We have a bathroom towel rail in the central heating circuit which has a supplementary 300w heating element which we use for short periods in the summer months. The electrical element is activated via a floor level fused switch located outside the bathroom and is frequently left on longer than intended.
I was going to replace the existing switch with an electronic timer switch so that the rail could be set to come on an off automatically. The switch I have is rated up to 400w but only switches the live. I notice that the existing switch is double pole, is this strictly necessary in this context and if so, can anyone recommend a suitable timer switch which could be used as a straight replacement?
Thanks for any advice. Thomas
