Central Heating Systems Explained.

All central heating systems are designed to keep you warm by heating water and pumping it around your home. This is achieved by a continuous loop of pipes to radiators.

There are two basic types of of heating i.e. the conventional system with heating only boiler and the combination boiler.

Conventional boilers can be floor standing, wall mounted or concealed in a fireplace opening behind a purpose designed gas fire (also known as a back boiler).
Combination boilers may be wall mounted or floor standing.
With the exception of back boilers, both systems are usually styled to complement other appliances such as washing machines etc.

Conventional central heating system and combination heating system

Conventional boilers tend to be smaller than combination systems because the latter invariably include other components such as a pump. Remember however, that any space saved by the conventional system is offset by the need for a storage cylinder.

Conventional heating systems require some means of allowing for the expansion of the water when it gets hot. Traditionally this has been a cistern n the roof space.
Combination boilers use a built-in 'expansion vessel', making the overall dimensions bigger but eliminating the risk of freezing in the roof space over winter.

Flue

All boilers require air for combustion and a flue to dispose of the carbon dioxide and water vapours. There are two types of flue - the chimney flue, and the room sealed flue.
Flued boilers usually draw air from the room, which may cause draughts. Room sealed boilers don't, making them more energy efficient. Modern room sealed boilers feature fan assisted flues, with the advantage of a much smaller terminal and greater freedom in the location / siting of the boiler and flu.

Energy Efficiency

We all realise that when fossil fuels (gas, oil, coal) burn they cause damaging greenhouse gases. Producing products that use less of these essential fuels and cause less damage to our environment, is at the top of our agenda along with customer care.
Replacing a boiler, which is over 15 years old with a new condensing boiler, will save over a third on your fuel bills and reduce emissions.
