Geothermal Heat Pumps

Save up to $650 on the installation of a geothermal heat pump system

Geothermal systems use the earth’s temperature to produce reliable and cost-effective energy for heating, cooling, and water heating. Even with Wisconsin’s extreme climate, temperatures remain constant a few feet below the ground’s surface. Geothermal systems exchange this constant below-ground heat with fluctuating indoor, above-ground temperatures. When combined with a large loop field or well, this results in significantly greater efficiency than traditional heating systems.

Geothermal heat pump systems are sometimes referred to as earth coupled, ground source, or water source, but they all refer to the same type of renewable energy.


  1. 1

    Check to see if your utility participates in Focus on Energy. Review program terms and conditions and check the status of available Renewable incentives. Loans are also available. 

  2. 2

    Find a Focus on Energy Trade Ally.

  3. 3

    Complete and submit the Reservation Application along with your proposal documenting a paid $500 down payment toward installation. Upon approval of the Reservation Application, an incentive will be held for three months. Systems not placed in operation within three months will lose their reservation and applicants will have to submit a new Reservation Application. 

  4. 4

     Using a Focus on Energy Trade Ally or qualified contractor, complete the installation of your system. The system must be placed in operation within three months of the date of reservation approval. 

  5. 5

    Submit an Incentive Application after your system has been placed in operation and prior to reservation expiration. Incomplete applications cannot be processed and will delay payment.
