Posted By: jamesingramYes , but surely only in a well insulated home ( most UK home aren't ) in the heating season .Also in the summer its just going to waste
Posted By: jamesingramOur heating goes off at 10:00pm and comes on again at 0:9:00am. So while I'm sleeping the boiler is "pre-heating" this heat exchanger in case I might want hot water when I'm sleeping.On average it burns 2.8 units a night, and on cold winter nights its burning 3.5 uints (Cubic meters) This didn't sound like a lot till I converted it into How much does it cost on money.so 2.8 x 10.86 x 0.03675 x 365(day) = £407.89 that's just under a 1/3 of the bill for the entire year!
