Great class! A lot of information presented in an easy to follow/easy to understand format. I found the piping schematics, electrical diagrams, and sequence of operations description for the example air-to-water heat pump systems quite useful.
I absorbed a ton (ha) of great information. John Siegenthaler's material has helped guide and improve my business.
Superb!
The course provides an excellent introduction to heat pumps in general and more specifically air-to-water heat pumps. It also provides a solid base of application fundamentals and examples backed up by straight forward computational techniques that can/should be reapplied to future designs.
This course will really dissolve the mystery of how a heat pump works. It also removes the big objection of operation in cold climates.
