The hot water may be turned off to them or the valves could be clogged. Rust and sediment build up over time and stop the flow.

A hot water heating system (hydronic) uses heated water to circulate from a boiler to baseboard radiators or convectors, where the heat is wanted. This is done through a series of piping and pump(s) that move the heated water around. Warm air systems use a furnace to heat air and a fan to move the warm air through ducts to the point of use.

Your home heating system may use a furnace, boiler, electric resistance, hot water baseboard, radiant heat, geothermal or other system. Look through the phone book for a professional right away!
If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler
Hot water baseboard heating is called a Hydronic heating system.
Central heating systems usually heat on a different system from the hot water heater, unless the main heater is a combination furnace/hot water heater. If this is the case, it could be because the outflow of hot water is greater than the ability of the furnace to heat the water.
A radiator heating system.
The energy source is the same as for heating anything. Gas,Electricity, Burning any fossil fuel. in a boiler (furnace) with water running in heat exchanging coils or manifolds. When heat is needed a pump circulates the hot water through the radiators and back to the furness.
Forced air heating
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.
A Central Heating System is used to provide warmth to an entire building or portions of it. The heating is carried through vents or radiators connected by ducts or pipes.
