    We have had a new boiler and hot water tank fitted. We now want to install a heated towel rail in our bathroom, but should it go on the HW or CH circuit? I can see the benefits of both, but which is the best?

    I put mine on the pump output, effectively turning it on whenever the boiler fires (hot water, heating, or both). Strictly speaking this does not meet the Building Regs Part L1 requirement for time & temperature control, though a TRV on it could be argued as complying as it would still be time controlled, and the TRV would prevent overheating of the (bath)room.

    if you want towel rail to come on in the summer then do it off the hot water circuit if not then of the heating circuit :cool:

    Thanks gazthepottertonengineer, i think that we would like to run it in the Summer. Could you advise the best way to do it? I have a Potterton Suprema HE boiler and i can see a silver box with Y Plan on it near the pump. The hot water tank has a pipe into the top, a middle pipe that goes to the Y Plan box and pump and a bottom pipe that seems to go to a vent(?!) and runs back to the top of the boiler.

    I went they way Mildrews mate suggests. Reason being is that my HW is controlled by a thermostat on the cylinder and so only runs for aproximately 15 minutes twice a day. I didn't think that was long enough to dry towels.

    That being said, if you connected a towel rail to the HW, it would come on if you used a lot of water, say ran a bath, but not if you used an electric instantaneous shower not connected to the cylinder.
