Different Types Of Central Heating Systems

Gravity Fed Or Open Vent Central Heating System

The Gravity fed central heating system is considered the safest heating system as it does not involve any pressurized chambers. It has a very simple design which uses gravity to circulate water through the pipes.

It usually has two water storage tanks the bigger tank holds the cold water and the smaller tank the hot water. Gravity is used to push the water from the cold tank in to the hot water tank. Water is heated here with the help of a boiler and then this hot water is passed through the pipes which run through homes. The tanks are placed at a height thus gravity allows the water to be circulated through the pipes in the home.

Some places have a community tank where the municipality of the area is responsible for heating the water and then this water is distributed to the homes through the pipes. This is a much eco friendlier way of heating and also saves electricity as each home does not need a separate boiler to heat the water.

This water is in turn passed to radiators placed in room which exchange heat with its surrounding air. Warm air rises in the room and cold air settles at bottom as a result the cold air is reheated and thus this creates a cycle through which the air in the entire room is heated.

Combination Boilers

Combination boilers are popular with users around the world as everybody wants their water heated instantly. Combination boilers do not have a storage tank to store water. The combination boiler heats only the water which is required and thus makes it available for use. This also saves energy as heated water when not used can lose its heat while stored in the storage tank thus rendering it of no use.

Ground Source heat pumps

If you have ever touched the back of a refrigerator you must have noticed that it is hot to touch. A ground source heat pump works on a similar principle. They run cooling the surroundings of your home. Pipes which are buried in a trench around your home have a coolant running through it. These pipes are cooled using electricity and the heat thus generated is transferred to pipes that carry water around the home. This provides heat exchange in the rooms through the radiators while at the same time providing hot water for use at the tap.
