Condensing Boilers

Condensing boilers are by far the most common boiler type in UK homes, and are far more energy-efficient than older mains gas boilers, using around 90% of their heat.

A condensing boiler works by passing hot gas through a central chamber that heats up water but, cleverly, a second chamber uses remaining heat to warm up water coming back into the unit from the heating system.
Of all the condensing boiler types, the combi-boiler is the most popular. A combi-boiler includes the hot water unit and cold water tank in the same unit, which means all your hot water and heating come from the same unit. This makes it easy to install.

It also means you get a steady supply of hot water through your taps as you don’t have to wait for the tank to fill and don’t have to worry about lots of space for different tanks. The downsides lie in the fact that, as they are a small unit, you will only get maximum pressure through one tap at a time, and they struggle to produce large quantities of hot water.

Heat-only boilers, in comparison, have a more traditional approach by offering hot water only, whilst cold water is supplied separately. This does away with some of the problems of supply and water pressure. But, because the hot- and cold-water systems are separate, they take up more space, and are less energy-efficient.
