Manufacturers had a lot to like about last year. According to the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), shipments of equipment increased in just about every category in 2013. Especially notable were shipments of air-source heat pumps, which were up 16 percent over 2012.
Sales of air-source heat pumps used to be concentrated primarily in the Southern U.S., but that is changing as consumers become more aware of their energy-saving capabilities. In fact, in many markets, it may be more cost-effective to use an air-source heat pump for the majority of a homeowner’s heating and cooling needs.
The energy-efficiency ratings of residential air-source heat pumps have risen dramatically over the last few years, with many manufacturers now offering equipment well exceeding the 20-SEER mark. There have been significant gains made in commercial heat pump efficiencies as well.
It’s time again for the Commercial Cooling Showcase. The NEWS’ annual issue has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.
Bob and Tim have gotten together for another informational session. Tim requested some extra after-hours training about heat pumps. In their last session, they talked about heat pump mechanical problems. This time they discuss electrical problems.
Robur captures the advantages of a condensing boiler and an electric heat pump in one unit. Robur’s air-to-water reversible heat pump supplies hot water up to 140°F or chilled water down to 41°.
Bob and Tim were taking a break and Bob began explaining some of the tips that he has learned in servicing heat pumps. Bob said, “Let’s go over some of the service problems that you may have with a heat pump.”
Carrier Corp. and Robert Bosch North America Corp., signed an agreement to form a joint venture to develop and manufacture geothermal and water-source heat pumps for the North American residential and commercial segments, the companies announced recently.
The season was getting colder and heating calls were beginning to come in. Bob and Tim were riding to a large residence that had three heat pumps to provide heating and cooling for the structure and Tim asked a question, “Why are heat pumps so popular?”
