Hi all,
I have a couple of questions about boiler cycling and radiator balancing.
What I'm doing:
I'm balancing my radiators using two multimeters with thermal probes. I have one heat probe taped to the the pipe just below the lockshield and the other just below the wheelhead.
My setup:
The four upstairs radiators have TRVs fitted but for the sake of balancing I've removed the TRV heads. The boiler is an Ideal Classic RS 260 (non-condensing).
What's happening:
The boiler is firing for 3 minutes then resting for three minutes.As the boiler fires up then I've noticed that the temperature of water entering the radiator rises to about 62 degrees celcius then drops down to about 47 before going back up again. The emperature is constantly either rising or falling, even after the heating has been running for about 4 hours.
My two questions are:
Is this continual rise and fall in the temperature of the water entering the radiator normal? Or should the boiler be firing up for longer? -the central heating thermostat isn't satisfied at any point durnig this process.
and assuming it is normal operation:
Should I be trying to balance the radiators at the upper end of the temperature range inflow? Obviously the water leaving the radiator drops in temperature too but there is a short while when the in flow is at it's lowest that it is a degree cooler than the out flow.
