It depends on if you mean "domestic" hot water system or radiator heating system:
For a domestic hot water system, you might try the following:
open all the hot water faucets in the house and then shut them back off starting with the lowest after it stops spitting air and continue the same with all the others until you get to the highest faucet in the house (usually the kitchen faucet) once it starts putting out a steady stream of water you're all done.
For a hot-water radiator system, you should run the system to pressurize each heating zone, then use the bleeder valve on the top of the radiator, or somewhere on each loop, to let out the accumulated air. There are also automatic air vents that allow air out under pressure, but not water. A properly installed system should also have an air-venting system installed prior to the main circulator, as well as one or more "purging valves" to use when the system has been drained for repairs and refilled.
There will be a relief valve somewhere. This is the place to bleed off excess air.

What is the difference between a hot-water heating system and a warm-air heating system?
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.

How does air get into central heating or radiators?
Air ends up in hydronic (hot water heating) systems in the following ways:1. The system has just been installed or repaired, and it has been filled with fresh, air-laden water. Heating the water will purge the air, which then typically collects in high points. It will need to be purged out of the system.2. A leak in the system causes fresh water to refill the system (through the feedwater valve).3. Air migrates from the expansion tank (where it belongs) to one or more radiators (where it doesn't).We don't want air in the system because:a. the oxygen in it causes corrosion; andb. it blocks the flow of heating water.The way to repair the above problems is:for 1. -- to purge the air from bleed valves daily until no air remains.for 2. -- to locate and repair the leak, and then fill and purge.for 3. --to purge the system, and also empty the expansion tank of water.The HVAC Veteran
How do you get trapped air out of the heating system of a 2000 Pontiac Sunfire?
Purging the cooling system is a little involved, but isn't something that you can't do. Pick up a Haynes or Chilton manual and read the chapters about replacing the water pump and the thermostat. One or both of those chapters describe how to bleed air from the system.

Service the cooling system. Drain the coolant and replace the thermostat which is more than likely stuck open. Pour in a 50/50 mix of antifreeze and distilled water. Bleed all air from the system.
