if i turn my system on constant or timed, it takes 2 hours to heat up the radiators. all the pipes around the boiler and tank are hot, and it is making a humming noise. the pilot light is burning and it seems to be making the right noises. the hot water is ok. the rrom thermostat is up to max and the thermostat on the tank is set to just over 60. why does it take so long for the heating to heat up? help would be appreciated before paying silly rates to a plumber....

Have tou checked your circulation pump. Also your rads may need bleeding. I am not a plumber, its just that I had this problem and was able to sort it.

Check that there is no air in every rad first, have you ever that the system flushed out. The pipe gets a build up in them that can half the diameter of the pipe if is really bad. Try the air first because to flush the system is not cheap.

The radiators need bleeding. You need to get a small bleed key and then you can do this yourself. Just undo plug a small amount and the air will come out. It is best to have a rag around the plug so that any water that comes out is contained.

Find your pump, coloured red, give it a sharp rap on the side with a small hammer when running, it sounds jammed failing that switch off heating, on the front of the pump you will find a screw about half an inch in diameter, unscrew, small amount of water will escape, inside hole you will find a slot for a medium size screwdriver ,insert driver and turn, this will free the armature if stuck, if solid and won't move then pump is u/s and will need to be replaced.

It could be two things, but I think it could be the latter. Your rads may be full of sludge, or your pump is not doing the job properly. If possible , increase the speed of your pump. If that doesn't make any difference, then I would recommend a new pump.

possibilities:
1. lockshield valves partially closed
2. thermostatic/wheelhead valves partially closed/jammed
3. motorised valve malfunctioning
4. pump malfunctioning (heating system working on gravity and convectional currents only)
cylinder stat shouldn't affect the heating unless it is wired back to front but 60 is a bit high and inefficient, try reducing it to 50.

could be air in the radiators,let air out with radiator key then make sure you top up water pressure to approx 1 8

maybe you need to bleed the radiators. air gets trapped inside after they have been off for a long time.
