I have a gas boiler and it's working fine and heating up the water for the storage tank. The pump also appears to be working ( can feel the whirring on the touch) Problem is the radiators are all cold, so what can be the problem?

In the cupboard wheere the hot water tank is, you will see a motorised valve fir the hot water, and one for the central heating. The valve for the heating is in the closed position.On the side of the valve you will see a lever which can be pushed to the "on" position, slide this lever as far as it will go and push it in to a little notch to keep it open. If your heating is working then, you need a new valve to replace the faulty one.If you have a programmer, check that first in case the heating is switched off there.

Without more specifics, its hard to tell what you have;
Your system might be air bound. go to the highest radiator in the house and see if there is a bleeder valve. Take a large cup or small bucket with you.
if you have the large cast-iron radiators, there should be a small valve on one of them thats piped into a 1/4" fitting. If you look at the top of the valve, there should be a slotted screwdriver fitting where you can open the valve. Hold the cup under the valve and let all the air out, until you get a small drop of water. Be careful, it could be loud, it could be a large amount of air, or it could be just a little bit.
Once you have all the air bled out of the system, you may need to add water to it.

You've probably got air in the radiators. Got to your local DIY store and buy a radiator key (cost about £2). On each of the radiators you will see a small square piece of metal (nut) either on the upper side or rear. Put your heating on. Use the key to turn these anti-clockwise until you hear air coming out (the air will smell bad, thats usual), as soon as water comes out lock the nut and move on to the next radiator. Do this to all of them, you may have to do it two or three times to get all the air out. Hold an old cloth underneath the nut to catch any water as you do it. Do this once a month to ensure your heating works fully. Good luck.

Maybe your two/three way value. normally near the pump. if broke will not switch to allow the pump to pump the water round your rads. try manually switching it. if that works will need replacing
If not maybe air in your rads. remember if you bleed your rads switch the heating off or your air will suck through your expansion pipe into your heating system.

It will probably be a faulty motor in a zone valve or three way valve. Could also be a faulty timer. BUT FIRST, check your room stat if you have one, it may be set too low as it's a bit milder now.

pump could be duff, or you have a major sludge / air problem. Finally, there could be an electronic valve which is stuck. Call in the experts, I fear.

your system may need to be flushed- try calling a professional because old radiator systems are dangerous to work on yourself
