Dear all,
I have a few questions about balancing a CH system. I ahve looked at:
http://www.diydata.com/projects/centralheating/balancing/balancing.htm
1) It says to start on the rad nearest rad to boiler, does this mean the closest in feet and inches to the boiler or the first rad on the loop from the boiler?
2) It says:
Fit the radiator thermometers to the INLET and OUTLET pipes of the nearest radiator to the boiler. DO NOT fit them to the main flow and return pipes.
Switch on the central heating system.
Close the lockshield valve on the first radiator to almost closed, as the temperature of the systems comes up, gradually open up the valve until the temperature difference between the two thermometers is about 20°F (12°F).
I know the difference should be about 20°F, but what should the inlet pipe temp be?
3) I have TRV fitted on some of my rads, does this affect balancing of the system, as som of the lockshield valves have gone?
Thanks in advance
