Selecting your next Central Heating System
Selecting your next Central Heating System
Central heating systems have developed and that there are now many different types each with differing benefits and disadvantages according to your requirements. To help you picture the choices available we will outline the main forms of system. When you purchase a central heating system you are essentially purchasing a collection of different parts including a central heating boiler and radiators.
In north Europe the primary household 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. Most existing houses and virtually all new home developments now incorporate central heating systems to heat the dwelling and provide hot water.
Try running a home without your central heating system switched on and you will quickly interpret how important the system is. Heating your family provides a restful and cosy ambience. Another important role for the central heating system is to create hot water. Dependability is a major requirement for your central heating system. You should find that your Central Heating System is safe, easy to use and long lasting.
You will find 2 main system variants, vented and sealed central heating systems.
The most familiar type of system is the pumped or vented system. A feed and expansion tank is incorporated into this form of central heating system alongside a hot water cylinder. The expansion tank allows the system to be topped up with water and creates space for the hot water to expand when the heating system is used. The attic is most commonly used to house the expansion tank as it needs to be high in the house.
If you purchase a new home you may now find that it incorporates a sealed central heating system. Sealed systems have fewer components having no need for the water expansion tank. The mains water is used to supply the sealed Central Heating System. if you adopt this system you don’t need to use your attic for housing in the expansion tank thereby saving space, you will get the following benefits when acquiring a sealed system:
- frozen wintertime pipework from copper pipes in the loft it is now eliminated
- no upkeep work on the tank or pipes that would be in the loft in a pumped or vented system
- reduces the risk of leaking
- you will get fewer problems from air ingress leading to corroding or blockages
Any water pressure variations are accommodated by the incorporation of a pressure vessel. If the pressure becomes too high in a sealed Central Heating System; a escape valve will permit water to escape from the system and if the pressure drops too low a valve will open to replenish the system with water.
