The most common fuel used in boilers is natural gas, followed by heating oil, and occasionally liquid petroleum gas ( LPG). Although rare, some boilers burn coal (usually in the form of coal pellets) or biomass (usually in the form of wood chips).
We specialise in oil-fired systems.
New oil boilers have to be of around 90% efficiency or higher (an A or B energy efficiency rating) and generally use condensing technology to achieve this. If your boiler is more than fifteen years old, you may want to consider replacing it with a new energy-efficient one.
What is the difference between a combi boiler and a conventional boiler?
Many people become confused between the term combination boiler & condensing boiler.
Combination boilers have the facility to heat instant hot water with no hot water cylinder required.
Condensing boilers are high efficiency boilers utilising high efficiency heat exchangers to gain this extra % in efficiency and in turn this means using less fuel to heat your home.
Modern boilers generally no longer have tanks in the loft to 'pressurise' the system through gravity. Instead they are sealed systems, and typically only require manual topping up from the mains water supply when the internal pressure has dropped. This is a simple operation that takes a few seconds, and involves opening a valve on a pipe below the boiler.
