Do not over radiate the system.
If the temperature of the coolant does not rise to the target temperature, the built coolant system is over radiating. This
means that there is a risk of condensation in the burner. Condensation water may cause soot and caulking into the
burner / heat exchanger.
Signs of the over radiation:
Coolant never reaches the target temperature and the heater power has remained 100%. E.g. target 55 °C
coolant temperature have raised to 45 °C but does not rise from that.
Exhaust leadthrough drips water
To prevent the over radiation:
Use 55 °C / 131 F normally-open-switches (thermostats) in matrix heater's fan motor power wire. It also saves power
when the fans do not run unpurposely when the coolant is not warm enough to heat the room.
Example of the normally-open-switch (thermostat) Installation example
Thermostats for the matrix heaters
Wallas room thermostat 2422 can be used to control the matrix heaters. Room thermostat switches the matrix heater
fans ON when needed.
Select the location of the room thermostat from the wall of the room, where the temperature is desired to be measured.
Do not install close to heat source or close to a window or door. Avoid locations that might be contacted by direct
sunlight.
