Alpha Printed Circuit Boards PCB Alpha 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 the …
Regin Electrodes & Leads Regin Electrode and Lead also known as monitoring or burner electrodes, boiler and plate electrode are used in many different ways and can be referred to as a Regin Spark or Ignition Electrode, these electrodes ignite the gas within the boiler when gas is first present within the combustion chamber. The Flame …
Chaffoteaux Control Knobs & Switches The Chaffoteaux control knob also known as selector switch, hot water switch, reset button, on/off button resides on one of the spindles located on the front of the appliance and allows the user to manually control certain aspects of the appliances operation. Some boilers allow you to change temperature and …
Alpha Fan Assemblys & Impellors Alpha Fan Assembly also known as exhaust fan, boiler fan, air fan is the part that injects fresh air into the combustion chamber, allowing the gas to be burnt correctly. It also extracts the toxic gas after the combustion process is complete. This device introduces fresh air into the combustion chamber, …
Chaffoteaux Central Heating Pumps Chaffoteaux 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 Chaffoteaux hot water pump or circulation pump. It …
Alpha Thermistors or NTC Sensors Alpha 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 …
Regin 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 Regin hot water pump or circulation pump. It ensures that the heat that is …
Ferroli 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 Ferroli automatic air vent opens or closes depending on the water level. These auto air vents also …
Chaffoteaux Diaphragms & Membranes Chaffoteaux Diaphragms are also known as Chaffoteaux membrane, hot water diaphragms, flow diaphragms and central heating diaphragms. it is a boiler part that is normally located within the diverter valve or hydraulic section of the boiler. Its main purpose is to move a pin that then operates a micro switch which …
Alpha Isolation Valves & Taps Alpha isolation valve also known as hot water tap, heating tap, flow and return valve, filling valve, gas valve, non return valve, 1 way valve can be found underneath your heating appliance and enables the user to control the flow of gas and water into the central heating system. These …
