Frequently Asked Questions

Is my current installation suitable?

In most homes, yes, especially with underfloor heating or low-temperature radiators. If in doubt, we'll schedule a heat loss calculation and check the water-side balancing/buffer tank.

Can the Windmi also supply tap water?

Yes, in combination with a suitable hot water tank. We recommend the correct boiler capacity and install the hot water hydraulics correctly.

What about sound?

The Windmi is whisper-quiet under partial load and meets current noise standards. Proper setup and free airflow remain important.

What is the delivery time?

Standard delivery time is 2–7 business days after ordering (depending on the delivery address and carrier). We'll schedule an installation date together.
