British Gas Boilers – All Shapes and Sizes
Wednesday, April 20th, 2011British Gas Boilers come in all shapes and sizes, as long as it’s gas!
That’s perhaps not surprising, as the UK’s biggest energy company is all about gas, although it does sell electricity to its customers as well. But British Gas boilers are basically available in three types: Combination Boiler, Regular Boiler and System Boiler.
Combination boilers are the most popular, because they suit modern, smaller dwellings that have maybe one, at most two bathrooms, and a medium sized central heating system. This is important because a Combination Boiler is all about supplying water when needed; on demand in other words. You turn on the hot water tap and out comes the water at the appropriate temperature. The central heating system signals it needs some hot water and, low and behold, the boiler turns on and provides the heated liquid.
Regular Boilers do all that of course, but in a slightly different way. It heats water and then stores it in a hot water tank for later use. In that case, it’s not hot water on demand, but stored for later use. And that makes a regular boiler slightly less efficient (doesn’t benefit from on demand principle which means that energy is only being expended when people, or the radiators need it) and more expensive (a hot water tank, as well as a header tank and more pipework are needed for a regular boiler).
A system boiler can be regarded as a modern version, more efficient version of a regular boiler system and is marked out by having all the key operating systems and controls all built into the boiler unit itself, which makes it cheaper and easier to install.
It’s the age of the Combination Boiler and when it comes to British Gas boilers, this is likely to stay the most popular type for many years to come.
