Can any one answer the following question on the above boilers pump.
I noticed recently that the over run period seems to be getting constant pump switched on.
The HW runs fine and heats water no problem. The problem seems to be with the CH side.
The boiler fires o.k, pump cuts in, boiler goes up to room stats temp, boiler cuts off and pump over runs. After about 2 mins the boilers temp leds indicate 60 degrees and boiler fires back up again. The pump is running constantly and never switches off. So is this a feature of this type of boiler?
I've also noticed that the pump housing is getting very hot. Pressure on the guage is approximatley just over 1 bar when CH is running. I noticed that this has dropped down from 1,5 bar when the system was first installed 3 years ago.
Any advice would be appreciated .
Cheers
