What is a High Efficiency Gas Boiler?
High Efficiency Gas Boiler
A high efficiency gas boiler (HE boiler) is a type of boiler that is more efficient than a standard or average gas boiler.
In order to qualify as an HE boiler, the performance of the unit must meet certain criteria set forth by standards organizations such as the Building Research Establishment (BER) in the UK and other agencies worldwide.
High-efficiency gas boilers are also known as condensing boilers. What this means is that heat from the flue gases, which are typically at temperatures between 100°C and 150°C, is recovered and used to preheat cold water entering the boiler. In the majority of cases, this allows an additional 20% to 30% efficiency gain over a non-condensing boiler.
