How do you choose between a gas, oil and LPG condensing boiler?

Condensing boilers can be fuelled by gas, oil or LPG. If you can get a gas boiler installed, this is ideal, as gas is the cheapest fuel. If you cannot or do not want to be connected to the gas network, you can opt for an LPG or oil system instead.

FAQs

Is a combination condensing boiler more efficient than a regular condensing boiler?
A combination (Combi) condensing boiler can be more efficient than a standard condensing boiler because it heats water as you need it. Combi boilers are most suitable for smaller homes, as they can only keep up with a certain level of demand. Non-combi boilers produce hot water and then store it in a cylinder for use as and when. This is still quite an efficient process - but if the hot water is not used immediately, then inevitably some heat will be wasted. It will generally depend on the size and amount of hot water you're likely to need. You installer will be able to advise you which type of boiler best suits your needs.
What does the Sedbuk efficiency rating mean?
Sedbuk stands for 'seasonal efficiency of a domestic boiler in the UK' and is now given as a percentage score. This score is an estimate of efficiency when the boiler is installed under typical conditions in Britain, taking into account climate, housing conditions, occupancy patterns, and controls.
How is the Sedbuk rating calculated?
The 'seasonal efficiency of a domestic boiler in the UK' (Sedbuk) rating for boilers is calculated from the results of standard laboratory tests, together with other important factors such as boiler type and the kind of fuel used. It describes the boiler's efficiency.
