Upstair Radiators getting hot when system set to heat Water

robford · 16 May 2006

Hello and thanks for reading this,

I have a Gravity Fed Gloworm system (not combi) Problem is, lately, when the system is set just to heat the water cylinder, the upstairs rads also get hot.(downstairs remain cold)

I understand that CH systems are complicated and diverse but could someone offer a reason for this?

Regards...Rob

It could be that the anti-gravity valve situated on your primary flow ( flow pipe leaving the boiler and going towards your CH ssystem) is knackered if you are sure that this prob was not occuring before.
