Geothermal Heat Pumps-Closed Loop-Pond or Lake

Summary: Geothermal heat pumps are very efficient and provide comfortable heating and cooling by using the natural heat of the earth instead of outside air to provide central heating and central air conditioning.

"Hi Carl, I am building a log home on our property (approximately 3000 sq.ft.)

I was wondering if geothermal was the way to go.

We are going to put a pond in at the same time as the new build and thought about the pond for the coils.

We also were checking to see if there are any rebates from the government for the energy saving geothermal heating system?

I can't find anything online about this question.

Thanks a lot for your time,

Mary"

Hi Mary,

If you build your pond deep enough you can use the pond water for your geothermal heat pump.

This method, the pond closed loop geothermal heat pump, is actually the least expensive closed loop system to install.

Be sure you make the at least 8 feet deep.

The water pipes that will be supplying ground temperature water to the geothermal system will be coiled into circles at least eight feet under the pond’s surface to prevent freezing.

As the principle of heat pumps relies on an ambient source of warmth, and unfrozen water is above 32 degrees Fahrenheit, your pond should be an excellent source of this warmth, providing you an efficient central heating and central cooling system.

Be sure to read my article on Geothermal Heat Pumps as well as the one on Heat Pumps.

Good luck, Carl Heldmann
