Heating accounts for about 60 percent of your own expenditure annually on energy bills, so a good boiler makes a massive difference.
Modern boilers will be more reliable for numerous reasons, but their significant advantage is that they're all condensing boilers. All well-managed boilers use their fuel efficiently, but they inescapably lose some energy via the hot gases that escape within the flue. A condensing boiler provides a bigger heat exchanger, because of this it recovers more heat, transmits cooler gases in the flue and its extremely effective.
Occasionally the flue gases become so cool that the water vapour inside the gas condenses out (hence the name), and even more energy is retrieved coming from the condensing vapour.
What do I need to take into account when replacing my boiler?
When it's time to replace your boiler, you will have to consider what type of boiler is best for you. Listed here are various considerations:
If you have already mains gas, a gas boiler is very more likely to represent the most affordable heating option. Our fuel prices at the time of March 2016 signify oil heating currently is a more inexpensive option, nonetheless historically oil heating is more expensive.
When you don't make use of a heating engineer in blackburn supply on your property, it will be worth bearing in mind avariety of low carbon heating much like a heat pump or biomass. Together with the renewable heat incentive these may are more cost-effective all round.
Conversely you may wish to get a gas link with your residence. The business which owns and manages the gas network inside your region must be able to aid in the expense of buying a new connection, plus it might even be completely funded. Contact Energy Networks Association for further information.
Most old gas and oil boilers are normal boilers which may have a standalone boiling water cylinder to maintain boiling water, instead of offering it direct in the boiler. When you replace your boiler it really is possible to get a new regular boiler, and retain your warm water cylinder, or purchase a combi boiler which doesn't possess a cylinder.
A regular boiler is much more reliable than a combi at producing hot water from the first instance, however some heat is displaced in the boiling water cylinder, so a combi can be far better overall.
Your hot water usage
Large families using lots of domestic hot water could be more well off having a regular boiler, whereas smaller families using less might be best off possessing a combi boiler.
Space at home
Combi boilers tend not to require boiling water cylinders, therefore need less space at home.
Compatibility with solar water heating
If you’re investigating installing solar water heating, it’s worth noting that many combi boilers usually are not suitable for this heating system orare not able to utilise it so efficiently.
