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 ...

Heat pumps are often talked about as a single technology type, but in practice, there are two main systems used in UK homes: air source and ground source. Both systems work on the same principle, ...

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 ...

Federal incentives for home energy improvements are running out at the end of the year, so it’s decision time for anyone who has been thinking about a heat pump. The right decision can depend on where ...

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 ...

Germany’s Ait Group has introduced residential ground-source heat pumps using less than 150 grams of propane, based on results from the Fraunhofer ISE LC150 research project. The new systems deliver ...
