Heating accounts for about 60 percent of what you spend every year on energy bills, so an efficient boiler tends to make a appreciable difference.
Modern boilers are a lot more cost-efficient for various reasons, but their principal benefit is that they are all condensing boilers. All well-maintained boilers use their fuel efficiently, however they inescapably waste some energy in the hot gases that escape up the flue. A condensing boiler has a much larger heat exchanger, thus it recovers more heat, sends cooler gases up the flue and is more efficient.
From time to time 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 recovered from the condensing vapour.
What should I factor in when replacing my boiler?
When it is the right time to replace your boiler, you ought to decide which type of Gas Engineer in Ashford is ideal for you. Here are various points to consider:
If you currently have mains gas, a gas boiler is most likely to represent the lowest priced heating choice. Our fuel prices as of March 2016 mean that oil heating is now a more cost-effective choice, however historically oil heating has long been more pricey.
If you do not have a gas supply to your home, it might be worth thinking about akind of low carbon heating such as a heat pump or biomass. Using the renewable heat incentive it may be more affordable all round.
As an alternative you might prefer to get a gas connection to your property. The company that owns and operates the gas network within your area should be able to help with the expense of purchasing a new connection, and it may even be wholly funded. Contact Energy Networks Association for further information.
Most older gas and oil boilers are standard boilers that have a standalone hot water cylinder to keep hot water, as an alternative to providing it straight from the boiler. When you replace your boiler you may buy a new regular boiler, and retain your hot water cylinder, or buy a combi boiler which doesn’t need a cylinder.
A regular boiler is a lot more cost-efficient compared to a combi at producing hot water to start with, but some heat is lost from the hot water cylinder, therefore a combi could be more effective overall.
Your hot water usage
Large households using plenty of hot water are likely to be more satisfied with a regular boiler, in contrast to smaller families using less may be more satisfied with a combi boiler.
Space in your home
Combi boilers don’t need to have hot water cylinders, and therefore demand less space in your household.
Compatibility with solar water heating
If you’re thinking about installing solar water heating, it’s worth noting that many combi boilers usually are not compatible with this heating system orcan’t use it so efficiently.
