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.
- What is a condensing boiler?
- A condensing boiler works on the principle of recovering as much as possible of the waste heat which normally leaves through the flue of a conventional (non-condensing) boiler as water vapour. The best high efficiency condensing boilers convert more than 95% of their fuel into heat, compared to 78% for conventional types. Condensing boilers get their name because as they recapture the heat from the water vapour leaving through the flue, this water vapour condenses back to a liquid, or condensate as it is known.

- How easy is it to install a condensing boiler?
- Boilers vary in size and shape but most are designed for simplicity of installation. With space being such a premium many boilers are small enough to be fitted by one person into a kitchen cupboard, easily and with minimum disruption.
- How reliable are condensing boilers?
- Condensing boilers are reliable if well maintained and serviced regularly. A Which? survey in 2011 found that 46% of owners who bought a boiler after April 2005 have experienced some kind of fault. Not all of these faults required a repair. In fact the most frequent problem, a blocked drainage pipe, experienced by 11% of owners, is actually a problem caused by poor installation.
- Could a condensing boiler save money on my energy bill?
- Which? estimates that the average efficiency of boilers in UK homes is about 70%. This means they waste up to 30% of the heat they generate in the form of hot flue gases. This suggests that installing a condensing boiler, which has an efficiency of around 88%, can reasonably achieve savings of between £50 and £200 per year depending on the size of your house - and the saving will increase as the cost of gas increases.
