The average boiler lasts around 15 years. If you're ready for a replacement, you'll find most new boilers are condensing boilers (although there are some exceptions). Condensing boilers can save you energy and money. Depending on the efficiency rating of your boiler at the moment, a new condensing one could save you up to £305 a year*.
If you're not looking to fit a new boiler, don't forget to get yours serviced regularly. Some of our boiler cover products include a yearly boiler service.
If you're dealing with a faulty boiler, try our advice on common boiler problems and fixes. If you're not sure what your boiler issue is, we recommend getting a Gas Safe registered engineer to check. You might find you need a powerflush or magnetic filter for some central heating TLC.
What is an energy-efficient condensing boiler?
Gas boilers burn gas to create heat which produces waste gases. A non-condensing boiler gets rid of these waste gases via a flue. This isn't very efficient or good for the environment.
A condensing boiler works differently. It recycles the heat from these gases using a heat exchanger. So it reuses the burnt fuel which makes condensing boilers greener and more efficient than non-condensing boilers.
There are a number of different types of condensing boiler, such as combi, conventional and sealed systems. When choosing a boiler, make sure it gives you all the heat and hot water you need whilst still saving energy.
Advantages of condensing boilers
- More energy-efficient as they use more of the fuel for usable heat
- Lower energy bills
- Use less fuel than non-condensing boilers to produce same amount of heat and hot water
- Reduced CO2 emissions and carbon footprint
How efficient is your boiler?
SEDBUK is the energy efficiency rating system for boilers. It ranges from A (90% efficiency and above) to G (below 70% efficiency). A quick search online for your boiler's make and model should show you what its energy efficiency rating is.
What is the boiler scrappage scheme?
You may have heard about the government's boiler scrappage scheme. The original scheme closed in 2014, but you could still get help with energy-efficient home improvements including new A-rated boilers. Getting an energy-efficient boiler can help to reduce your energy bills and if you’re on a low income, you may be eligible for a discounted boiler installation.
