There is NO separate control for heating and hot water, it's either both on or both off. So for hot water in the summer, all rads have to be turned off at the TRV's. There are no motorised valve to switch between hot water and heating, effectively the hot water coil is simply a giant radiator.
Is it possible to heat a house with hot water?
Heating with hot water, or boilers, are less common now than they used to be, but they are still a viable option for many homes. Hydronic heating systems boil water to the appropriate temperatures and then send the water through pipes to radiators, baseboard heaters, or radiant floor tubes.
What do I need to know about heating and hot water?
To start with, you need to know a bit about your heating and hot water systems (they may well be the same thing) and have a top-line understanding of how they work. A central heating system made up of radiators and a boiler that also provides your hot water – this is the most usual kind of heating system in the UK [1].
What is central heating and how does it work?
With central heating, you have a single boiler heating up your water. This water is then pumped through pipes to radiators installed in different rooms around the house. The same boiler also provides hot water in the bathroom (s), kitchen and utility room.
What are the different types of central heating?
A central heating system made up of radiators and a boiler that also provides your hot water – this is the most usual kind of heating system in the UK [1]. Individual storage heaters, or standalone heaters, plus a boiler for your hot water.
Can you have central heating on without hot water?
If you are leaving the house empty for more than a few days, it should be safe to leave your heating on, however, even if you do turn off the water. It can be useful to have your central heating ticking over on a low temperature while you're not there with the help of a smart thermostat.
Is hot water connected to central heating?
A central heating system has pipework and radiators which are connected to a boiler. The boiler provides the heat and the pump moves heated water from the boiler through the pipework to the radiators, and back to the boiler for reheating. It also provides hot water to the hot taps in your home.
Are hot water and heating separate?
There is NO separate control for heating and hot water, it's either both on or both off. So for hot water in the summer, all rads have to be turned off at the TRV's. There are no motorised valve to switch between hot water and heating, effectively the hot water coil is simply a giant radiator.
Why does my heating come on with hot water?
The most likely reasons for your radiators heating up when you turn on the hot water taps would be a fault in the check valve in older boilers, or the diverter valve in newer ones. Both control the flow of heat and hot water to the different parts of your heating system.
Do radiators use hot water tank?
A regular boiler sends hot water to your radiators and a hot water cylinder, also known as a hot water tank.
How does a heating and hot water system work?
Hot water from the boiler passes through the heating coil within the cylinder, transferring its heat to the water inside the cylinder as it passes, but never mixing with the water inside the cylinder. The heat is transferred and the water from the coil comes back around to the boiler to be heated up again.
Can a boiler do hot water and heating at the same time?
A combi, or combination, boiler is a type of boiler that combines a water heating system and central heating unit into a single body. This acts as a unified way to handle heating and hot water without the need for a separate tank.
Can a boiler heat water and central heating at the same time?
A combination boiler (almost always called a “combi boiler”) is both your central heating boiler and water heater in a single, neat unit. One of their real benefits is that they heat the water directly from the mains, rather than by heating a tank of water. Like all modern boilers, combis are condensing boilers.

Will my heating work if water turned off?
If the water supply is cut off but your cold water storage tank is full, it's still safe to run your central heating. However you should not use your hot water. A system with a cold water storage tank will give a limited amount of water after the supply is cut off, but you risk running the storage tank dry.
Why is hot water working but not heating?
If you've got hot water, but no central heating then there are more issues it could be if it's not the thermostat or the boiler pressure. Common reasons for this particular fault are broken diaphragms and airlocks, or a motorised valve failing.
Why does my central heating not come on?
Check your thermostats If the thermostat is set too low, the heating will not come on until the room temperature is lower than the temperature you have set the thermostat to. Turn the thermostat up to its highest setting and see if this resolves the problem.
Can I drain my radiators and still have hot water?
There's no need to switch off the water supply when removing a radiator - the water will cut off from the radiator as soon as you close the valves. However, we would definitely advise you to switch off the central heating and wait for the radiator to fully cool before starting work.
Where does hot water come from in a house?
Today in the United States, domestic hot water used in homes is most commonly heated with natural gas, electric resistance, or a heat pump. Electric heat pump water heaters are significantly more efficient than electric resistance water heaters, but also more expensive to purchase.
Will my heating work if water turned off?
If the water supply is cut off but your cold water storage tank is full, it's still safe to run your central heating. However you should not use your hot water. A system with a cold water storage tank will give a limited amount of water after the supply is cut off, but you risk running the storage tank dry.
Why is hot water not working?
What does it mean if the water heater is not producing hot water? It is possible that the circuit breaker tripped or a fuse blew, so check those first if you are not getting hot water from your water heater. If that's not the issue, then it could be that the heating element has burned out and needs to be replaced.
Where is the pump located on a boiler?
edit3: The pump is situated directly above the boiler. There doesn't appear to be any more valves, either by the boiler, or by the cylinder.
Can a timer/programmer be used for hot water?
Agree with some of the previous comments. The timer/programmer allows for separate use of heating/hot water. It sounds like you need an engineer visit to confirm what system you have but sounds like it could possibly be an issue with the zone valve.
Why does my furnace make a noise?
When you have a furnace or forced air heating system, there’s a fair amount of noise that’s unavoidable. As the fan blower distributes the air throughout the air ducts, you may hear that creaking sound as cold ducts heat up. You’ll also hear the fan and the air circulation. With hot water heating, the air isn’t forced out so the heating system is quiet. Learn more about what is forced air heating.
Why does forced air heating make my room feel warmer?
This can lead to drafts. With radiated heat, you may feel warmer because there’s no breeze caused by the hot air being blown through ducts and out into your room.
Does a water heater keep you warm?
One of the biggest benefits that homeowners enjoy with a hot water heating system is the residual warmth that continues even after you shut the system off. The water in the radiator remains hot so you can continue to feel the heat even hours later. By comparison, a forced-air heating system stops distributing warm air as soon as you shut it off. This can lead to drafts.
Is it expensive to install a hot water system?
A hot water heating system will be more expensive to install. There is the possibility that boiler systems could leak if a pipe breaks since they use water to warm the air. Most systems have at least a 15-year lifespan and breaks are very rare.
What is central heating?
With central heating, you have a single boiler heating up your water. This water is then pumped through pipes to radiators installed in different rooms around the house. The same boiler also provides hot water in the bathroom (s), kitchen and utility room.
How can I create a more energy-efficient heating system in my home?
Turn down the thermostat. According to the Energy Saving Trust, just 1 centigrade could save a typical home around £90 per year.
How does a combi boiler work?
A combi boiler provides hot water instantly, as soon as you turn on a tap. The water is heated as it passes through the boiler, so there’s no need for a cylinder, and you can have hot water for baths or washing up whenever you want. A regular boiler works with a hot water cylinder. You programme it to heat the water in the cylinder ...
What is a storage heater?
Individual storage heaters, or standalone heaters, plus a boiler for your hot water. A heating system that pumps warm air into rooms through vents in the walls, generated from a boiler that also provides your hot water. Underfloor heating – but you’re unlikely to have this in every room, so it would probably work with one ...
What to do if you haven't had a new boiler?
If you haven’t had a new boiler within the last 10 years, look into replacing it with a newer model. Boilers are improving and becoming more energy efficient all the time. Radiators have also improved over the years, so look into replacing your current system with newer, more energy-efficient radiators.
How long before you arrive to switch on your thermostat?
Find out whether your controls or thermostat will work remotely, so you can switch on the heating exactly half an hour before you’re due to arrive home, rather than always switching on at the same time each day, whether you’re in or not. Make sure your home is well insulated and draught proofed.
How to make your home more energy efficient?
Make sure your home is well insulated and draught proofed. Change to a cheaper or lower-carbon fuel or technology – this is a great way to create totally energy-efficient heating systems, but it may be expensive and disruptive, so do plenty of research before you decide.
What is hydronic baseboard heating?
Hydronic baseboard heating is radiant heat too. It is the same as the other systems and relies on radiant heat to warm a room. However, technology caught up with design and replaced traditional radiators with a series of metal fins that are combined with convection to move warm air from the baseboard unit around the room more effectively. The baseboard concept is due to the well-known fact that hot air rises so the most effective way to heat a room is to introduce the warm air at floor level, which will displace the cooler air as it rises.
What is hot water heating?
Hot water heating systems are built around the premise of radiant heat. Water is heated by a boiler and circulated throughout a building--usually homes (older homes , especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room. There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems.
What are the different types of hot water systems?
The heat transfers to the air in the room. There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems. Advertisement.
Why should water be drained and replaced?
Second, the water should be drained and replaced throughout the system periodically, particularly if it is unfiltered water, because minerals will build up in the pipes, restricting flow and diminishing heating efficiency. Advertisement.
How to use air vent valves?
The first is to use the air vent valves to release air that has become trapped into any of the three systems. Because the air rises through the water in the system, the most air will collect at the highest-level radiators. So tap the air vents beginning at the highest point in the system and work your way down. Air is trapped in the radiators throughout the system , not just the top radiators. Second, the water should be drained and replaced throughout the system periodically, particularly if it is unfiltered water, because minerals will build up in the pipes, restricting flow and diminishing heating efficiency.
Why does water circulate in gravity?
In a gravity system, the circulation of water is due primarily to thermal and density differences between hot and cold water. As water heats, it expands, displacing the cooler and less dense cooler water throughout the system. If you are thinking that water expands as it gets colder, it does, but only as it approaches freezing temperature.
Is plumbing the same as gravity?
The plumbing is essentially the same as in a gravity system except a pump provides the circulation in a more efficient and effect way. It allows the water to circulate more quickly, replacing the cooled water in the higher elevations and with the hotter water from the boiler.
How Does Baseboard Heating Work?
The important components of the system include the boiler, the water connection, the pipes, and the baseboard radiators. To understand how the system works, it’s important to consider each element, both regarding its primary function and how it connects to the rest of the system.
How does a boiler work?
The boiler takes in water from the water supply system and heats it to a high temperature. The heated water then feeds into the baseboard heating system’s pipes, with the piping leading from the boiler out to every room in the house. This piping network exists as a self-contained system, meaning that the pipes run parallel to ...
What is forced air heating?
Forced air systems are very common heating systems for new construction, as the ductwork required can be installed during construction. Radiator heat is a similar system to baseboard heating that nevertheless has several important distinctions. Forced air systems typically use ductwork and vents to bring heated air into a room from a furnace.
How does forced air work?
Forced air systems typically use ductwork and vents to bring heated air into a room from a furnace. An advantage of forced air over baseboard heat is the speed of heating. By forcing hot air into the target room, the ambient temperature rapidly increases. This “burst” approach to heating can be very inviting when returning home on a cold day, because it simply feels warmer. On the other hand, heat bursts from a forced-air system are loud can cause an intermittent breeze that stops when the air is no longer being forced through. Finally, the dry heat of forced tends to remove a greater amount of humidity which can worsen static electricity in the room or cause dry skin issues for occupants.
How does a closed circuit heating system work?
To complete the closed circuit, the now-cooled water returns to the boiler through the system’s return pipes. As this process happens, new hot water cycles into the baseboards while the cool water is reheated in the boiler.
How far up the wall do radiators extend?
Unlike baseboard heat, however, radiators have a much greater size profile in the room, often extending three or more feet up the wall. This design creates more radiator surface area, which allows radiators to heat a room more quickly than a baseboard heater.
What happens when hot water cycles into baseboards?
The result, ultimately, is a continuous cycle that results in a consistent heat source in every room in the house.
What is a central heating pump?
A central heating pump is a small mechanical tool installed on your central heating system which is used to speed up the process of circulating hot water from your boiler to your radiators and back to the boiler.
What are the main components of a central heating pump?
Central heating pumps are not complicated devices. Most boiler pumps will be made up of six components, each of which you can see in the diagram below.
Where is my central heating pump located?
Each home is different, and the location of your central heating pump will be determined by the location of the boiler or the expertise of the plumber who installed it.
Does a central heating pump use electricity?
One of the great things about central heating pumps is that they only use electricity when you switch on the central heating system. This helps you save $$$ on your electricity bills.
How much power does a central heating pump use?
Most domestic central heating pumps run on 240 volts and use around 50 watts of power, which is a lot less than the amount of power needed to operate a kettle. Saying this, your central heating pump is unlikely to be on full power and probably not running all day, so it's possible that you will be using less than half the power of operating a kettle a few times a day in a modern, well-insulated home.
What is a pressure adjust dial?
The pressure adjust dial is an electronic component of a central heating pump that allows you to increase the pressure of the water in your central heating system. If you are finding that specific radiators are not getting the required heat, then simply increase the pressure using the adjustment dial. Pump Bleed Screw.
What is the number to call for pump advice?
If you’re struggling for advice, call our dedicated pump experts for free advice on 0800 112 3134 or 0333 577 3134.
How do central heating systems work?
Central heating systems operate by using water to transmit heat. The system has a source of very hot water, usually an electric or gas-powered boiler, which heats the water in pipes that are throughout your home. Then when you turn on the faucet for hot water, it gets sent through those same pipes, and voila! Hot shower ready.
How can you get the hot water to last longer?
If you are worried about how long hot water lasts in your home, then a few things can help.
How to have the most out of your water heating system?
If you want to get the most out of your water heating system, it’s important that you make sure everything is working properly!
What is the brown wire on a boiler valve?
Cheers . Obvious which valve is for the cylinder !! The brown wire brings voltage to the valves motor ,motor turns a spindle ( shaft basically) that opens the port allowing water to flow thru the brass body into the cylinder. The spindle also triggers a micro switch ,which has a seperate voltage supply, and allows voltage to flow through the orange wire to the boiler and pump. The valve is getting voltage on the brown as it is opening and you are getting hot water. If it wasn't the valves default position is closed, under spring pressure, and you would not get hot water . So I suspect the micro switch is not being made / or is goosed.
Where is the valve that controls the flow of water into the cylinders coil?
Can you post pics of pipework around cylinder , particularly the motorised valves ,the valve that controls the flow of water into the cylinders coil will be on a pipe that goes directly to the cylinder. Electrical testing would be done at the wiring centre.
Is the flash reveals all it seems?
Sure - here you go, excuse the mucky airing cupboard, the flash reveals all it seems!
