A condensing boiler is a lot more efficient than the previous boilers used throughout homes in the UK. But, how does it work, and is it worth it to upgrade? Here at K and M Maintenance, we know just how important boilers are within the home, and we know that condensing boilers are 100% worth it. This is our guide to all you need to know about condensing boilers.

How is a condensing boiler more efficient?

A modern boiler is a lot more efficient than older models, and one of the key reasons for this is the size of the heat exchanger. Taking away 90% of the wasted heat that is left over from burning the fuel, the heat exchanger recycles this heat back into the heating system instead of allowing it to become lost through the flue to the atmosphere. Ultimately, this leads to gasses that are much cooler than those within non-condensing boilers being sent out of the home through the flue, which can become cold enough to allow water vapour in the gas to condense, and then be recovered a second time. This improves the efficiency of the boiler even more, and ensure that your gas bills are lower.

Should I replace my boiler?

A boiler that is more than ten years old may be not as efficient as modern boilers produced today. In fact, a boiler of this age may be wasting 30% or more of the energy it is burning, leaving you to pay for more gas than you are actually using. This may not seem like a huge amount of wastage, but compared to a new, condensing boiler, your yearly gas bill total could be £300 more than it needs to be.

In summary

A condensing boiler makes use of a larger heat exchanger to recycle waste heat and energy from condensation to work at a much higher rate of efficiency than previous models. This can save you money on your gas bills as well as reduce emissions. If you have a boiler that needs replacing, why not contact the professionals at K and M Maintenance today?
