## Description

Product Description Heating On a sunny day, the temperature of the injected air is approximately 5-30ºC higher than the air inlet temperature. In addition, the air temperature on the sunny side usually rises more than 10 °C under the big sun. Ventilation Depending on the model, approx. 5 to 140 m³ dry, warm air is blown into the room per hour. The fresh air of solar air heater squeezes the turbid air out of the room, keeping the air fresh and oxygen-rich. Avoid moisture, mold, fungus, formaldehyde (HCHO), TVOC, benzene and odor. The room air can be exchanged within 2 hours. Always supplying you a clean and healthy family Improve the indoor environment, reduce the irritation caused by allergy, especially for newborns. Improvement on the dwelling atmosphere---- bring in oxygen and reduce carbon dioxide; discharge unpleasant odors which might cause allergies and discomfort; control the temperature and moisture of the room, prevent the emergence and spread of bacteria. When dry and warm air keeps flowing in the room, the damp, rot or mold would be long-term reduced. Dehumidification and Humidification: Optimum level (for comfort as well as building quality) is a relative humidity (RF) of 40-70%. Absorb room moisture and drain out the room. Ventilation + Heating = Dehumidification. Make sure the value of your holiday home and wooden furniture. Especially suitable for wooden houses and basements. Nakoair solar air heater in basement, can sufficiently solve the moisture in basement, and prolong the life span of indoor structure and electrical appliance. The problem: Humid basements. One of the first signs of humidity in the basement is the stale smell. The humidity will soon destroy items stored in the basement, such as textiles, cardboard boxes or furniture. In addition, the lack of regular ventilation will result in mould and harmful fungus. To make the rooms fit for use again they have to be heated, mechanically dehumidified and vented on a regular basis. Below 15 ºC, electric dehumidifier will frost, and dehumidification effect will be much worse. Moreover, dehumidifier needs refrigeration and consumes a lot of electricity. This usually results in high operating costs. The dry climate indoor can easily cause virus and bacteria to multiply and spread. In addition, the dry air takes away water from the body, making them feel dry, feverish, depressed, coughing, hoarse, and sore throat. Reduce the amount of air pollution and greenhouse gases that result from the use of fossil fuels for heating. Safety: low voltage, no fire, no household electricity, no smoke or dust. High solar subsidy from BAFA for OS22, OS32, OS42 in Germany. The application for the models is quite simple and can be done online. Important: The application and receipt of the corresponding confirmation of receipt must be made before the purchase.

### ⭐⭐ Livré sans thermostat

### ⭐⭐ The instruction manual is impossible to understand
*by D***. on 2 January 2025*



### ⭐ Steuerung eine Katastrophe
*by B***R on 15 March 2024*

Den einen Stern vergebe ich für das qualitativ hochwertige Panel. Zwar habe ich das Gerät schon am 30.12.2022 gekauft, konnte es aber erst im Herbst 2023 montieren. Das elektronische Steuerungsgerät ist absolut unzuverlässig und die Deckel der Belüftungsöffnungen fallen aus den Gewindestangen beim öffnen. Bei den Gewindestangen wäre eine mechanische Stopvorrichtung für die Deckel absolute Pflicht gewesen. Da die Steuerung tut was sie will, ist es immer wiedern eine nervenaufreibende Aktion die Deckel wieder auf das Gewinde zu bringen. Egal welche Einstellung man bei der Steuerung verwendet, öffnen und schließen sich die Belüftungsöffnungen nicht nach den Vorgaben/Einstellungen. Da die Steuerung über keinen Akku verfügt, ist dieses System nicht für Ferienhäuser bei denen man den Strom in Abwesenheit logischerweise abschaltet zu verwenden. In dem Moment wo die Sonne weg ist bleiben die Belüftungsöffnungen in der aktuellen Stellung und können sich nicht mehr schließen. Somit kommt automatisch kalte Luft herein und durch den Temperaturunterschied entsteht Kondenswasser, das über Nacht eine Pfütze unter den Öffnungen entstehen lässt. Bei Stromanschluss schließen sich die Deckel leider auch nicht immer und muss dies dann manuel machen, wenn man nicht frieren will. Fazit: Steuerung eine Katastrophe und Belüftungsöffnungen eine Fehlkonstruktion. Ohne permanente Überwachung/Kontrolle nicht zu verwenden. Viel Geld zum Fenster rausgeworfen.
