a short video explaining briefly how a combination boiler (combi boiler) works .
split up into 4 parts
the gas side (gas valve, fan , electrodes , burner)
the heating side (pump/circulator, main heat exchanger, expansion vessel, PRV/safety valve)
the hot water (diverter valve, flow switch/hall effect sensor, plate heat exchanger)
the electrics (PCB/printed circuit board, sensors/thermistors, thermostat and mains wiring)
I hope this helps anybody wanting to learn about central heating and gas boilers.
this was filmed in a #baxi BAXI 830 combi #combiboiler
