Frequently Asked Questions

Frequently Asked Questions

How much can I save on heating?

Nakoair solar air heaters use free solar energy to pre-heat incoming air, reducing your heating system's workload. On sunny winter days the temperature boost is 5–30°C with no electricity needed for the heat itself.

Is installation difficult?

No. Most models mount on a south-facing wall and plug into a standard socket. No fuel lines, no complex ductwork. Detailed guides and videos are available on our installation page.

Do they work on cloudy days?

Yes. The glass collector still captures diffuse daylight, and the integrated fan (low wattage) supports air movement. On very dark days output is lower, which is why Nakoair complements — not replaces — your main heating.

What about warranty?

All Nakoair units come with a 10-year warranty on the collector and are built to EN12975 / TÜV standards.

Do you ship across the EU?

Yes — free door-to-door shipping to all EU countries, VAT included. See our Shipping & Delivery policy.

Is it noisy?

No. The fan operates quietly and is suitable for living spaces, bedrooms, and offices.

What if I change my mind?

You have 14 days to return unused items in original packaging. See our Returns & Refunds policy.
