Condensing vs Combi Boilers Explained | Boiler Gui

This meant that a significant amount of heat, and therefore money, was being wasted. To make boilers more energy efficient, condensing boilers were developed. Condensing boilers are fitted with 2 internal heat exchangers to ensure that less heat is lost. Thanks to this, the boiler doesn’t have to work as hard and uses less energy.

When you replace your boiler you can buy a new regular boiler, and keep your hot water cylinder, or buy a combi boiler that doesn't need a cylinder. A regular boiler is more efficient than a combi at producing hot water in the first place, but then some heat is lost from the hot water cylinder, so a combi may be more efficient overall.

The efficiency of modern condensing boilers comes partly from their ability to operate at low outputs during warmer weathers, hence why a low minimum output is so important. When your home requires just 1-2kW of heat, as it often does, a boiler than can only go down a low 7kW is going to be oversized for much of the year.
