Avon and Wiltshire Heating install 2 types of CONDENSING GAS BOILER SYSTEMS
1. CONDENSING COMBINATION BOILERS
Combination boilers are, by far, the simplest form of central heating systems available. Combination boilers are two appliances in one - a pressurised central heating boiler and an instantaneous water heater.
Benefits of a Combination Boiler for central heating systems
The main benefit of a combination boiler is that it heats water directly from the cold mains giving continuous hot water on demand to all taps at mains pressure with no need for any tanks. Water is only heated when required and is therefore usually more efficient and economical than a hot water storage cylinder which is part of a conventional system however, hot water will normally only flow from one tap at a time and heat flow to radiators is interrupted whilst hot water is being drawn.
2. CONDENSING BOILERS
With this type of system hot water cannot be provided on demand but must be stored, usually in a copper cylinder (usually located in an airing cupboard) and a cold water tank above it (usually in the attic) as well as a smaller central heating header tank (also usually in the attic).
As the water is pre-heated and stored, it can be used by more than one tap at a time without significant loss of flow. The Conventional system is particularly suited to the larger property with more than one bathroom or where mains water pressure is too low for an instantaneous appliance such as a combination boiler.
Most types of boiler are also available as high efficiency or "condensing" boilers. There are high efficiency combination boilers, system boilers, or conventional boilers. The term `condensing' or high efficiency applies to the technology which is used to maximise boiler efficiency to use less fuel for more heat.
Overview of a condensing boiler for central heating systems
Most types of boiler are also available as high efficiency boilers or condensing boilers. There are high efficiency combination boilers, system boilers, or conventional boilers. The term `condensing' or high efficiency applies to the technology which is used to maximise boiler efficiency to use less fuel for more heat.
A condensing boiler is a high efficiency modern boiler that incorporates either a larger heat exchanger or even a  second heat exchanger. It produces lower flue gas temperatures, lower flue gas emissions, and reduced fuel consumption. It typically converts more than 88% of the fuel used into useful heat, compared to, typically, 78% for modern conventional types.
By recovering and using heat that would otherwise be lost up the flue the best high efficiency boilers can operate with seasonal efficiencies in excess of 90%. Recovering the heat from the flue reduces the temperature of the flue gases to a point where water vapour produced during combustion is 'condensed out'. Thus the name, ‘high efficiency’ condensing boiler. A side effect is that this 'condensed out' water, known as condensate, which is usually acidic, has to be piped away to a drain or soakaway.
All condensing boilers will produce 'pluming' from the flue terminal which appears as steam. This pluming can drift into neighbouring properties causing annoyance and possible condensation on window glass or window frames so careful consideration should be given to siting the flue terminal especially if it might affect neighbouring properties.
