Constant heat and moisture control recovered, not vented.

Barns ventilate around the clock to manage moisture and ammonia.

Geothermal is the natural lever- it captures the heat that ventilation

would otherwise throw away.

The challenge

Ventilate for air quality, pay for it in heat

Barns hold steady setpoints — 82°F in the nursery down to 65°F at finishing — a predictable winter load. But keeping moisture and ammonia in check means constant ventilation, and constant ventilation plus heat-and-vent throws away the heat you just bought. Today 82% of hog growers with building heat solve it with propane.

The GSHP difference

Capture what ventilation wastes — and control moisture & ammonia

You have to ventilate to keep moisture and ammonia down and animals healthy. A ground-source heat pump recovers the heat leaving with the exhaust and pairs ventilation with active dehumidification — so you hold air quality without dumping energy. Drier air also means less of the damp that drives ammonia.

The heat pump recovers the exhaust heat and returns it as warm fresh air — trials measured lower ammonia and CO₂ than conventional heating.
