Deciding on the ideal central heating boiler for your house.

Heating accounts for around 60 percent of what you spend annually on energy bills, so an reliable boiler tends to make a significant difference.

Modern boilers are far more reliable for various reasons, but their major advantage is that they're all condensing boilers. All well-maintained boilers use up their fuel very efficiently, but they inevitably waste some energy in the hot gases which escape up the flue. A condensing boiler possesses a larger sized heat exchanger, as a result it recovers more heat, sends cooler gases up the flue and is more efficient.

Occasionally the flue gases end up getting so cool that the water vapour within the gas condenses out (hence the name), and a lot more energy is recoverable from the condensing vapour.

What do I need to take into account when replacing my boiler?

When it's the right time to change your boiler, you have to figure out what type of boiler is appropriate for you. Here are various points to contemplate:
Fuel type

If you have mains gas, a gas boiler is in all likelihood going to represent the most cost-effective heating choice. Our fuel prices as of March 2016 imply that oil heating is at the moment a more cost-effective selection, nonetheless historically oil heating has been more pricey.

If you don't benefit from a gas supply to your residence, it may very well be worth looking at atype of low carbon heating for instance a heat pump or biomass. With the renewable heat incentive these can be more cost-effective overall.

Alternatively you may want to acquire a gas connection to your residence. The company which owns and runs the gas network in your region may be able to assist with the expense of buying a new connection, and it might even be wholly funded. Contact Energy Networks Association for further information.

Boiler type

Most older gas and oil boilers are ordinary boilers which have a separate hot water cylinder to store hot water, as opposed to delivering it directly from the boiler. When you replace your boiler it is possible to buy a new regular boiler, and keep your hot water cylinder, or purchase a combi boiler that doesn't have a cylinder.

A normal boiler is much more cost-efficient when compared to a combi at generating hot water from the outset, however some heat is lost from the hot water cylinder, therefore a combi might be more cost-efficient overall.

Your hot water usage

Large households making use of lots of hot water are likely to be more content with a regular boiler, whereas smaller households using less may be best off having a combi boiler.

Space in your home

Combi boilers don’t need hot water cylinders, and so need less space in your residence.

Compatibility with solar water heating

If you’re thinking of installing solar water heating, it’s noteworthy that many combi boilers are not compatible with this heating system orcan't use it so effectively.
