Central Heating and the modulating boiler

To start with it all seems to make sense, the TRV measures the room temperature and controls the radiator temperature to suit, as the water flow is restricted the by-pass valve lifts, and hotter water is returned to boiler, so the boiler is throttled back (modulated) so the heat exchanger is cool enough to keep the flue gases below the critical temperature where moisture will condense out of it.

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency and carbon burnout. Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler.

What does it mean when a boiler can - Green Building Forum

1) Modulating occurs: If the boiler can modulate it will detect the high return temperature and turn the flame down, the return temperature reduces and the boiler stays in condensing mode. If the boiler cannot turn the flame down far enough it will start to cycle as well.
