Do you require a vented or a sealed heating system
Buying a new central heating system is not a plain affair, you first should know what type of system is best suited to your household. To help you interpret the choices available we will outline the main variants of system. Most if not all of these Central Heating System comprise of a boiler, radiator and pipe work.
In northern Europe the primary family system will be the heating system, although there is much talk of planetary warming at the moment there is little mass demand for air conditioning systems. Nowadays central heating systems are a feature in every modern household.
Heating is vital, especially in wintertime. Heating your household provides a restful and cosy ambience. The central heating system also can give you a cheap source of hot water. You need heating and hot water every day so you need a system that you can reckon upon. You should feel that your Central Heating System is safe, easy to use and long lasting.
There are two main types of Central Heating System; pumped or vented and sealed systems.
Expect to find a pumped or vented central heating system as they are the most common. This type of system has a feed and expansion tank in concert with a hot water cylinder. The tank makes way for any water expansion that is induced by the heating process. The loft is most normally used to house the expansion tank as it needs to be high in the house.
A slightly newer, more modern system that several people are choosing over a pumped or vented central heating system is a sealed system. The water expansion tank can be dispensed with in a sealed central heating system. A sealed Central Heating System is attached to the mains water supply to allow the removal of the water feed tank. if you adopt this system you don’t need to use your attic for housing in the expansion tank thereby saving space, seaing the system and removing the need to vent the hot water has some advantages:
- taking out the copper pipes from the loft withdraws any risk of them freezing
- no maintenance work on the tank or pipes that would be in the loft in a pumped or vented system
- reduces the risk of leaking
- reduced risk of air locks, corroding and sludge as there is not a chance of air being drawn down into the system through open vents as the system is sealed
Any water pressure variances are accommodated by the incorporation of a pressure vessel. This system has a valve that allows mains water to enter the system if the water pressure has degenerated. An alternative valve will open if the pressure is detected as being too high.
