Yes
well worth the time.
This class does a great job of assuming the student has no knowledge of heat pumps and imparting some of the basic concepts needed to understand heat pumps.
Basic course describing the many variations in heat pump system.
This really helped be design a system for my own house. I have a electrical background and have been in and around cnstruction most of my working life. Rarely does someone take the time to stop what they are doing and explain something in such great detail. John does not "Dumb it Down" with the technical terms, but takes the time to explain what they mean and the differences of each.. It kind of reminds me when I was in trade school. Especially like the part where he explained energy and power as it relates to heat pumps. This is a really well thought out course and delivered in plain language anyone can understand. Can't wait for the next one.
