The radiators upstairs do get warm when the system is turned on.The boiler too is upstairs

You may need to 'bleed' them. Get a radiator key (can be bought from diy stores ie B&Q) then bleed the radiators until water comes out, then turn it off. This works most of the time. The site below will give you info on how to do this.

As others have already suggested, bleeding would be the first course of action. However, you have to determine if the system has an automatic water replenishment valve, or if you have to do it manually.
If you are unfamiliar with plumbing, there is an easy way. Before you do anything, and with the system off, look at the pressure gage and make a note of the reading. Bleed you first radiator. Then come back and check the gage. If the pressure was maintained, you have an automatic valve and can continue on with the rest of the radiators without further attention to the gage.
If it does not recover, you might want to consider having a professional assist you. City water is often higher than what the boiler manufacturer recommends. (Arguably there's a safety pressure release valve.) i.e. most system run 10 to 15 PSI, while city water can be 30 to 60 PSI.

If you still have a problem after bleeding the air out, Then turn your radiators upstairs off at both ends. Turn on your boiler and if the downstairs rads heat up, leave it for an hour and turn on rads upstairs until you feel heat on them. Don't open the valves fully, but just enough to get the rads warm. Then check downstairs again.

Assuming you have bled them and they are full of water, (don't use an allen key it won't fit). It may be that you have serious sludge problem which has accumulated in the lower part of the system, or for some reason the system is not balanced properly, ie the radiator guard valves are at the wrong setting, if somebody has fiddled with them, if not then leave well alone, suggest the whole system needs draining and flushing

Check the water pressure on the boiler, if it's ok, justs needs bleeding. I had the same problem, but found out by chance, that we had a crack in the t-bar pipe upstairs. Now we're nice and warm.

Is the boiler upstairs or downstairs, could be the pump. Have the rads got thermostatic valves on them, check there settings. Have you got a room stat down stairs in a heated part of the house, could this be cutting of heating before upstairs rads get chance to heat up.

You could try bleeding them first with an alan key. If this does not achieve the desired result, then you need a heating engineer to look at the boiler.

Ours did the same thing, it turned out they just needed bleeding because there was air in the system. I think you can get a tool to do it yourself, probably at B&Q or somewhere like that.

You could check there is no air in the system by bleeding it. Also it maybe a problem with the pump.
With both things if you are unsure it's best to get someone in to check our for you as both could be costly if you don't ge them right.

have you tried bleeding them, normally if you open the little valve at the side of the radiators & let some air out they should heat up
