DIYbanter - View Single Post - Central heating a hot water system question

declared for all the world to hear...
After serious thinking Jon wrote :
Should my radiators come on when the hot water comes on - even though
the heating is set to "off" on the programmer, and it's so hot in the
house that turning the stat up to maximum (30) does not cause it to
"click" on?

No it should not. You have a wiring error or a fault with the valve.
Call the installer back if it is a new system.

It's 9 years old (built with the house). The pump was replaced recently
but I visually observed the whole process and he simply did remove the
old pump and refit the new one.
