Cost of replacing back boiler with combi – the best option for long term cost saving
A new combi boiler on its own costs between £500 and £2,000 depending on which make and model you choose. The main thing to decide upon when choosing a new combi boiler is to ensure that it is suitable for your home.
If you have a large home with high hot water demand and a large central heating system then you may want to consider a system boiler. The new boiler cost is about the same.
Replacing back boilers with a system boiler or regular boiler
If you do have a large home with high hot water demand then a combi boiler may not be the best for you. If you have a back boiler, you may already have a hot water cylinder that was used to store hot water. System boilers and regular boilers work similar so if the hot water tank is usable you could install one of these types of boilers instead.
Removing back boilers for modern boilers
Modern boilers are gas condensing boilers. This means that they are at least 90% efficient. The condensing part of the boiler ensures that any waste fuel is recirculated back around the condensing boiler to be used up. A modern boiler will have an energy efficiency rating of A or above. A back boiler efficiency rating would be below G, which is the lowest rating possible.
How much can you save changing from a back boiler to a gas condensing boiler?
It is estimated that if you change an old inefficient boiler to a combi boiler that you can save up to £350 per year on your energy bills. If you take the cost of the boiler installation into account at around £3,000 then you will have made your money back in around 8 years.
This may sound a long time, but considering that you may have been paying £350 extra for 8 years you could have wasted £3,000.
