Most of us think of central heating as a modern invention but it in fact dates back to a warm air system developed in Roman times. It wasn’t until the 1970s, however, that central heating fired by a gas boiler started to take off and by the early 1980s it was regarded as a basic requirement for UK homes.
Given that boilers account for about 60%* of a household’s annual energy costs, how efficient they are has a big effect on bills. With older gas boilers, a considerable amount of heat that could be used to generate heating and hot water is lost. Generally, the older they are, the more heat they lose, making them increasingly expensive to run.
In the last few years, new ‘condensing technology’ has been incorporated into boilers. Essentially this enables some of the heat that would otherwise escape from a boiler to be captured and re-used. As a standard rule the better the boiler quality, the more it captures. For example, some very old boilers can only achieve 60% efficiency and even relatively newer ones are much more efficient. We mainly work in West Sussex, Crawley, Horsham Brighton, Shoreham and across the South Coast.
