Heating makes up about about 60 % of your own expenditure each and every year on energy bills, so a highly effective boiler makes a tremendous difference.
Modern boilers are generally more reliable for several reasons, but their major advantage is the fact that they're all condensing boilers. All well-managed boilers consume their fuel efficiently, nevertheless they inescapably waste some energy during the hot gases that escape up the flue. A condensing boiler has a larger sized heat exchanger, so that it recovers more heat, directs cooler gases the flue and is more potent.
Occasionally the flue gases get so cool that the water vapour within the gas condenses out (hence the name), and other energy is brought back in the condensing vapour.
What should i consider when replacing my boiler?
When it's the right time to change your boiler, you will need to figure out which type of boiler is designed for you. Here are a few points to consider:
If you currently have mains gas, a gas boiler might be the lowest priced heating option. Our fuel prices since March 2016 signify an oil home heating system is presently a less expensive option, alternatively historically oil heating has been more expensive.
When you don't really benefit from a gas supply for your property, it could well be worth considering avariety of low carbon heating for instance a heat pump or biomass. Combined with renewable heat incentive these may are more affordable overall.
As a replacement you may would rather get hold of a gas connection to your residence. The business that owns and manages the gas network with your region will be able to assist with the cost of getting a new connection, also it may perhaps even be fully funded. Contact Energy Networks Association for additional information.
Most old gas and oil boilers are regular boilers which could have a separate very hot water cylinder to store hot water, rather than supplying it direct in the boiler. After you replace your boiler you might get a new regular boiler, and make your boiling water cylinder, or purchase a combi boiler which doesn't require a cylinder.
A standard boiler is far more reliable compared to a combi at producing boiling water in the first place, then again some heat is lost from your boiling water cylinder, therefore a combi could possibly be more cost-efficient overall.
Your warm water usage
Large households using a lot of very hot water are likely to be best with a consistent boiler, whereas smaller families using less could be more satisfied employing a combi boiler.
Space in your home
Combi boilers don’t require boiling water cylinders, and so demand less space with your property.
Compatibility with solar water heating
If you’re choosing installing solar water heating, it’s worth noting that the majority of combi boilers usually are not appropriate for this home heating system orare not able to put it to use so effectively.
