How the earth becomes your silent guardian and friend
Imagine a house where the air is always fresh, warm in winter and cool in summer — without noise, without mold and without huge bills.
This is not a dream.
In 2014 we transformed a steel box into a lightweight, thermally insulated EPP enclosure.
This is how GHT was born — the geothermal pre-heater/cooler that uses the earth’s stable +12 °C temperature.
In winter the earth gently warms the incoming air so the recuperator never freezes.
In summer the same earth cools the air to a pleasant 18–20 °C — without the noise of an expensive air conditioner.
The result? Stable humidity, clean air with PureFlow filters,
791 € savings per year and a healthy environment for your family for 25 years.
