Heating makes up about roughly 60 % of the things you may spend annually on energy bills, so an cost-efficient boiler tends to make a significant difference.
Modern boilers tend to be more reliable for a lot of reasons, however their key advantage is that they’re all condensing boilers. All well-maintained boilers use their fuel very efficiently, yet they inevitably lose some energy via the hot gases that escape up the flue. A condensing boiler incorporates a bigger heat exchanger, so that it recovers more heat, directs cooler gases within the flue and is better.
In some cases the flue gases end up getting so cool how the water vapour throughout the gas condenses out (hence the name), and other energy is recovered in the condensing vapour.
What must I consider when replacing my boiler?
When it is the proper time to change your boiler, you simply must decide what type of boiler is the best for you. Here are some factors to contemplate:
Should you possess mains gas, a gas boiler might be the most cost effective heating choice. Our fuel prices by March 2016 suggest that oil heating happens to be a more inexpensive option, nonetheless historically oil heating is definitely more pricey.
When you don’t reap the benefits of a gas supply to your home, it may possibly often be worth contemplating atype of low carbon heating for instance a heat pump or biomass. Along with the renewable heat incentive these could be cheaper over-all.
Alternatively you might want to have a gas link to your household. This company which owns and operates the gas network as part of your region might be able to assist with the expense of investing in a new connection, and it also could possibly also be fully funded.

Most older gas and oil boilers are regular boilers which may have a standalone warm water cylinder to maintain boiling water, as an alternative to offering it straight from the boiler. Whenever you replace your boiler you may buy a brand new regular boiler, and retain your hot water cylinder, or obtain a combi boiler that doesn’t possess a cylinder.
A regular boiler is much more reliable when compared to a combi at generating boiling water to begin with, but then some heat is lost in the warm water cylinder, so a combi might be more cost-efficient overall.
Your warm water usage
Large households using a great deal of domestic hot water could be more content having a regular boiler, unlike smaller households using less is much more satisfied developing a combi boiler.
Space in your house
Combi boilers don’t need hot water cylinders, and consequently demand less space within your residence.
Compatibility with solar water heating
If you’re checking out installing solar water heating, it’s worth noting that a great many combi boilers are not appropriate for this home heating system orare not able to utilize it so efficiently.
