Welcome to this video let's see together the components of a sealed chamber gas boiler.
Let's start from the control panel, the user sees the control panel in which the three knobs are, let's see them together: the first knob is for the heating temperature adjustment and is always held at three quarters of the temperature, the second is the temperature adjustment of the hot water, which can be chosen according to its use, the third knob is for summer / winter selection.
Going forward we see that there is the thermohydrometer component in which it is possible to view the temperature and pressure of the water.
Here it is possible to unlock the boiler and then reset inside the boiler obviously there are two electronic boards the first electronic board is the main power supply, the second is for ignition and fault detection through the LEDs.
This is the three-way pressure switch valve and also called diverter valve. At its end we have the sanitary microswitch inside there is the pump circulation precedence microswitch next to the heating delivery pipe we have the ntc temperature probe and here we have the temperature limit probe (safety)
Going forward we have behind the sanitary plate exchanger that we see better here behind the hidden boiler we have an expansion tank which is this done with this shape.
Going forward we have the circulator also called pump, below we have the safety valve at 3 bar and below we have the famous boiler pressure filling tap which I will have to act to open it by unscrewing it counterclockwise and make sure that the pressure on the dial on the thermohydrometer is at 1 bar and a half.
Here we have put to show you the power supply and connection terminals to the chronothermostat or room thermostat, starting from the power supply board we have the two cables that connect with the ignition electrode placed on the burner, on the same we have the detection electrode from which it is possible to do flame detection.
In the upper part we have the primary heat exchanger, going higher we have the fan which extracts the fumes produced in the combustion chamber which will have to expel them into the atmosphere.We have connected the fumes safety pressure switch by means of two silicone rubber tubes.
