Heating accounts for about 60 % of what spent annually on energy bills, so an cost-efficient boiler would make an important difference.
Modern boilers are usually more cost-efficient for many different reasons, but their primary appeal is they are generally condensing boilers. All well-maintained boilers consume their fuel very efficiently, yet they inevitably lose some heat through the hot gases that escape the flue. A condensing boiler provides a much bigger heat exchanger, to ensure that it recovers more heat, sends cooler gases along the flue and it is more efficient.
Occasionally the flue gases end up receiving so cool which the water vapour in the gas condenses out (hence the name), and even more energy is recovered from the condensing vapour.
What must I consider when replacing my boiler?
Should it be time to change your boiler, you must determine the type of boiler is suitable to suit your needs. Here are various points to contemplate:
If you currently have mains gas, a gas boiler is extremely likely to be one of the most inexpensive heating solution. Our fuel prices by March 2016 imply that oil heating is at this point a more affordable choice, however historically oil heating has been more expensive.
If you don’t possess a gas supply to the property, it could possibly effectively be worth considering atype of low carbon heating for example a heat pump or biomass. Along with the renewable heat incentive these may be a little more affordable over-all.
As an alternative you can want to purchase a gas connection to your home. The company which owns and operates the gas network as part of your region might be able to help with the fee for having a new connection, also it may possibly be completely funded. Contact Energy Networks Association for extra information.
Most older gas and oil boilers are normal boilers that contain a standalone warm water cylinder to hold warm water, in lieu of offering it direct from your boiler. If you replace your boiler you are able to purchase a new regular boiler, and then keep your hot water cylinder, or get a combi boiler that doesn’t require a cylinder.
An ordinary boiler is way more reliable when compared to a combi at generating boiling water through the outset, and then some heat is displaced from the very hot water cylinder, therefore a combi might become more cost-efficient overall.
Your hot water usage
Large families using a great deal of boiling water usually are usually satisfied having a regular boiler, in contrast to smaller families using less may be more well off using a combi boiler.
Space in your home
Combi boilers don’t require domestic hot water cylinders, therefore demand less space in your house.
Compatibility with solar water heating
If you’re thinking about installing solar water heating, it’s worth noting that a majority of combi boilers aren’t compatible with this heating system orare unable to put it to use so effectively.
