Application of Air-to-Water Heat Pumps for Hydronic Heating & Cooling
About this course
Modern air-to-water heat pumps are an emerging renewable energy heat source. They can also provide cooling. When combined with a hydronic distribution system, these heat pumps provide unsurpassed year-round comfort. They can also serve ancillary loads such as domestic water heating and pool heating. The efficiency of modern “low ambient” air-to-water can approach that of geothermal heat pumps on a seasonal basis, and usually at an installed cost that’s less than half that associated with geothermal heat pumps. This course introduces the technology used in modern air-to-water heat pumps and shows how to build complete systems around them.
This course satisfies the contractor training requirement set by the NYS Clean Heat program. You can submit this certificate of completion with your application to access the money for your customers. More details on page 53 of the program manual.

Working With Air-to-Water Heat Pumps
This week presents the “nut & bolt” details of working with modern air-to-water heat pumps. It examines the thermal performance of modern vapor/compression air-to-water heat pumps, freeze protection options, use of buffer tanks, modulating versus fixed speed heat pumps, and integration of an auxiliary boiler. They details will all be applied in the example systems described later in the course.
