2020/2/1 · Once you've chosen between system or regular, you'll also need to think about the size of boiler to go for. This doesn't literally mean how big the unit is, but rather refers to its output. Your boiler output indicates how much power it has, and generally speaking, the more hot water and heat you require, the bigger the output you'll need.

By comparison, modern high-efficiency boilers have AFUE ratings between 90 and 98 percent, meaning as little as 2 percent of the energy is wasted. Condensing boilers are among the most efficient because they recycle the heat from water vapor in the system, so they require less energy to preheat cold water coming into the boiler.

In a condensing boiler, heat existing in the flue gasses can be captured and 'recycled' back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. This fall in temperature causes condensation, from which the name is
