How old should your boiler be before you replace it?
If your boiler is more than 10 years old, you could benefit from installing a new condensing boiler. Because condensing boilers are more efficient than traditional boilers, installing one will save you £100-£300 on your annual heating bills. All new boilers installed must be condensing boilers that are A-banded for efficiency (at least 88% efficiency).
- 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 size should my condensing boiler be?
- The type and size of your new boiler will depend on a range of factors like the size of your property, how well it is insulated, and the type of fuel and heating system you use to heat your home. You installer will advise you on the type and size of boiler best suited to your property.
- 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.
