What is a BTU
*A British Thermal Unit (BTU) is the amount of heat energy needed to raise the temperature of one pound of water by one degree F. This is the standard measurement used to state the amount of energy that a fuel has as well as the amount of output of any heat generating device.
All outputs listed are calculated in line with the European BSEN442 Testing Standard at ∆t50° (the latest standards for modern boiler systems). Sometime they may be listed outputs at ∆t60° to allow for the older boiler systems. To convert Δt50° to Δt60° simply multiply x 1.264.
What is a Thermostatic Valve
*As its name implies, it is a radiator valve, but it incorporates an internal thermostat, so that the temperature of the individual radiator, and therefore that specific room, can be better controlled. It is commonly abbreviated to TRV. Because of the control knob and integrated thermostatic mechanism, they are quite a bit larger than a standard valve.
Where is the best place to put a radiator?
*Tests prove that the best place is in the coldest part of the room, usually near a window. Placing a radiator under the window will counteract the cold downdraughts and prevent condensation.
However, with double glazed windows and modern levels of insulation, it is usually possible to locate your radiators away from windows in the position you decide is most pleasing aesthetically.
If you would like the radiator/valve to be delivered to a different address, please note the SagePay page with the Billing Address.
