The temperature of the intake air is cooled back by about 12°C. It is therefore important to always recirculate the air from the room to be cooled. (In this case, the air is drawn in from the room and blown back into the room with a temperature approximately 12°C lower).
This depends on the area and volume, insulation of the building and application. A rule of thumb is 40W per m3 for insulated buildings and 60W per m3 for tents, for example.
For all heaters with an oil-fired auxiliary burner, the burner can be replaced with a gas-fired auxiliary burner.
