Choosing your next Central Heating System
These days there is a selection of gas fired boiler variants to power your central heating system according to your dwelling house needs. To help you picture the choices available we will outline the primary variants of system. When you purchase a central heating system you are essentially purchasing a collection of different constituents including a boiler and radiators.
Air conditioning systems are not yet a stock feature in households whereas every northern European dwelling house is built with a form of central heating. The bulk of new houses that are being built in this day and age are built with a Central Heating System.
The value of central heating systems is fully realised in wintertime although most are also used to furnish hot water every day of the year. You can relax at home when the heating is running. Another essential role for the central heating system is to create hot water. For these reasons your central heating system has to be reliable. Systems tend to last for fifteen years and you will want one that is both economic and dependable.
You will find two main system types, vented and sealed central heating systems.
Expect to find a pumped/vented central heating system as they are the most frequent. A feed and expansion tank is incorporated into this type of central heating system alongside a hot water cylinder. The tank makes way for any water expansion that is caused by the heating process. The expansion tank is positioned high up in the house typically in the loft.
As thinking develops sealed systems are now more usually being installed in homes. The water expansion tank can be dispensed with in a sealed central heating system. The mains water is used to supply the sealed Central Heating System. There are no tanks or copper piping in the attic, you get a range of advantages from the elimination of these constituents:
- you don’t need to worry about pipework in the attic freezing
- no maintenance work on the tank or pipes that would be in the attic in a pumped or vented system
- fewer leakages from pipework seals
- the sealing of the system prevents air entering which could lead to interior corroding or the development of an air lock
A pressure vessel is included in the system to deal with any pressure variations in the water supply. Valves allow cold water to enter and top up the system when pressure falls, other safety mechanisms open valves if the internal pressure is to high.
