Boiler systems can be powered by several different methods like gas, propane, oil and electricity. The boiler system is considered one of the most effiencet and cost effective method in home heating systems. The region you're located and availability of the heat source will have a play in which heat source is actually chosen.

Typically, boilers are of two types, water and steam. In the water boiler, the water is heated in the boiler then circulated through pipes by pumps. The hot water then causes a radiator to warm, giving off warm air in the room. Once the water cools, it is then pumped back to the boiler. The same principle is also applied to floor heating systems. The water is heated somewhere between 160 and 180 degrees Fahrenheit. The hot water boiler is considered more energy efficient and kinder to the pocket book. Additionally most agree the hot water boiler provides more even heat and provides for better health since the duct system and air blowers are not needed which cuts down on dust and pollens. In addition, they are quieter in operation.

The steam boilers are most often found in older homes. These steam boilers are powered by gas, oil or electricity. The boilers usually have pressure gauges and blow off valves to prevent explosions. The steam is created in the boiler and propelled through pipes to the radiator. As the steam cools, it turns to water and returns to the boiler. Many times when the steam first hits the pipes or is returning to the boiler as water you hear a hammering or banging. This is from the change in temperature of the pipes.

A relatively new type of boiler is the condensing boiler, which helps to reduce heat waste. They can convert up to 90 percent of its fuel to heat. Still using the water boiler, the condensing boiler provides for more energy efficient heat.

Choosing a system may depend upon what sort of heating is already in place. If a hot water boiler were already installed, it would probably be wise and save money to replace the system with another hot water boiler. Upgrading the system to a condensing boiler would be a safe bet and one proven to help improve those heating bills. After deciding which type of heating system to use, you have to consider the amount of space to be heated. Too small a system will not provide adequate heat. Install a system too large and heating cost will be higher.
