Hi, has anyone tried this? I have Googled it, and found one from Hamilton Gas Products but have never seen anyone use these or any others. Surely it would invaluable, so when the heating comes on you could, say, warm the bathroom up for the hour before you use it in the morning, or the loo, but not at any other time you want the central heating to come on.
Okay, you can sometimes run around turning the valves on and off but it is such a fiddle.
Any thoughts? Do they really attach to any kind of radiator?
