I have a 12 radiator system fired with a Merlin oil boiler 85,000 Btu's.
What would be the best settings, the room stat is in the hall and I dont have any TRV's. I want it to be nice & warm throughout. At the moment I have the room stat set at about 21 and the dial on the boiler at 75. It goes up to 90.
Is it better to set the boiler higher & let the room stat take over ?.
I want the best heat output at the cheapest running costs.
