Can Geo-Thermal Warm Your Pond In The Winter?

FORT WAYNE, Ind. (Indiana’s NewsCenter) - Last week firefighters were called to a residential pond after a family's dog had fallen through the ice and drowned. They were concerned that it was due to the owners geo-thermal heating unit. But was the concern needed?

After Indiana’s NewsCenter originally aired the story, owners of Collier's Heating and Air Conditioning contacted us to say that not only does geo-thermal “not” increase the temperature but it may actually keep your pond frozen.

Operations Manager for Collier's Heating and Air Conditioning Keri Zeplin says, “If anything, it may keep your pond colder, but with the thousands and thousands of gallons in the pond. The difference is going to be barely measurable. But it would make it colder, never warmer."

Zeplin explained geo-thermal heating draws heat from the ground bringing into your home. Because the ground stays around 52 degrees, year round, it is able to bring in cooler air in the summer.

Firefighters still suggest drilling a hole into the ice to determine how thick the ice is and recommend that it be at least 6 inches to be safe.
