System COP is a more relevant metric of geothermal heat pump performance since the owner is paying for the electrical energy to operate the heat pump and the circulator, and their operation is always simultaneous.

The Inflation Reduction Act of 2022 has delivered good news in the form of federal income tax credits and accelerated depreciation deductions that help make geothermal a more attractive option.

More and more hydronic heating and cooling systems are being designed around air-to-water and water-to-water (geothermal) heat pumps. When the heating distribution system is extensively zoned, a buffer tank is typically installed between the heat pump and that distribution system.

What does a looming housing shortage, a significant increase in energy prices and 52% of home buyers ready to heat and cool their homes with electricity have in common? They’re all remedied in the same way: All-geothermal residential developments.

Each module is $140 for RPA and IAPMO members, and $170 for non-members.

According to the U.S. Energy Information Administration, more than half (51%) of the energy used in U.S. homes is directly spent on just two end uses, heating and air-conditioning. As such, producing a comfortable temperature within your living space creates one of the biggest carbon footprints of our modern living environment.

The state-of-the-art facility houses IAPMO R&T’s Oceana research center and product testing laboratory.

I recently designed a system for my daughter’s new home with a water-to-water geothermal heat pump as its main heat source. 

To compare and contrast HVAC systems according to their 30-year life-cycle cost analysis, the Xylem study analyzed seven elementary and middle schools located in South Carolina Climate Zone 3A, a humid, warm climate.
