Hi.
I recently purchased a new home in the summer and firstly replaced all of the radiators apart from two vertical ones as the old ones were very old and grotty. My boiler is a glow worm ultracom2 30cxi which is 4 years old. Initially upstairs radiators were getting hot and downstairs cool. I have balanced the system the best I can and upstairs radiators are fairly warm. Downstairs are Luke warm with some slightly hotter. Even after two hours of operation they are not much better.
I had the heating on for four hours and it only raised the temperature in the room to 12 degrees from 7.
I have set the central heating temperature to 70 degrees and it appears to get up to temperature quickly then rapidly drops to 45-50 degrees and this is repeated frequently. I believe this is called short cycling.
My flow pipe at the boiler gets hot very fast but return pipe stays cool and gets Luke warm after an hour or so.
I have tried turning off all radiators and testing one at a time and they all get hot when used individually with all others turned off via the trv.
I have two young children and we are all fed up of living in a cold house. Any suggestions would be greatly appreciated.
