Selecting your next Central Heating System

Central heating systems have improved and that there are now many different types each with differing advantages and drawbacks according to your needs. Below you will find an outline of the primary variants of central heating system presently traded. The type of central thinking system picked out will determine the type of boiler to be installed.

Due to the mean temperature that is experienced across the UK, Europe and in some parts of Russia, individuals barely find the need for air conditioning. Most existing houses and virtually all new dwelling developments now contain central heating systems to heat the home and provide hot water.

Whilst we tend to forget about the central heating system it will be operational day-to-day to supply hot water and comes to the fore in the wintertime when heating your dwelling house. You can relax at dwelling when the heating is functioning. A central heating system also delivers hot water for bathing and washing. For these reasons your central heating system has to be dependable. You will want an efficient system that runs in the background without any niggling breakdowns.

There are two primary types of Central Heating System; pumped or vented and sealed systems.

Expect to find a pumped/vented central heating system as they are the most common. A feed and expansion tank is incorporated into this form of central heating system alongside a hot water cylinder. In addition to allowing for water expansion when heated the expansion tank also tops up the central heating system with water when called for. The loft is most normally used to house the expansion tank as it needs to be high in the house.

A more modern option is a sealed system. The water expansion tank can be dispensed with in a sealed central heating system. A sealed Central Heating System gets its water direct from the water mains. The attic is not now used for the expansion tank or copper pipe work, seaing the system and removing the need to vent the hot water has some benefits:

- you don’t need to care about piping in the attic freezing

- there are fewer system component parts reducing any upkeep requirements

- less hazard of piping developing leaks

- as the system is sealed there is less chance of air incoming leading to corrosion or airlocks

Normal variations of pressure can be allowed in a sealed system through a pressure vessel that holds compressed gas. Valves allow cold water to enter and top up the system when pressure falls, other safety mechanics open valves if the inner pressure is to high.
