Heating accounts for approximately 60 % of what you take every year on energy bills, so an cost-efficient boiler will make a significant difference.
Modern boilers are usually extremely effective for several reasons, but their key advantage is they are all condensing boilers. All well-managed boilers burn their fuel very efficiently, yet they unavoidably waste some energy within the hot gases which escape up the flue. A condensing boiler comes with a bigger heat exchanger, thus it recovers more heat, sends cooler gases within the flue and is better.
Sometimes the flue gases end up getting so cool that the water vapour throughout the gas condenses out (hence the name), and all the more energy is reclaimed in the condensing vapour.
What must I consider when replacing my boiler?
If it is the best time to modify your boiler, you have to know what group of boiler is perfect for you. Here exist several points to contemplate:
Should you have mains gas, a gas boiler is in all likelihood the most inexpensive heating choice. Our fuel prices since March 2016 would report that oil heating is presently a less expensive choice, however historically oil heating is certainly more costly.
In case you don’t benefit from a gas supply to your household, it could well be worth bearing in mind akind of low carbon heating for example a heat pump or biomass. Using the renewable heat incentive these might be more cost-effective all round.
As a substitute you may wish to get a gas link with your residence. The business which owns and manages the gas network in your own area should certainly aid in the fee for buying a new connection, and it can even be wholly funded. Contact Energy Networks Association for even more information.
Most classic gas and oil boilers are ordinary boilers which have a different warm water cylinder to save boiling water, as opposed to offering it direct through the boiler. After you replace your boiler you can actually purchase a new regular boiler, and make your hot water cylinder, or invest in a combi boiler that doesn’t need to have a cylinder.
A typical boiler is much more reliable compared to a combi at producing very hot water from the beginning, however some heat is lost from your warm water cylinder, so a combi can be more cost-efficient overall.
Your boiling water usage
Large families working with many domestic hot water are likely to be more happy with a typical boiler, whereas smaller families using less could be more satisfied by using a combi boiler.
Space in your home
Combi boilers do not need warm water cylinders, and so need less space in your house.
Compatibility with solar water heating
If you’re considering installing solar water heating, it’s noteworthy that lots of combi boilers usually are not suitable for this home heating system orare struggling to utilize it so efficiently.
