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.

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.

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.

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.

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.

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.

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.

Yes, but we suggest that you double the amount of FX2 to 5 litres. If the distributor / spreader tube, which directs the incoming water towards the far side of the radiator, has broken away, so that the entrance and exit are effectively only 1/2" apart, any flushing effect on that radiator will be minimal. Conversion to opposing inlet and outlet valves is a better long term proposition.

Although the vast majority of our customers enclose it, the thermostatic valves should ideally remain outside of the radiator cover if they are to sense the temperature of the room correctly. If you would like to keep the thermostatic valve outside of the radiator cover, the side of the cover that the valve is on will need to fit between the radiator and the valve. When fitting, a small cut will need to be made in the cover to receive the pipe between the radiator and the valve.

A TMV is used to control the temperature of the hot water supply to the manifold. It is necessary when the design temperature is significantly lower than the supply water temperature from the heat source. The TMV installs in the plumbing supply and return lines between the manifold and the heat source. It blends return loop water from the manifold and supply water from the heat source to a manually set temperature.

A No its a manual valve but the 'Traditional' valve found on our valve page, is thermostatic and comes in a range of brass, chrome, and nickel. We are currently manufacturing a further range of traditional style thermostatic valves, and will be adding these to our range in September 07.

Geez, wouldn't that be nice! To date we have not found a way to change your hose without lowering the fluid in your radiator. When we find it you'll be the first to know.

Ordinarily the radiant tubing must run at a lower temperature than the baseboard. This means that a mixing valve is used to provide a lower temperature for the radiant heating tube. It might be possible to avoid the expense of the mixing valve if the baseboard can be run at a lower temperature and if you select a radiant tubing with a high temperature rating, but the situation will not be ideal.

Back in the 50s, MCI installed radiators in the back of the cabin structure above the floor. This idea was to prevent an ongoing problem of leaves, dirt, and debris being sucked in the low slung radiator. Over the years, all manufacturers install their radiators next to the engine on the left side. The main reason is roads are far superior to what they were 50 years ago and there is not as much debris on the highways.

Visual inspection at periodic intervals (most easily performed while checking the oil level) is always a good money saving idea. A great deal about the condition of the ENTIRE cooling system can be quickly learned by checking both the INSIDE and OUTSIDE of the radiator! Inspect the radiator for coolant seepage or stains around soldered seams of the sides, top and bottom of the radiator. Remove bugs and debris from the finned core area while checking for coolant leaks.

Suction relief valves are mounted as close to the suction mouth of the suction line as is practical. It can be opened manually to allow extra water into the slurry, or automatically if the suction or discharge lines begin to plug, as measured by vacuum and pressure sensors. The suction relief can also be connected to a Production Meter System to help keep at a consistent level of production.

If a valve is faulty you will not necessary see any distinguishing marks. If you feel a valve may be faulty due to sound quality or no glow from one or more of the valves you can see through the back grill we recommend you immediately switch the amplifier off and have it checked by a qualified engineer before using it again.
