I've got a fairly new oil central heating system with usual 3 zones (water, downstairs, upstairs).
My question is whether I run the boiler for any 1 zone am I better off heating the water too? Basically wud the boiler run at 1 'speed' capable of heating all 3 zones but if not its just dumping energy or will it use less oil when only heating 1 zone?
Thx!
