02-12-2019· Condensing boilers work similarly to a conventional boiler in a lot of ways. In the end, the important differences come down to getting high-efficiency boilers vs. standard ones. Condensing boilers are much more efficient in energy use and maintenance, but are also more expensive to buy.

13-08-2018· Condensing boilers produce heat by burning natural gas or propane fuel. The word “condensing” refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler.

A condensing boiler is a boiler that collects any heat that would be lost through the flue, unlike older systems any excess heat that went through the flue would be lost which then reduces the overall efficiency of the system.

As well as having heat content, the condensate is basically distilled water, which is ideal for use as boiler feedwater. An efficient steam system will collect this condensate and either return it to a deaerator, a boiler feedtank, or use it in another process.

Condensing Boilers Condensing boilers typically extract over 90% of the heat from the fuel they burn, making them both cost effective and energy efficient. They are so effective because they extract heat from flue gases which would have otherwise been lost by a non-condensing boiler.

Condensing boilers are designed to provide homeowners with a highly efficient way of heating their home. Manufactured to generate effective heating with minimum fuel usage, these boilers could help you save up to £200 on your annual energy bill**. At HomeServe, all of the boilers we install are condensing.
