Hi,
It states in my boiler manual that the ideal boiler flow temp is 55c. But I can't seem to find a reliable way to measure this. I have a digital laser thermometer. When I point this at the 22mm copper pipes under the boiler ( the flow and return ) they never read more than 35c yet if I measure the surface temp on the radiator closest to the boiler it reads 66c.
Please , has someone got areliable way to measure flow temp ?
Cheers
