New houses may have this, because of new housing regulations. However, existing older systems will not usually have an AUTOMATIC BYPASS (PRESSURE BALANCING) VALVE, or ABV fitted to the system.These are required to cater for the possibility that the majority of radiators are closed off due to low TRV settings, but high room thermostat settings keeping the boiler cycling. Since the circulating pump would still be running, the pressure in the system would increase.

It's best to set your TRV to a middle setting and see if the room is warm enough. If the room is too warm, turn the TRV down by 1, if the room is too cold, turn the TRV up by 1. A middle setting corresponds to approximately 20ºC (68F). Do NOT turn the TRV fully ON or fully OFF to make the room you are in warmer or cooler - this will waste fuel. Turn it a little way and let it do the work.

These older valves are identified by having both pipe connections in one radiator valve at one side of the radiator. If new radiators are being fitted it may be advisable to also renew the valves.

The TRV controls the radiators temperature by sensing the room air temperature and automatically opening and closing the flow to the radiator to maintain a preset temperature. A manual valve controls the temperature of the radiator regardless of how warm the room already is. On large radiators (above 1800 watts, or where the radiator is oversized for the room) we recommend TRV because they save you having to get up to turn the radiator up and down, but they are not essential.

There may be one (or more) radiators in your home, usually the bathroom, which does not have a TRV. This does not mean that one is missing. There sometimes needs to be one radiator always open to allow water to flow into it if all the others are turned off, to avoid damage to the pump or boiler. Sometimes it is not necessary to have a TRV in the room with the main room thermostat.

I have had a few mails on this lately. It is possible for a TRV to stick in the closed position, and most of them have a removable thermostatic head, to reveal the valve plunger beneath it. This should be free to move up and down, but the plunger pin does not move very much, usually not more that about 5 or 6mm. About 2 pounds pressure with a flat object should move the pin down, and it should be free to move up to its highest position by itself with the thermostatic head off.

A thermostatic radiator valve (TRV) is shown in the image to the right. You will find it on the pipework at the top or bottom of your radiator. It gives you greater control over the heat from each individual radiator. Each TRV can be set to a temperature to suit you, so you can have different temperatures in different rooms.

Yes, they will. Our unique removable magnetic front panels allows access to all radiator parts and valves.

A - Thermostatic valves control the radiator temperature via a sensor which senses the air temperature in the room. Once the preset temperature has been reached the valve automatically opens and closes the flow of hot water to the radiator to maintain that temperature. A manual valve does not control the temperature of the radiator regardless of how warm the room is already. If the room gets too hot, you can turn it off easily. A - They are both measurements of heat output.

The fitting of a thermostatic radiator valve (TRV) to a radiator gives room temperature comfort control and can help to avoid overheating if a radiator is too large for the room. This piece of equipment provides an extra fine tuning control to central heating, by allowing individual room temperatures to be maintained by sensing room temperature and automatically adjusting the flow of hot water into the radiator.

Wrap at least five turns of PTFE tape around the threaded tails of the valves and screw them into the radiator. Make sure the PTFE tape stays on the thread rather than just running along it as you tighten. If it does run, undo the valve and roughen the thread slightly with a hacksaw blade then re-tape the thread.

No, they don't. A bus radiator is on the side of the coach and the cooling fan has to pull air through it. On a truck, as soon as you get up to 35 MPH, air is pushing its way into it. The front radiator is a far superior design for a truck that works much heavier carrying an average weight of 80,000 lbs., where a bus seldom carries more than 40,000 lbs. The side radiator design for a bus is very adequate that engine.

Decorative covers can be utilised, however they will significantly reduce the output of a radiator. The amount of heat reduction is dependent on the actual design of the cabinet so we cannot give an exact heat reduction figure. Thermostatic radiator valves should not be fitted inside covers.

All our ready made and made to measure covers come with complete fixing instructions. Assembly of the cover only takes a few minutes. Both ready made and made to measure designs use "wall hook" fixings and once these are fitted to the wall removal, and repositioning, of the whole cover for access takes just seconds. In this way the whole cover surround can be taken off very easily for full access.

If you have fitted a standard radiator in the past, then you should have no problem fitting one from our designer range. All our radiators have brackets and screws included.

The Radiator Company radiators / towel rails are compatible with normal central heating systems and have British Standard fittings. The Radiator Company radiators work with all types of boiler, and with all types of circuit including sealed systems, combination boiler systems and condensing, closed-circuit systems with an expansion tank. (If you have an expansion tank, the top of the highest radiator must be at least 60 cm ? two feet ? below it.

All of our radiators are compatible with normal central heating systems and have British Standard fittings. On an existing system you can replace all the radiators or just the ones you want.

Because it's easier, quicker and more effective! Let us explain: Waterflow, not pressure, is the basis for cleaning domestic heating systems. The pump in a Powerflush machine is more than capable of pushing water around most domestic heating systems. Combining that capability with the chemical properties of our Sludge & Flux Remover and Siltfree means that you can effectively clean a domestic heating system in one loop, rather than trying to clean one radiator at a time using physical force.
