The efficiency of your boiler may not be something you pay much attention to, but is it costing you hundreds of pounds extra each year?
The efficiency of your boiler plays an important role in how well your boiler operates as well as the cost of your fuel bills. The higher the efficiency of your boiler, the lower your fuel costs. The Energy Saving Trust estimates that you could save up to £300 a year by replacing your old inefficient boiler with a new A-rated one.
Some things age well, like wine or cheese. Boilers, however boilers do not! The older your boiler gets, the less reliable and efficient it will become. The average household gas bills are between £750 - £1,000, depending on the size of your property, the age of your boiler and its efficiency. Most boilers currently operating in the UK are around 80% efficient, due to many of them being oversized and older. Boilers over 25 years old can be as little as 60% efficient, which really racks up the fuel bills. An energy efficient boiler can help you lower your heating bill considerably, and whilst it may seem like a large upfront cost, the money you save in the long-run is extremely worthwhile. At iHeat we also offer 2 years 0% interest finance deals, preventing such a large upfront cost.
