Wall mounted condensing boiler
The wall mounted condensing boiler does not just use the heat which
arises as the measureable temperature of the products of combustion,
but also the heat from the water vapour. This means that the wall
mounted condensing boiler has a particularly high efficiency.
Instantaneous water heater principle
The water is heated as it flows through the appliance. The maximum
draw-off rate is quickly available, i.e. without long waiting times or
interruptions for the heat-up process.
Operating pressure
The operating pressure is the pressure in the heating system.
Heating controller
The heating controller ensures the automatic control of the flow
temperature depending on the outside temperature (for weather-
compensated controllers) or of the room temperature in conjunction
with a time program.
CH return
The heating return is the pipework that returns the heating water at a
lower temperature from the heating surfaces to the appliance.
Heating flow connection
The heating flow is the pipework that supplies the heating water at a
higher temperature from the appliance to the heating surfaces.
Heating water
The heating water is the water used to fill the heating system.
Thermostatic valve
Thermostatic valves are mechanical temperature controllers that enable
a lower or higher heating water flow rate subject to ambient temperature
in order to maintain a constant temperature.
Siphon
The siphon is a stench trap for draining water that exits a pressure relief
valve.
Flow temperature
Flow temperature is the temperature with which the heated heating
water flows from the appliance to the radiators, underfloor heating
circuits, etc.
