Know the facts about using geothermal heating and cooling system to heat your domestic hot water.
Using solar hot water to heat your domestic hot water is many times more economical than using a geothermal heating system.

Using the earth to heat your domestic hot water is inefficient and has a low COP (coefficient of performance) because of the difference in temperature from 55 degrees F to 120 degrees F.

Most geothermal heating and cooling systems use waste heat from the geothermal compressor to heat domestic hot water.
In most cases waste heat from your geothermal compressor is inadequate to meet your domestic hot water demand and resistance electric is used as a back up.

Using electric resistance heating to heat your domestic hot water is many times more expensive than using a solar hot water system.
