How much does a GAHT system cost?
between $2,000-5,000
Typically, residential GAHT® systems (under 1,000 sq. ft.) cost between $2,000-5,000. Larger commercial greenhouses and school greenhouses typically cost $5,000-$15,000 depending on size.
How does a GAHT system work?
A GAHT system works by circulating greenhouse air underground through a series of perforated tubes. The air flowing through the tubes is either heated or cooled by the thermal mass of the soil before it’s exhausted back into the greenhouse.
How deep does a climate battery need to be?
about 3’4”
How deep should the climate battery go? A typical 3-layer, 4”ADS tubing climate battery can be buried to about 3’4” of depth. This allows for a deep layer at 3’4” deep, a middle layer at 2’4”, and a top layer at 1′ 4”, with 12” of soil above it for root zone and garden tools.
How much thermal mass does a greenhouse need?
A wide array of design variables means the amount required is different for each greenhouse. A general rule of thumb is to use 2 to 5 gallons of water per square foot of glazing area if thermal mass is your primary climate-control strategy.
Where do you put a thermostat in a greenhouse?
A good location is at plant height near the center of the growing area. Some growers install the thermostat so that it can be raised or lowered for different crops. A thermostat mounted on an endwall or sidewall of the greenhouse (a location that heating equipment installers usually choose) will not give good results.
How many water barrels does it take to heat a greenhouse?
Divide the number of gallons by 55. That’s the size of most large barrels. The resulting number is how many barrels you’ll need to heat your greenhouse. In this case it’s a little over four, so you’ll need five 55-gallon barrels.

How can I heat my greenhouse at night without electricity?
The main ways to heat your greenhouse without electricity are: natural thermal masses such as water barrels or dark stones, as well as compost and even chickens. Depending on the size & indoor temperature needed, these methods–and good insulation–can heat a greenhouse.
