Hot water heating systems must be free of air to operate properly. The art of purging air from one of these systems comes with experience. There are usually purge setups in the piping, if the system was installed properly.
The purge setup will consist of one ball valve or gate valve and one boiler drain somewhere in the loop or zone.
There should be a half inch copper line connected to the water in the house that's used to fill the boiler and to purge air. This line will have an auto feeder valve somewhere between the tie into the water lines and the boiler.
There is a lever on top of the auto feed valve. This lever is to override the automatic setting that keeps the boiler at the right pressure. When lifted up the lever allows city water pressure to be fed into the boiler.
When the lever is down the setting will be somewhere between 12 and 25 pounds. This safeguards the system in case of a leak somewhere. Water will be added automatically.
The way we purge the system is by hooking a hose to the boiler drain in the purge setup. Close the ball or gate valve and feed water through the system and out the boiler drain. The ball valve is to make sure the water we're putting in goes through the entire system before exiting.
After the hose is hooked up and opened and the ball valve is closed, lift the lever on the automatic feeder and force city water into the boiler, around the loop your purging and out the hose.
Be sure to watch the pressure gauge on the boiler and never exceed twenty five pounds. You will set off the pressure relief valve at 30 pounds. This is why the hose must be opened before the lever is lifted on the auto feeder.
Put the hose end into a five gallon bucket and watch for air bubbles. Once the air bubbles have subsided, allow the system to purge for a few more minutes.
Close the lever on the auto feeder and then the boiler drain. Open the ball valve and you're done.

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.

Where does the heating process begin in a hot water heater system?
the boiler.
How many gallons of water does a hot water heating system use?
It uses as many as you run through it, but who would want to heat hot water?
Another name for a hot water heating system is a?
Hot water baseboard heating is called a Hydronic heating system.
How do you safely fill and purge a hydronic -- hot water baseboard -- heating system?
previous answer is typical. Hire a PLUMBER!!
How hot should the water be in a hot water baseboard heat system?
About 150 deg.
who can repair my home heating system?
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!

How do you compare a hot water heating system with a warm air heating system?
It gets hotter and hotter
Why do only some radiators heat on oil furnace baseboard heating system?
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.

Can a water heater be used to supply water to baseboard heating?
Yes. You might want to check to see what recommended temperature is for water entering the baseboard units and insure the water heater will meet that. Something else to consider is that there will need to be a pump in the water circuit to circulate the water. A tank type water heater would also work to store hot water until needed by the baseboard units in an instance where heat might be generated at a time not needed by the baseboard units.
What is a hot water heating system?
A solar hot water heating system is a method of supplementing the heating of hot water. The system uses either flat plate collectors or evacuated tube collector to harness the radiation from the sun to heat a fluid circulating through the collectors and subsequently an additional low level coil in a hot water storage vessel. This form of heating hot water must be supplemented by an additional heat source to ensure the hot water temperature is raised sufficiently to reduce the risk of bacterial growth within the hot water storage vessel. In the UK, solar hot water heating can provide on avaerage around 50-60% of the total hot water heating requirement when averaged over the course of a year.
