Fan heaters are often the least expensive alternative for permanent heating of a building. They give very high output for each invested amount of money (W/money) and are easy to install. Automation is built into the units, but they can be equipped with accessories such as an automatic temperature control (for temperature reduction at night and on holidays), external thermostats, air directors, etc.
Wall mounted fan heaters can be equipped with a mixing cabinet to take in fresh air and mix it with indoor air in the desired proportions. This method solves both the heating and the ventilation issue simultaneously in a simple way. The mix of internal and external air can be automatically controlled with a damper and automatic temperature regulator. This regulator can also control the exhaust fans to provide balanced ventilation.
Fan Heaters are well suited as laundry dryers in e.g. residential drying rooms.
