With a little guidance on ground-source heat pump design temperatures and a few rules of thumb for ground loop flow rates, most engineers are pretty comfortable designing the building side of a ground ...

When ASHRAE’s original book on ground source heat pumps was published 17 years ago, such systems were used mainly in residential settings and, according to the association, the designers who used them ...

Researchers in Sweden sought to raise the efficiency of ground source heat pumps by combining their operation with that of PVT systems and free cooling. Through a series of simulations, they found ...

Dimplex has launched the Latitude Commercial heat pump, which at just 52 dB(A) at measuring point A7/W55 is the quietest ...

Geothermal, or ground source, heat pumps are highly efficient for heating and cooling homes across a wide temperature range, ...

Federal incentives for heat pump installations expire this year. Homeowners can choose between air-source and ground-source systems. Heat pumps cut energy use and emissions more efficiently than ...

The future is bright for a little known yet highly efficient method of heating and cooling, a new report by the U.S. Department of Energy concludes. Ground source heat pumps could heat and cool the ...

Ground source heat pumps, a small but growing segment of the U.S. heating and cooling sector, could help slash energy demands, boost American manufacturing and stabilize the electric grid as AI-fueled ...

Heat pumps can reduce carbon emissions associated with heating buildings, and many states have set aggressive targets to increase their use in the coming decades. But while heat pumps are often ...
