is fitted on at the moment is a mega-flow.
