Condensing natural gas boilers
So what is a condensing boiler?
To meet the requirements of the Kyoto Climate Change Convention 1997, the UK government has made a declaration of commitment to reduce greenhouse gas emissions by 12.5 per cent by 2008-2012. It has also voluntarily agreed to a 20 per cent reduction of carbon dioxide (COP2) by the year 2020. Carbon dioxide is one of the main products of combustion causing the greenhouse effect on the earth (global warming). There are many ways in which the government's energy target can be achieved but those that affect the building industry most are improved boiler efficiency.
Condensing boilers are the most energy efficient gas/oil boilers on the market today. They achieve this high level of efficiency by removing the heat from the carbon fuel it is burning and also cooling the products of combustion, which are normally wasted up the flue, so much so that the water vapour in them turns into liquid. This happens at around 55o C. For a boiler to cool the flue products this much it has to have a larger more efficient heat exchanger than traditional boilers. Water is one of the by-products of a condensing boiler and steps must be taken to dispose of it. The condensate needs to be discharged into either a drain or a soak away. Because relatively small quantities are produced at a time, all condensing boilers are designed to hold back the condensed water until, say, a litre is produced; this is variable depending on the size of the boiler.
There are three basic types of boilers:-
- Regular boilers - These are the most versatile boilers, they heat the primary water which can be diverted for your central heating and hot water requirements on an open vented or sealed system. They need a separate control pack (circulating pump, diverter valves, programmer, room and cylinder thermostats) and hot water cylinder. There is no restriction on the size of boiler that may be required. This boiler also has the ability to be adapted for solar energy heating.

A programmer can be inserted into the front control panel of the boiler making ease of installation and space saving. There is a limitation to the kilowatt output to these boilers. This boiler also has the ability to be adapted for solar energy heating.

There is no need for any cold water storage, or hot water tanks. They are suitable for properties with 1 bathroom, although there is a storage combination boiler available that would supply properties with 2 bathrooms. They are very efficient as they heat the water as you use it giving you increased pressure to your showers and hot water supply. Once again this boiler can also be adapted to accept solar energy heating and can be adapted easier than the other boilers mentioned above.

SEDBUK - Seasonal Efficiency of Domestic Boilers in the UK.
SEDBUK is a measure of the seasonal efficiency of a boiler installed in typical domestic conditions in the UK. The SEDBUK efficiency of most current and obsolete boilers can be found on the website www.boilers.org.uk.
We install a full range of boilers as listed below:-
The type of boiler, be it natural gas, LPG or oil, subject to your requirements, will be decided on a site survey.
