I've been having problems whereby the boiler heats the rads ok but after a time will shut down the heating, cool then fire back up again. The flow pipe is hot at this point but the return is nearly always cool.
I thought it may be that the system needs balancing which I have tried to do but found another (related?) problem in that not all the rads are getting hot.
I've opened up all the lockshieds and fired up the boiler. It seems the system is split between the rads upstairs (same floor as the boiler) and downstairs. The upstairs all get hot and toasty quickly whilst downstairs the first two small rads get hot then the rest only get warm at best and one doesn't get warm at all as the boiler eventually turns off (flow and return hot hot)
The boiler is a Baxi 105e with 3 biggish double rads, 1 single big and 5 small rads.
Pump failing or something more serious? I opened up the screw on the pump and got a little woosh and a steady trickle of water.
