Can anyone suggest a practical way of directly measuring the flow rate in a central heating system.
My recently installed (Corgi installer) Worcester Greenstar 24Ri never heats the flow water to more than about 50degC., even though the temp. at the top of the aluminium casing on the heat cell is about 90deg!
The Worcester service guy tells me it's poor water circulation and says the boiler is fine.
Having had the system power flushed twice (the second time with a specialist powerflusher) and a new pump, I am told that there should be no problem with the circulation and the problem is with the boiler.
My installer is confused and so am I.
If there was some way of determining the the flow rate being achieved then it would clearly show where the problem was.
