Applying Air-to-Water Heat Pumps in Hydronic Systems (Part 2)

Thursday, July 23, 2020
12 noon-1:30 p.m. CDT


Air-to-water heat pumps represent a unique opportunity to leverage the high efficiency of modern “low ambient” air-source heat pumps with the unsurpassed comfort offered by hydronic distribution systems.  All signs point to an expanding market for these heat pumps within North America.  This extended 90 minute presentation will be a follow-up to the session offered in Oct. 2019.  It will go into detail on how to apply both monobloc and split system air-to-water heat pumps for heating, cooling and DHW production.

A favorite to the webinar series, John Siegenthaler, P.E. will present design concepts that will help prepare you to offer these state-of-the-art systems.  

You'll learn: 

→ Is it really possible for a heat pump to extract heat from outside air at below 0ºF temperatures?
→ Is it possible for the coefficient of performance (COP) of an air-to-water heat pump to be as high as a water-to-water geothermal heat pump?
→ Can the outdoor unit of an air-to-water heat pump be mounted the same way as a condenser unit in a typical air conditioning system?
→ Does a heat pump with a with an inverter compressor eliminate the need for a buffer tank?
→ Should an air-to-water heat pump always get sized to match the design heating load of a building?

A seasoned industry leader and passionate teacher, John shares his over 35 years’ experience in the understanding and proper application of water-based engineering principles with our audience. He is the principal of Appropriate Designs and a regular contributor to industry publications.
