Hi all, i have a cold radiator in the main bedroom which is the furthest away from the boiler. Naturally this will be the coldest, as i have the boiler heat set to the minimum. Therefore is it more cost effective to have the boiler temperature higher(this will heat up the problem bedroom), and the adjustable taps on the other radiators set to a lower temp? Or the temp lower on the boiler and the adjustable rad taps set to the highest setting.
Thanks in advance
