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 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.
- If I buy a new boiler, does it have to be a condensing boiler?
- Yes. Government legislation now requires all new boilers to be the condensing type unless it would be impossible to fit one, which would probably be the case if there was no way to provide suitable drainage.
- 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.
