Heating makes up about roughly 60 percent of your own expenditure annually on energy bills, so an reliable boiler makes a significant difference.
Modern boilers tend to be more cost-efficient for a lot of reasons, but their principal advantage is the fact that they’re all condensing boilers. All well-maintained boilers use their fuel very efficiently, yet they inescapably lose some energy through the hot gases which escape in the flue. A condensing boiler includes a much larger heat exchanger, in order that it recovers more heat, directs cooler gases the flue and is more potent.
Sometimes the flue gases become so cool which the water vapour inside the gas condenses out (hence the name), and substantially more energy is recoverable through the condensing vapour.

When it’s the appropriate a chance to replace your boiler, you ought to select which sort of boiler meets your needs. Here are a few points to contemplate:
Fuel variety
In the event you possess mains gas, a gas boiler will probably be the minimum priced heating option. Our fuel prices at the time of March 2016 advise that an oil heating system is presently a more affordable choice, however historically oil heating has been more expensive.
If you do not have a very gas supply on your property, it could perfectly be worth bearing in mind atype of low carbon heating for instance a heat pump or biomass. While using the renewable heat incentive these is much more inexpensive all round.
Conversely you may wish to have a gas connection to your residence. The business which owns and operates the gas network in your region may be able to assist with the expense of having a new connection, plus it might possibly be wholly funded. Contact Energy Networks Association for even more information.
Boiler type
Most classic gas and oil boilers are standard boilers which have a standalone domestic hot water cylinder to have domestic hot water, rather than providing it from the boiler. After you replace your boiler it is actually easy to obtain a new regular boiler, and continue to make your very hot water cylinder, or purchase a combi boiler that doesn’t call for a cylinder.
A typical boiler is a lot more reliable when compared to a combi at providing domestic hot water firstly, however some heat is lost from your domestic hot water cylinder, therefore a combi may possibly become more cost-efficient overall.
Your very hot water usage
Large families making use of a lot of hot water usually are generally best off with a typical boiler, rather than smaller households using less may be more satisfied using a combi boiler.
Space in your house
Combi boilers don’t must have hot water cylinders, and consequently demand less space inside your household.
Compatibility with solar water heating
If you’re thinking about installing solar water heating, it’s worth noting that lots of combi boilers aren’t appropriate for this home heating system orare not able to apply it so effectively.
