Best Condensing Boilers - 2021 Guide to Costs & Benefits

Feb 01, 2021 · Just as with older types of systems, the condensing boiler burns gas to be able to heat the water. This then produces both carbon dioxide and water vapour. The larger heat exchanger in the condensing boiler allows it to recycle the heat within the gases which would otherwise be completely lost through the flue to outside of the home.

PG Heat Exchanger for condensing boilers - YouTube

Nov 16, 2018 · Now if we can create condensing within a boiler heat exchanger, that's a lot of potential energy to be absorbed. It's also worth noting, on a factual basis, that this is not 'free' energy, this was energy that was within the gas but not transformed into heat during the combustion process.

Heat exchanger for an indirect water heater, powered by …

Condensing gas combi boilers used to have two heat exchangers, as it's thought that this was more efficient. To begin with, the water was heated in the primary exchanger. As hot waste gases were produced, the water that returned from its circuit around the radiators was pushed into the secondary heat exchanger, which only used waste gas to heat the water.
