Heating makes up about about 60 % of your own expenditure each year on energy bills, so an reliable boiler makes a significant difference.
Modern boilers are much more reliable for a number of reasons, but their significant appeal is the fact they're all condensing boilers. All well-managed boilers consume their fuel very efficiently, but they unavoidably lose some energy through the hot gases which escape up the flue. A condensing boiler possesses a bigger sized heat exchanger, thus it recovers more heat, directs cooler gases along the flue and is also better.
Occasionally the flue gases end up getting so cool how the water vapour around the gas condenses out (hence the name), and further energy is brought back coming from the condensing vapour.
What do i need to consider when replacing my boiler?
When it's enough time to replace your boiler, you should decide what type of boiler is right for you. Below are a few issues to contemplate:
If you have already mains gas, a gas boiler is likely being the most inexpensive heating solution. Our fuel prices since March 2016 would propose that oil heating has become a less expensive selection, nonetheless historically oil heating continues to be more costly.
Should you not possess a gas supply to your property, it may be worth investigating atype of low carbon heating such as a heat pump or biomass. Along with the renewable heat incentive these could be a little more inexpensive all round.
Conversely you should buy a gas link with your residence. The company that owns and runs the gas network in your own area will be able to aid in the price of acquiring a new connection, and it also could possibly even be fully funded. Contact Energy Networks Association for further information.
Most classic gas and oil boilers are standard boilers which have a standalone very hot water cylinder to save boiling water, as opposed to providing it direct in the boiler. If you replace your boiler you can purchase a fresh regular boiler, and retain your warm water cylinder, or acquire a combi boiler which doesn't need to have a cylinder.
A normal boiler is much more cost-efficient in comparison to a combi at providing hot water for starters, but a majority of heat is displaced through the hot water cylinder, so a combi can be more efficient overall.
Your hot water usage
Large families making use of a great deal of hot water could be more content creating a regular boiler, as opposed to smaller households using less might are more satisfied utilizing a combi boiler.
Space in your house
Combi boilers don’t need hot water cylinders, and therefore require less space in your property.
Compatibility with solar water heating
If you’re contemplating installing solar water heating, it’s noteworthy that a lot of combi boilers usually are not appropriate for this heating system orcan't make use of it so effectively.
