Gas Heating System Options

These days there is a choice of heating boiler forms to power your central heating system according to your family requirements. This page concentrates on the form of system available. When you buy a central heating system you are essentially buying a collection of different parts including a gas fired boiler and radiators.

In north Europe the main dwelling house system will be the heating system, although there is much talk of planetary warming at the moment there is little mass requirement for air conditioning systems. Whether you are looking at a completely new home or an established house one of the features you will need to investigate is its central heating system.

Whilst we tend to forget about the central heating system it will be operational daily to provide hot water and comes to the fore in the winter when heating your family. A new central heating system can give your household the atmosphere you are looking for. Another essential role for the central heating system is to create hot water. As heating and hot water are essentials your system needs to be reliable. You will want an efficient system that operates in the background without any niggling failures.

Whilst there are multiple forms the two main forms of system are vented and sealed systems.

Expect to find a pumped/vented central heating system as they are the most common. The main deviation you will see is that this form of heating system in addition to the hot water cylinder is that it has an expansion tank. Hot water expands and in this type of system courses back to the expansion tank. The loft is most usually used to house the expansion tank as it needs to be high in the house.

Sealed central heating systems are now more usually installed in new homes. There is no need for the water expansion tank if you choose to have a sealed central heating system installed. The mains water is used to supply the sealed Central Heating System. This removes the requirement for any copper piping or central heating water tanks in the loft, the sealed nature of the system without any venting delivers a number of benefits:

- you don’t need to worry about pipework in the attic freezing

- fewer parts mean low get costs

- reduces the risk of leaking

- the sealing of the system precludes air entering which could lead to interior corroding or the development of an air lock

Any water pressure variances are accommodated by the incorporation of a pressure vessel. Valves allow cold water to enter and top up the system when pressure falls, other safety mechanisms open valves if the interior pressure is to high.
