The leading variants of central heating system
Before you purchase a central heating system you need to establish what type of system and heating boiler you will want. In this segment we will discuss that the variants of central heating system available to help you match them to your requirements. Most if not all of these Central Heating System comprise of a gas fired boiler, radiator and pipework.
Whether you are buying a new development or established household you’ll find that it will contain a central heating system which is a modern day necessity. 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 winter although most are also used to supply hot water every day of the year. Heating your home provides a relaxing and cosy ambience. In addition to warming the home the central heating system will be used to provide hot water when required. Your Central Heating System needs to be reliable. You will want an efficient system that operates in the background without any niggling breakdowns.
The primary variants of the central heating system are sealed systems and pumped systems.
The most frequent type is a pumped or vented system. A pumped or vented Central Heating System has a hot water cylinder and a feed and expansion tank. The tank makes way for any water expansion that is induced by the heating process. The tank is placed in the highest place in the house, normally the attic area.
As thinking develops sealed systems are now more commonly being installed in homes. Sealed systems have fewer parts having no need for the water expansion tank. A sealed Central Heating System gets its water direct from the water mains. if you adopt this system you don’t need to use your loft for housing in the expansion tank thereby saving space, the sealed nature of the system without any venting delivers a number of benefits:
- frozen winter copper piping from copper pipes in the attic it is now eliminated
- fewer components mean low buy costs
- less pipework and joints to leak
- you will get fewer problems from air ingress leading to corrosion or blocks
A pressure vessel is included in the system to deal with any pressure variations in the water supply. A escape valve will open if the pressure is higher than recommended. Similarly cold water is allowed into the system if the pressure is lower than the recommended level.
