Main Auto Air Vents Main auto air vent (aav) The automatic air vent is a pressure safety device in the central heating unit. They work by using flotation to release accumulated air. As water flows through the heating/cooling system, a float within the Main automatic air vent opens or closes depending on the water level. …
Main Printed Circuit Boards and Relays Main Printed Circuit Board or PCB / Main Board / Electric board / Power board / Ignition board is located behind the user control section of the boiler. It runs and monitors the entire boiler ensuring it monitors all the temperatures, air flow pressures, water pressures, water flow within …
Main Central Heating Pumps Main Central Heating Pump also known as bronze pump, secondary pump, primary pump, grundfos pump, circulation pump is fitted inside the boiler to circulate water around the boiler, it also circulates water around the central heating system which is why it also called Main hot water pump or circulation pump. It …
Main Thermistors or NTC Sensors Main thermistor also known as heating sensors, water sensors, pressure sensors flow sensor, primary sensor or return sensor decreases circuit resistance as the temperature of the thermistor rises. The printed circuit board sends a current to the thermistor and can tell whether an increase or decrease in temperature is needed …
Main Expansion Vessels Main Expansion Vessels also known as expansion tank, air tank, built-in expansion vessels, 8 litre expansion in the boilers are to ensure that the pressure within the boiler operates within safe parameters normally between 1 to 2.5 bar. The expansion vessel should be half full of air and half full of water …
Main Gas Valves, Gas Solenoid Main Gas Valves also known as Gas solenoid, zero or 0 rate valve or modulating valve is fitted to the boiler to ensure that gas is delivered to the burner safely. This part is fitted internally to Main boilers and its primary function is to regulate the supply (flow) of Natural Gas or LPG …
Main Heat Exchangers Main Heat Exchanger is also known as the primary, secondary or dual heat exchanger, condensing unit , hot water Heat Exchangers or Main heat engine allows all the heat from the burner to transfer to the central heating water safely. It sits at the top of the boiler in non-condensing boilers and …
