The benefits of Condensing Boilers
Installing an efficient condensing boiler can save you significant amounts of carbon and money:
- Reduce your electricity bills: Condensing boilers are much more efficient in turning fuel into heat, so you need less fuel to heat your water and home, which can save you over £225 a year on your heating bills compared to a non-condensing boiler.
- Cut your carbon footprint: Because condensing boilers are more fuel efficient, they reduce your carbon emissions – replacing a G rated boiler will save 1,220 kg CO2 a year.
- Save space: Condensing combi boilers don’t need a hot water tank, saving you space.
- Simple controls: Condensing combi boilers don’t need timers for hot water as they produce hot water when you turn the tap on.
- 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.
- How often should I get my condensing boiler serviced?
- It's important to have any gas or oil fired appliance like a condensing boiler serviced once a year. The flue will need checking to make sure it is clear, and a qualified installer should check that your boiler is running safely and efficiently for you. It's best to check with your manufacturer about service schedules, as some boilers may need servicing more than others.
- 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 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.
