Contractors can choose from a selection of models in various capacities to suit their customers’ requirements with single-zone cooling, single-zone heat pumps for cooling and heating, and multi-zone heat pumps.

Coffee with Caleffi complimentary technical training webinar will cover air source and water source heat pump systems.

The contest seeks entries of energy-efficient project installations using Bosch Thermotechnology heating and cooling products and recognizes best entries with gift cards and recognition prizes.

The units provide energy-efficient heating and cooling as part of either a boiler/cooling tower or geothermal heating and cooling systems.

Bosch Thermotechnology Corp. offers the new Greensource Complete Design with Innovation series SM model heat pump that incorporates green technology for residential applications.

Most residential geothermal heat pump systems use closed-earth heat exchangers constructed of high-density polyethylene tubing. The overall earth heat exchanger usually consists of several parallel piping circuits joined into a set of headers.
