Drying heat without the propane bill.
More than 80% of grain dryers run on propane. Geothermal displaces that concentrated seasonal heat - and fills the rest of the year heating your barns and shop.
The challenge
A propane spike right at harvest
More than 80% of grain dryers run on propane — roughly 850 million gallons of ag-propane a year — and the bill lands exactly when the crop is coming off and prices are anyone's guess. See what that looked like in 2013, when a wet harvest emptied the Midwest and repriced propane through February.
The GSHP difference
One borefield, working all year
Low-temperature in-bin drying and dryer pre-heat displace a real slice of that propane, with proven equipment. Because drying is seasonal, we pair it with barn and shop heating on the same property — so the borefield earns its keep year-round instead of sitting idle after harvest.
Grain drying plus barn heating — a full year of use
Winter barn load plus the harvest drying spike keep one borefield productive across the whole year.
