The pump is probably off if it`s a hot water system.
We use natural gas from a main supply, feeding a central heating boiler. This supplies hot water and water filled radiators throughout the house. The boiler is rated at 80,000 BTU/hour. We also have a gas supplied fireplace with artificial coals in the main sitting room, for the evenings in the winter.
1.Fan not working 2.obstructions in the duct system 3.coils are filthy and need to be cleaned
Turn up the inlet gas pressure on the furnace to create more BTUs.
If the air conditioner is on but not cooling the house properly, you may have a leak in your duct work. A leak would allow all of the cold air to escape, blowing into the outdoors instead of cooling your house.
Dirty air filter , bad fan motor,duct leakage under house,ice on coil.
A Worcester Combi Boiler is a gas powered boiler that heats water that pumps into radiators to warm the house. It also gives you hot water whenever you want it.
A boiler with a circulating pump and pipes to convey heating water around a house, through radiators or underfloor pipes.

Probably pockets of air in the plumbing. Do you have hot water radiators for home heating ? If so, you must bleed the air out of the units and the main boiler.
Put all the radiators on! SIMPLE!
There are too many different reasons. But it seems your unit outside is not working properly.
Try the thermostat, it may have accidentally been reset to a low temperature. Or the furnace (boiler) that supplies the heat may not be working. Or someone may have turned a valve to cut of the supply of heat to that part of the system. Withou tknowing whether you live in an apartment or your own house that's the best that I can suggest.
Gas heated hot water radiators.
I assume that you are referring to hot water radiators, heated by an oil furnace. These radiators could have air in them and will not allow the hot water to fill them and give off any heat. If these are connected to the same hot water line that feeds the other working radiators, the in and out lines and the bottom on the cold ones should be hot. These radiators will then have to have the air bled out of them. They should have a valve on the top somewhere to do this. If there is no heat in the lines there must be separate line to that room that is plugged or shut off.
On/Off valves in radiators turned off or clogged Another possibility is an air bubble in the loop that services the radiators that are not heating. Correction is to bleed the loop.
