Why Does My Boiler Make A Banging Noise When Firing Up

Nov 16, 2017 · If your boiler makes a single BANG when it fires up. You see, during normal operation, when a gas boiler receives the call for heat, the gas valve opens and releases a small amount of gas into a sealed combustion chamber via small “jets”. That gas is then ignited by the pilot light and the jet flames heat up a “heat exchanger”. That heat exchanger then is used to heat water.

Boiler Combustion Efficiency | HVAC Heating Systems

Efficiency is measured by dividing combustion losses, radiant heat losses from the jacket and near boiler piping, and unknown losses (losses from tube scaling, soot build-up (exchanger thermal efficiencies)) by total fuel input in BTU/h. Much of the efficiency is determined by combustion efficiency and a lot of maintenance departments focus on combustion efficiencies and ignore the other heat losses.

Condensing boiler - Wikipedia

One of the hot gases produced in the combustion process is water vapour (steam), which arises from burning the hydrogen content of the fuel. A condensing boiler extracts additional heat from the waste gases by condensing this water vapour to liquid water, thus recovering its latent heat of vaporization. A typical increase of efficiency can be as much as 10-12%.
