Boiler flow temperature for radiators
WebCombi boilers work best when they heat the water that goes to the radiators at 60°C or below (this is called the ‘flow temperature’). Most boilers in the UK are set at flow … WebSep 24, 2024 · Go to the radiator that you identified as the fastest to heat up, and turn the lockshield valve until it’s completely closed. Then open it by a quarter of a turn. 8. Take temperature readings. Once the radiator is hot, take a temperature reading where the pipework meets the floor or wall (on the lockshield valve side). Note this down.
