The Westinghouse EarthDirEX™ 19+ EER, 3.9+ COP geothermal direct geoexchange heat pump is said to require less drilling than other geothermal systems. Also, there is no earth-to-water heat exchanger component, so the heat pump transfers heat more efficiently.
Groups Collaborating to Amend Illinois Technical Reference Manual
September 22, 2014
The group’s amendment would allow GHPs to be compared to 80 percent efficient natural gas furnaces; include the desuperheater water heating efficiencies of GHPs; recognize the true cost of air-source heat pumps; raise the average by 54 percent; and extend the useful life of a GHP from 18 to 25 years.
Nearly 300 WaterFurnace dealers and employees from across the country mixed business with pleasure at the company’s annual meeting in Fort Wayne, Indiana. The three-day event included a minor league baseball game and featured a mix of informative presentations, factory tours, and educational breakout sessions.
While there are still barriers to the growth of geothermal, including high first cost and logistical challenges, experts believe these can be overcome through advancing technology and educational efforts.
