These are called towel radiator valves. There are three options available and they depend on the pipework involved.
The first, of course, is the circumference of the pipes already in place. It is no use to buy a radiator online with apertures that are different from what is already in your home. It makes sense to purchase valves to complement the towel heater.
Secondly and thirdly there are two types of valves available, straight and angled valves. You can also opt to have thermostatic valves fitted, but most people do not bother where towel rails are concerned.
If you are having one of the stylish ladder radiators fitted, you may want to buy a lockshield valve which you can regulate manually. These are an up to date addition to an already attractive installation.
Towel radiators have become something of a must-have in the modern bathroom scene. They are both practical in drying the family’s towels as well as keeping this damp space warm and cosy when having a bath or shower.
As a rule straight valves are used if the pipework comes through the floor of the room. In the case where they come through the wall and there is no pipework showing, angled valves are being used. In the latter case the angled valves are facing forward making for a neat finish.
If your towel radiator is connected to the central heating system, they will come on when the heating is running. If they are independent of the system you may want to have a thermostatic valve fitted so that the heating in the bathroom can be regulated thermostatically.
When you order your radiator you must ensure that the accompanying valves are of good quality. This is important if your radiator runs off the heating system.
