Did you know that 55% of what you spend on your energy bills per year is down to your boiler? Therefore an efficient boiler will make a big difference.
Modern boilers are very efficient due to numerous of reasons, however the main advantage is that they are all condensing boilers. Well-maintained boilers burn their fuel very efficiently but they can tend to lose heat in the hot gases that escape. A condensing boiler has a larger heat exchanger which means it recover more heat and lets cooler gases escape instead.
When the flue gasses get so cool that the water vapour in the gas condenses out – that’s how we get the name of a condensing boiler – more energy is then recovered from the condensing vapour.
How much will you save?
This comes down to the number of people living in your home and how much you use your boiler.
Using a high efficiency condensing boiler with heat controls you could save between £190 and £240 a year. If you install the correct heating controls, you could save up to 40% off your bills.
The average lifespan of a boiler is 10-15 years, choosing the correct heating system with a high efficiency condensing boiler and correct heating controls can make a substantial difference to your heating bills long after they’re paid for.
What boiler is right for you?
If you have mains gas, a gas boiler is usually the best route to take.
If you do not have a gas connection, it can be worthwhile getting one. The company that runs the gas network in your area will be your aim of contact for requesting tis and they may be able to help with the cost of getting a new connection or it may even be fully funded.
Many old gas and oil boilers are regular boilers which have a spate hot water cylinder to store your hot water rather than pushing it directly from the boiler. When replacing these types of boilers you can get a new regular boiler and keep your hot water cylinder or buy a combi boiler that doesn’t use a cylinder.
The difference between a combi and a regular with a water tank is the regular may be more efficient at producing a lot of hot water but then some heat is lost, leaving the combi more efficient overall.
Hot Water Usage
Large families using lots of water are more likely to be better off with a regular boiler, whereas smaller households will be benefit from a combi boiler with using less.
Space in Your Home
Combi boilers require less space in your home.
Thinking of Solar Water Heating?
Many combi boilers are not compatible with this heating system or cannot use it so effectively.
