Requirements and Specifications
Measures include ground source heat pump upgrades or conversions with or without a desuperheater and must meet the following requirements and specifications:
• Systems must be ENERGY STAR-Certified.
• Systems must be installed by a licensed contractor certified by the International Ground Source Heap Pump Association (IGSHPA) . Multiple technicians may be employed to meet these certification requirements, but they must have been present during the installation to qualify.
• Systems must be installed according to IGSHPA guidelines.
All system components must be newly installed. The replacement of an existing ground source heat pump thermal exchange loop does not qualify for an incentive.
Applicable home types:
• New construction single-family
• Existing construction single-family
Ground Source Heat Pump Upgrade applies to the following situations:
• Replacing an existing air-source heat pump.
• Replacing zonal electric.
• Replacing a ductless heat pump (considered a zonal system).
• Replacing a nonelectric heating system (e .g ., gas, oil, or propane) .
• Replacing the compressor portion only (compressor portion includes the compressor, a heat exchanger, expansion and reversing valves, piping connections, and control connections) of an existing ground source heat pump system is eligible for an upgrade measure when the compressor portion is ENERGY STAR.
• Installing a ground source heat pump in a new construction single-family home.
• Installing a ground source heat pump in an existing single-family home (HZ 2 & 3) without any previously existing primary heating system .
Ground Source Heat Pump Conversion applies to the following situations:
• Replacing an electric furnace,
• Replacing an electric boiler used for forced-air hydronic heating or zonal radiant heat . Only one ground source heat pump per home qualifies for BPA payment, provided all other program requirements are met . Ground source heat pumps may be connected to hydronic heating systems in residential end-use applications if all IGSHPA specifications are met .
