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.

FAQs

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 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.
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.
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.
