## Description

Nakoair OS10 Solar Air Heater - 250 kWh, up to 10 m2 | Solar Heating, Ventilation, and Dehumidification: Creating Healthy Indoor Air : desertcart.co.uk: DIY & Tools

## Features

- SUN ONLY: ventilation, dehumidification, humidification – a solar air heater, no electricity costs in sun, a healthy indoor climate. Under clear sky the Nakoair OS10 blows warmed air into the room – up to 250 kWh of heat a year at 42 m³/h, up to 10 m2. The supply air is 5–30 °C above the intake air; the exact temperature rise depends on the airflow. A PV panel drives the fan, no wall socket needed. Without sun the unit stops; weak winter sun is enough.
- DRY INSTEAD OF MUSTY: ventilating and heating in a single pass – about 2 hours for an air change, humidity held at 40–70 %. Electric dehumidifiers freeze below 15 °C and keep drawing power. A musty smell is usually the first warning sign, long before damage shows. Ventilating and dehumidifying in one unit – camper, boat, garden shed, basement, small studio, even without a socket. Dehumidification through air and heat. Keeps the air dry: less moisture, fewer bad smells.
- EFFICIENT AND BATTERY-FREE: solar appliances are eco-friendly and cut CO₂ emissions. Less airflow means higher temperature and less fan noise; more airflow means more heating power and more dehumidification. The thermostat needs no battery: once the set room temperature is reached, the fan stops. Low voltage instead of a flame, no smoke indoors. The fan knows only two states: on in sun, off without sun.
- ABOUT AN HOUR ON THE WALL: hole saw, brackets, duct and all accessories included; for timber and lightweight walls a cordless drill is enough. The collector stays outside, the outlet inside. Tempered solar glass with 92 % light transmission.
- ROBUST, QUIET, DURABLE: Built to ISO 9806; lower airflow also reduces noise. Sunon double-ball-bearing fan, 70,000 h service life and 40,000 h warranty; fitted in about an hour, a part swapped in 30 minutes. An independent laboratory confirms thermal output, breakage and stability, resistance to solar radiation, rainwater, frost and mechanical load. Maintenance-free.
