Upstairs radiators always on?

[dbairduk]

Hi I am a new poster and have just purchased my first house!
I have A gas boiler going into a cylinder storage tank. The gas boiler is downstairs and the cylinder upstairs.
The radiators upstairs always seem warm or hot. Even when the heating and downstairs ones are off and cold. Is this common? And where are the radiators getting the hot water from to sustain the heat?

Any advice apreciated

is it just 1 rad getting hot...or all of them ?

the bathroom alwasy on and the other 2 just warm

£1 bet its been converted from solid fuel at some point the bathroom rad is the heat leak

erm the house is about 9 years old, i don't think there has been a solid fuel burner in here as no chimney or anything for that?

You may have a mid-position valve that isn't fully shutting off the heating circuit when the hot water is on.

Normally the valve would be in the airing cupboard.

Sorry for the "erm" lol

Do you have a mid position valve on your system?

motor might be a different colour

If it's gravity fed hot water your bathroom radiator may become warm on the circulation of the water, turn off the radiator in summer if it is.

more likely to be backflow from the cylinder return if upstairs rads are heating when only using boiler to heat water this is a regular problem a single check valve just before the last joint on the heat circuit cures it

Could it be the bathroom radiator is on the hot water circuit?
