Heating makes up about roughly 60 % of your expenditure annually on energy bills, so a powerful boiler makes a significant difference.
Modern boilers are considerably more reliable for most reasons, however their primary advantage is that they are condensing boilers. All well-managed boilers use their fuel very efficiently, yet they inevitably waste some energy through the hot gases that escape within the flue. A condensing boiler has a bigger heat exchanger, as a result it recovers more heat, sends cooler gases the flue and its more effective.
Sometimes the flue gases get so cool that this water vapour into the gas condenses out (hence the name), and substantially more energy is brought back from the condensing vapour.
What ought i take into account when replacing my boiler?
When it is the proper time to change your boiler, you will need to determine what sort of boiler is perfect for you. Below are a few issues to look at:
If you have already mains gas, a gas boiler is likely to get the lowest priced heating choice. Our fuel prices by March 2016 mean that an oil heating system is at the moment a less expensive selection, nevertheless historically oil heating has long been more costly.
In the event you don’t reap the benefits of a gas supply for your residence, it may well come to be worth looking at aform of low carbon heating for example a heat pump or biomass. Together with the renewable heat incentive these could be cheaper overall.
As a substitute you could possibly prefer to have a gas connection to your property. The organization that owns and runs the gas network in your region will be able to help with the cost of receiving a new connection, also it may possibly even be fully funded.

Most older gas and oil boilers are normal boilers which could have a separate hot water cylinder to keep warm water, rather then providing it directly from the boiler. When you replace your boiler you’ll have the capacity to purchase a new regular boiler, and make your very hot water cylinder, or have a combi boiler which doesn’t demand a cylinder.
A typical boiler is much more efficient when compared with a combi at generating hot water to start with, however some heat is lost coming from the very hot water cylinder, therefore a combi is much more effective overall.
Your hot water usage
Large families using a lot of warm water are likely to become more satisfied developing a regular boiler, instead of smaller families using less could be best off employing a combi boiler.
Space in your own home
Combi boilers don’t require hot water cylinders, and consequently require less space at home.
Compatibility with solar water heating
If you’re planning on installing solar water heating, it’s noteworthy that a great many combi boilers will not be suitable for this home heating system orcan’t use it so effectively.
