I have a combi boiler and radiators. The radiators seem to be hot for about 1 hour then cool down and then come back on every couple of hours for about 5 mins!! Is this right not sure wether to call someone out? Thanks.

I have a boiler, new by the way, plus two different thermostats for the house. First, make sure your radiators are not full of pressure, vacuum locked. Very carefully take a pliers or, adjustable spanner (depends on where you at) and slowly with a small pail under the release valve loosen the adjustable valve nut until water is seen coming out. This will come out until steam finally comes, then close the valve, or you'll get steamed.
Do this to all the radiators. Sometimes the highest radiator will be enough but, with your problem you may have a vacuum lock.
If this doesn't work try you supply tank, it may have a problem with it.
If all else fails call a service repairman. Good luck

Do two things 1. bleed the radiators (you'll need a little key especially for the top or bottom end of the radiator , then you turn it slowly which will allow any air to escape but once theres water coming out turn it tight again) 2. Check your thermostat (will probably be in the living room, make sure its a temperature to suit you) if all else fails you can alway check a plumbing and heating forum on the net .................. if i have a problem i just type it in the address bar and hopefully the exact sentence or there abouts pops up and you may find one like that .......good luck.

With a combi boiler is it possible that [at the boiler] your tap water temperature is set higher than your radiator/central heating temperature?
It could be that your boiler never cools down enough to make the diverter valve switch over.
It may be a long shot but try setting them both to the same temp, or even with the heating set a bit higher higher.
Good luck.

did you ever think about turning the thermostat higher up?... if you've tried that and does the same thing still, you may have air in your boiler, soon to follow this may be loud sounds if its not your thermostat. If youve got air in it with the loud banging sound theres an air bleed valve at the top of the boiler make sure you have a bucket handy as once the air is gone it'll be water. Also check to see if your hot water is working properly,

This is not normal, probably thermostat trouble. Check stat in hall or living room. If you are not familiar with boilers get a good friend in who knows.
