After a weekend away i have come back to find my heating or hot water not working at all.
I have checked the usual things i have problems with ie air in the system, header tank not filling etc.
This time there seems to be no circulation at all and the only thing getting (very) hot is the pump ( a 2 speed grundfoss super 4 V806) its making no sound at all to indicate movement, would this point to a broken pump ?
If so can a pump be replaced without draining the system ? i can see 4 allen bolts securing it to the pipework. How much would a pump cost ?
Other problems i have been having just lately are the header tank getting full of hot water. The main boiler is a Vulcan continental fitted around 25 years ago, is it time to look at complete replacement ?
All advice would be much apreciated, thanks.
