Central Heating

Pump keeps running

My central heating pump is staying on all the time and my hot water is red hot. This is all happening even when my heating is turned off.

1 Answer from a MyBuilder Heating Engineer

get your wiring checked. usually pump keep running for extra 10 to 15 minutes over run to balance , check as well cylindre stat might be faulty and connected all the time which make your hot water very hot , if you have vented system check over heat pipe coming from the cylinder over the cold water tank .
