The seven-year contract for Midea calls for the development and delivery of 20,000 cold climate packaged window heat pump units – devices that support the city’s move away from natural gas and towards more efficient energy sources.

PM Engineer Columnist John Siegenthaler guest-stars on PBS’ “Ask This Old House.”

I’ve written several “Heating with Renewable Energy ”columns covering the benefits of combining modern hydronics technology with modern air-to-water heat pumps.

Did you know Walraven’s pipe reinforcement is self-gripping and provides continuous support for all plastic pipes by controlling the direction of pipe expansion, maintaining alignment of pipe and prohibits “snaking”?

As global energy planning moves away from fossil fuels and toward electricity, an increasing number of hydronic heating systems are being supplied by heat pumps. Some use water-to-water heat pumps supplied by geothermal earth loops. Others use air-to-water heat pumps.

Westinghouse recently expanded its line of mini-split heat pump systems for the U.S. and Canadian markets. 

Heated floor slabs, without floor coverings, have one of the lowest supply water temperature requirements of any radiant panel system. This makes them well-suited for use with renewable energy heat sources such as air-to-water heat pumps, water-to-water geothermal heat pumps, biomass boilers and solar thermal collectors.

The fourth edition of "Modern Hydronic Heating & Cooling, for Residential and Light Commercial Buildings" will be available through major booksellers on April 1.

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.

Napolean’s NS18 heat pump and air handler is an all-in-one heating and cooling system for year-round comfort—100% heat in the winter and 100% cool in the summer.
