Heating makes up about roughly 60 % products spent every year on energy bills, so a powerful boiler creates a appreciable difference.
Modern boilers are generally more potent for a lot of reasons, however key advantage is the fact they’re all condensing boilers. All well-maintained boilers use up their fuel efficiently, but they unavoidably lose some heat using the hot gases that escape the flue. A condensing boiler has a much larger heat exchanger, as a result it recovers more heat, sends cooler gases within the flue and is more effective.
Sometimes the flue gases end up getting so cool the water vapour inside of the gas condenses out (hence the name), and further energy is brought back in the condensing vapour.
What do i need to consider when replacing my boiler?
If it is time and energy to replace your boiler, you will need to consider which form of boiler is great for you. Below are a few issues to think about:
If you currently have mains gas, a gas boiler is most likely gonna represent probably the most cost-effective heating solution. Our fuel prices by March 2016 propose that an oil home heating system is already a much more cost-effective selection, nevertheless historically oil heating has always been more expensive.
If you don’t take advantage of a gas supply to your house, it could possibly perfectly be worth checking out akind of low carbon heating such as a heat pump or biomass. Combined with renewable heat incentive these could become more affordable over-all.
Alternatively you may desire to purchase a gas connection to your home. This company which owns and manages the gas network close to you will be able to help with the price tag on purchasing a new connection, and it also may possibly be completely funded.

Most older gas and oil boilers are normal boilers which could have a separate boiling water cylinder to hold boiling water, rather then supplying it direct coming from the boiler. When you replace your boiler you may buy a new regular boiler, and then keep the domestic hot water cylinder, or get yourself a combi boiler that doesn’t have to have a cylinder.
A typical boiler is more cost-efficient compared to a combi at making very hot water during the first instance, however some heat is displaced through the hot water cylinder, so a combi might actually be more efficient overall.
Your domestic hot water usage
Large families making use of a great deal of boiling water are most likely to generally be more satisfied having a regular boiler, whereas smaller families using less could be best off with a combi boiler.
Space in your house
Combi boilers don’t must have very hot water cylinders, therefore need less space as part of your property.
Compatibility with solar water heating
If you’re planning on installing solar water heating, it’s worth noting that a great many combi boilers aren’t compatible with this heating system orare not able to make use of it so efficiently.
