Heating accounts for about 60 % of what spent annually on energy bills, so a powerful boiler tends to have a substantial difference.
Modern boilers are far more reliable for several reasons, but their primary benefit is they are all condensing boilers. All well-managed boilers consume their fuel efficiently, yet they inevitably waste some heat through the hot gases that escape the flue. A condensing boiler has a bigger heat exchanger, as a result it recovers more heat, transmits cooler gases up the flue and is extremely effective.
Every so often the flue gases get so cool that the water vapour within the gas condenses out (hence the name), and more energy is recoverable from your condensing vapour.
What should i consider when replacing my boiler?
Should it be the best time for you to replace your boiler, you must work out which category of boiler is right for you. Here are a number of factors to take into consideration:
If you currently have mains gas, a gas boiler is in all probability going to be the cheapest heating choice. Our fuel prices at the time of March 2016 report that an oil heating system is currently a more affordable option, however historically oil heating continues to be more pricey.
In the event you don’t have a gas supply to the property, it may come to be worth bearing in mind akind of low carbon heating as an illustration a heat pump or biomass. In addition to the renewable heat incentive these may very well be cheaper overall.
Conversely you may want to acquire a gas connection to your house. The business that owns and manages the gas network inside your region may be able to assist with the fee for getting a new connection, and yes it could possibly also be completely funded.

Most classic gas and oil boilers are common boilers which may have a distinct very hot water cylinder to maintain hot water, as an alternative to delivering it direct from your boiler. After you replace your boiler you’ll be capable of obtain a new regular boiler, and continue to keep the domestic hot water cylinder, or have a combi boiler that doesn’t have to have a cylinder.
A normal boiler is a lot more cost-efficient in comparison to a combi at providing domestic hot water first of all, however some heat is displaced through the boiling water cylinder, so a combi may be more cost-efficient overall.
Your domestic hot water usage
Large families using a great deal of boiling water are most likely to generally be more content with an ordinary boiler, rather than smaller households using less could be best off using a combi boiler.
Space in your own home
Combi boilers don’t need hot water cylinders, and consequently need less space inside your residence.
Compatibility with solar water heating
If you’re taking a look at installing solar water heating, it’s noteworthy a large number of combi boilers aren’t appropriate for this heating system orcan’t utilize it so effectively.
