All you need to know about Radiator valves.
Thermostatic radiator valves (TRV's) will control the temperature of the heated towel rail or radiator irrelevant of the incoming water temperature, so it will give the option to control each radiator on your heating system. They come in both straight and angled versions for either wall or floor connections.
Thermostatic radiator valves work by sensing the temperature in the room and will adjust the flow of water into the towel rail to suit.
They can be fitted to either the flow or return side of the heating system.
Standard Radiator Valves
These are the most common valves used for controlling Heated towel rails or radiators. The idea is that you slow down the flow for the temperature adjustment, this is not as good as a thermostatic valve but you can still achieve the required control, The main use is as a form of isolating the water flow.
Standard Radiator valves come in both straight and angled valves (see below).
Straight radiator valves are very common for towel rail use where the pipes are coming up from the floor, the connection to a towel rail is mainly from the bottom with a 1/2" bsp thread, in this case the pipes will be straight through the floor and straight into the bottom of the towel rail.
The flow is normally controlled via the return side of the towel Rail by turning down the flow.
Angled Radiator valves are normal used with towel rails where the connection to the pipework is from the wall, as the connection is generally at the bottom of the towel rail in a 1/2" bsp connection the valve will bend back to the wall.
