Put simply, a condensing boiler is a water heater fueled by oil or gas. Its main purpose is to generate more heat from the waste gases which are usually lost with a non-condensing boiler. Let’s take a closer look at how a condensing boiler works and how much it costs to install one.

How do I know if I have a condensing boiler?

Condensing boiler regulations have been in place since April 2005, so any boiler installed after this date is most likely a condensing unit. The best way to check is to see if there is a plastic pipe sticking out of the closest external wall to where the boiler is installed.

How does a condensing boiler work?

With a non-condensing boiler, heat is wasted in the form of gases which are released from the flue. A condensing boiler, on the other hand, captures some of this heat and uses it to heat water returning from your central heating system. As a result, it is more efficient because it requires less heat from the burner.

Understanding condensing boiler costs

Condensing boilers are approximately 15 to 30% more energy-efficient than non-condensing units and can reach efficiencies of over 90%. In order to translate this into savings, the best way to think about this is to imagine that 100% represents every £1 being spent on your energy bills, so any percentage under that is a penny lost.

In regards to installing a condensing boiler, you can expect to pay between £1950 and £2190 to make the switch. Replacing a combi boiler with a condensing unit is usually more expensive than a regular system.
