Radiators warm when only hot water on ??

[swayzak]

Hi

I had a visit from a HeatTeam engineer today to check my Potterton Suprima 50 L (due to isolated lockout last week).

She ran some tests but said it seemed OK.

However this evening I notice the rads are warm when hot water (NOT heating) is on !

This doesn't seem right - can someone advise please ?


thanks

Motorised valve is letting by, if Honeywell you can replace the seat at reasonable cost others need a new valve body do you have a 3 port valve, or a pair of 2 port valves and what make are they? (they a probably in the airing cupboard)

The boiler is in the loft.

Where are the "motorised valves" ?

I have never visited your House, so I have no idea!!
they are usually near the pump in the Airing Cupboard

OK - thanks.

None the wiser as I don't have an airing cupboard ....
