Central heating systems

In the past, every room in a house had its own fireplace or stove. These days, most homes have a central heating system that uses hot water or hot air to distribute heat from a central heat source to the rest of the house. The central heating system may deliver heat through radiators, baseboard heaters, heating ducts or radiant floor systems. It can be powered by nearly any type of fuel. The most common are oil, mains gas, LPG and electricity.

There are two basic types of boilers used for central heating systems - conventional and combination boilers.

Conventional systems were the norm for most homes until the 1980s. They consist of one hot water storage tank and two cold water cisterns, usually in the roof space of the house. Conventional systems are considered ideal for large families, or if you have more than two bathrooms.

Combination boilers (or combis) make up the majority of new boilers installed in the UK. Unlike conventional systems, combi systems do not store hot water, but rather heat it as needed. The result is a highly efficient, space-saving heating system that is often less expensive to install and maintain.

In the last few years the regulations have changed and all new boilers whether conventional or combi are now condensing. Condensing boilers are highly efficient, converting about 90% of the fuel burned to usable heat.

In addition the new energy efficiency regulations state  in order to maximise efficiency more controlled should be given to the home owner which is achieved by installing Thermostatic Radiator Valves (TRVs) and a programmable room thermostat with additional timing capabilities for hot water.
