Heating accounts for roughly 60 % of the expenditure annually on energy bills, so an reliable boiler makes a significant difference.
Modern boilers are more cost-efficient for a variety of reasons, but their principal advantage is they're all condensing boilers. All well-maintained boilers use their fuel very efficiently, yet they inescapably lose some energy via the hot gases which escape the flue. A condensing boiler incorporates a much bigger heat exchanger, so it recovers more heat, directs cooler gases in the flue which is extremely effective.
Sometimes the flue gases become so cool how the water vapour into the gas condenses out (hence the name), and substantially more energy is recoverable through the condensing vapour.
What do I need to keep in mind when replacing my boiler?
When it's the correct time and energy to replace your boiler, you should select which kind of boiler is right for you. Below are a few points to contemplate:
If you possess mains gas, a gas boiler is likely to be the smallest priced heating option. Our fuel prices as of March 2016 claim that an oil heating system is presently a less expensive choice, however historically oil heating has long been more expensive.
Unless you have got a gas supply to your property, it may well be worth considering atype of low carbon heating for example a heat pump or biomass. While using the renewable heat incentive these is much more inexpensive over-all.
Conversely you may decide to acquire a gas connection to your residence. The organization which owns and operates the gas network within your region may be able to help with the fee for getting a new connection, also it may possibly also be wholly funded.

Most classic gas and oil boilers are standard boilers that contain a standalone very hot water cylinder to hold boiling water, as an alternative to providing it straight from the boiler. Whenever you replace your boiler it is easy to invest in a new regular boiler, and then maintain your boiling water cylinder, or buy a combi boiler that doesn't need to have a cylinder.
An average boiler is a lot more reliable when compared to a combi at providing domestic hot water to start with, however some heat is lost through the domestic hot water cylinder, therefore a combi could possibly are more cost-efficient overall.
Your hot water usage
Large families making use of plenty of domestic hot water usually are often best with a normal boiler, instead of smaller households using less could possibly be more satisfied employing a combi boiler.
Space at home
Combi boilers don’t need to have boiling water cylinders, and consequently demand less space with your household.
Compatibility with solar water heating
If you’re pondering installing solar water heating, it’s worth noting a large number of combi boilers aren't suitable for this heating system orare not able to utilise it so effectively.
