Try making sure the valves are open, if they are sounds like they could have a air block, if so go to b&q, homebase or any diy shop and buy a radiator key and you will have to bleed them.
Good luck.

It sounds like the system hasn't been cleaned for a while, are they new or old rads, microbore or 15mm pipe.
First make sure that valves at both end of the radiator are open, it you thermal controls on the radiators make sure they are not sticking (WD40 job). Gentle taps around the pipe entry and exit may shift any hard deposit but this will only be a stopgap.
You may have to drain the system down, flush through with cleaner, run, flush through with fresh water then add a corrosion inhibitor. Here is the kind of stuff.... http://www.plumbworld.co.uk/93-0000
I know this is a pain but once done it should last a good while, it also helops protect the pump etc.
Also check that the air valve at the top of the boiler is sufficiently open to let trapped air out, this doesn't negate bleeding the radiators but it does reduce the amount of air trapped in the system.
If it is a sealed combi-system (most of them are) adding additives can be a pain as you have to drain the system down sufficiently to add the additives and then open a radiator and find a way of getting it in there and then re-pressurising your system.
Hope this helps. Here is a site that might help...

You let the air out of the radiators and THEN put the pressure back up? You have to keep pressure on so the water forces the air out until water dribbles out the bleed valve, then close it again. The only other thing I can think of is a waterlogged expansion tank, usually near the furnace. it occasionally needs to be drained or have air pumped in. But it sounds like water doesn't go all the way to the top of the radiarors and they need to be bled properly. If you shut off the water pressure and then opened the bleed valves, you let air INTO to the tops of the radiators. Try again with the pressure on, so the air gets forced out.

i had the same last yr with the same make of boiler, theres a valve in there that switch's from heating to water supply on demand ie when you turn on a hot tap, they will stick sometimes they can be free'ed off simply by having the heating turned on then repeatedly turn the hot tap on and off, if that dont work plumber needed had to replace mine in the end about £80 total

If none of these answers help and you've tried everything else you have something serious going on, some air trapped somewhere or in the tank. Get a plumber out or the furnace people that know what they're doing.
Hey! good for you JS just keep an eye out for gators and Palmetto Beatles

Pump has been idle during summer, check to see if it makes a noise. Put a screwdriver against it and listen like a doctor.
If no noise ,remove brass screw from end of pump, insert small screwdriver and give it a flidck either way, should work.

Maybe rads have been bled that much that hardly any special
fluid left in rads to warm up,they may need a top up,this is a job for you plumber,they will never warm up if thi is the cause.

a electric heater is an idea. just have to put it in a area that is away from every thing so it won't catch fire.just until you could get some one to look at your heating system

My friend is in a similar situation. She dons woolley cap and all, as if she were about to climb Everest. Forget about a dainty pink-blossomed nightie - she's quickly getting used to this new night-gear. Maybe you should buy an electric heater or two, at that.
