Heating accounts for roughly 60 % of your expenditure each and every year on energy bills, so a reliable boiler will make an important difference.
Modern boilers are considerably more efficient for a number of reasons, but their key benefit is that they're all condensing boilers. All well-managed boilers burn their fuel efficiently, nonetheless they inevitably lose some energy during the hot gases that escape within the flue. A condensing boiler possesses a bigger sized heat exchanger, so that it recovers more heat, transmits cooler gases the flue which is more efficient.
Every now and then the flue gases end up getting so cool which the water vapour throughout the gas condenses out (hence the name), and increasingly energy is reclaimed in the condensing vapour.

What must I consider when replacing my boiler?
Should it be time to modify your boiler, you must figure out which kind of boiler is appropriate for you. Here are some things to look at:
If you possess mains gas, a gas boiler is very more likely to represent the lowest priced heating solution. Our fuel prices by March 2016 signify an oil home heating system is presently a more affordable choice, on the other hand historically oil heating is definitely higher priced.
In the event you don't make use of a gas supply on your residence, it may adequately be worth taking into account atype of low carbon heating as an example a heat pump or biomass. Together with the renewable heat incentive these could be cheaper overall.
Conversely you might want to obtain a gas link with your dwelling. The company which owns and manages the gas network within your region may be able to help with the price tag on obtaining a new connection, and it can even be fully funded. Contact Energy Networks Association for extra information.
Most classic gas and oil boilers are standard boilers which could have a standalone domestic hot water cylinder to store warm water, in lieu of delivering it directly from the boiler. If you replace your boiler you can purchase a new regular boiler, and keep your domestic hot water cylinder, or purchase a combi boiler that doesn't have a cylinder.
A standard boiler is far more efficient over a combi at producing very hot water to begin with, but some heat is displaced through the very hot water cylinder, therefore a combi might be more effective overall.
Your domestic hot water usage
Large families using a lot of very hot water could be more satisfied creating a regular boiler, contrary to smaller households using less is often more satisfied employing a combi boiler.
Space in your home
Combi boilers never require boiling water cylinders, and consequently need less space with your property.
Compatibility with solar water heating
If you’re contemplating installing solar water heating, it’s worth noting that a majority of combi boilers aren't works with this heating system orcan't utilize it so efficiently.
