central heating help needed.

[kendra20]

can anyone help. my central heating boiler is working fine but although i have it full on only 2 out of 5 radiaters are getting hot i have blead them loads of times but it makes no difference, its not always the same ones yesterday the kitchen one was hot but not the living room now the kitchen one is cold so is the living room and bedroom but the hall one and bathroom are hot. the thermostate is on as high as it can go. so are all the radiators. i have phoned the help line of the manufacturers but they cant help till after xmas. please no silly answers im recovering from chemo and have got to keep warm.

Have you got thermostatic radiator valves on? - in which case the thermostats may be telling the rads that the room is actually the temperature it is supposed to be - and hence reducing the supply of hot water to the warm rooms.
Incidently bleeding rads in the vain hope it makes them warm is a futile exercise. The technique is only useful if there is a gas at the top, evidenced by a temperature gradient- cold top, warm base.

cant help kendra but best wishes too. I have a similar problem on a larger scale. I quite often get some radiators that fail to get hot one day and the next they can be boiling - they are thermostatically controlled, but one was in our downstairs loo and we kept the door shut and it was baltic in there, wouldn't heat at all. What I have found to work sometimes is to shut down the thermostats on the hot ones to force the heat into the the cold ones and when they get hot to turn the thermostats back on on them all. seems to work for a while. Only seem to get this problem when the weather gets really cold. The toilet radiator didn't respond to any of that treatment, but suddenly just started getting hot again!

Sounds a bit extreme to be the usual rad balancing problem kendra. Are the "hot" rads nearest to the boiler?
One rad might suggest a sludge build-up, but three?

thank you for your answer but we were told on the help line for the makers to bleed them all frequently the rooms are freezing so the temp isnt too hot
