Vallox AITO Home heat air heating device

Vallox Aito Kotilämpö is an energy-efficient air heating machine that can be connected to all heating systems, including low-temperature geothermal systems. It can be installed in place of Valmet Kotilämmo without major changes to the ductwork. It can also replace e.g. Aeromaster, Energiset, Himablock, ILA-15, Oilon Oiva, Parma 10 and Thermovent air heating machines, although you should be prepared for small ductwork changes.


The Vallox Aito Kotilämpö air heating machine has DC fans that consume half as much electricity and significantly better heat recovery in terms of efficiency. The ventilation part has a cross counterflow cell and the annual efficiency of the machine's heat recovery is 77%. Compared to old air heating machines, energy consumption is significantly reduced.


The ventilation part has automatic heat recovery with partial bypass, a maintenance reminder, a weekly clock, and built-in humidity and carbon dioxide sensors that increase ventilation as needed. The MC automatic defrost keeps the efficiency high even in severe frosts and does not increase the negative pressure in the building. A carbon dioxide sensor or an additional switch can also be connected to Vallox Aito Kotilämpä, for example for boosting or fireplace function. The filters in the ventilation part clean the incoming air effectively. The ventilation is controlled with the MyVallox controller or via the home network, home automation or cloud service.


The air heating part has a 6-row liquid circulation heating radiator, which allows you to heat the apartment efficiently and still draft-free with a small circulating air flow. The power of the heating coil is controlled from the same controller as the ventilation. The circulation fan has its own four-stage controller for speed control.
