Heating makes up about around 60 % of your expenditure annually on energy bills, so an efficient boiler would make a appreciable difference.
Modern boilers tend to be more cost-efficient for many reasons, however their key benefit is always that they’re all condensing boilers. All well-managed boilers use up their fuel very efficiently, however they inevitably lose some energy inside the hot gases that escape within the flue. A condensing boiler features a larger sized heat exchanger, therefore it recovers more heat, directs cooler gases within the flue and its more effective.
From time to time the flue gases become so cool which the water vapour during the gas condenses out (hence the name), and substantially more energy is retrieved in the condensing vapour.
What can i take into consideration when replacing my boiler?
When it’s time to change your boiler, it is best to decide which kind of boiler is fantastic for you. Below are a few points to take into account:
In case you have mains gas, a gas boiler is most likely going to be the least expensive heating choice. Our fuel prices since March 2016 imply that an oil home heating system is presently a more affordable option, however historically oil heating has been more costly.
Should you not have a gas supply to the property, it might be worth thinking of avariety of low carbon heating for example a heat pump or biomass. In addition to the renewable heat incentive these may be cheaper over-all.
As an alternative you may desire to get yourself a gas connection to your home. This company which owns and manages the gas network close to you should certainly help with the price tag on having a new connection, plus it may maybe even be completely funded. Contact Energy Networks Association for even more information.
Most classic gas and oil boilers are common boilers that have a separate domestic hot water cylinder to hold domestic hot water, instead of delivering it straight from the boiler. As soon as you replace your boiler it can be easy to invest in a new regular boiler, and retain your hot water cylinder, or get a combi boiler that doesn’t need a cylinder.
A normal boiler is a lot more cost-efficient in comparison to a combi at producing warm water in the first instance, however some heat is displaced from the hot water cylinder, therefore a combi is much more cost-efficient overall.
Your very hot water usage
Large families using a great deal of boiling water could be best off using a regular boiler, as opposed to smaller families using less could possibly be best off with a combi boiler.
Space in your house
Combi boilers usually do not require hot water cylinders, therefore require less space in your house.
Compatibility with solar water heating
If you’re contemplating installing solar water heating, it’s worth noting that lots of combi boilers usually usually are not suitable for this home heating system orcan’t use it so effectively.
