Basic course describing the many variations in heat pump system.

by Frank Smith, Gate House Watch 05/18/2023

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.

Mr. Siegenthaler is like a really great coach - always reinforcing and emphasizing mastery of the basic knowledge and skills that are necessary to achieve top performance. And like a really great teacher, he never confuses, never over-complicates. If you didn't quite get what he just said, don't just brush it off. Listen to it again. Or read it again. Don't give up. Listen and read carefully. Sometimes you have to work hard to be able to understand something. When you really understand something, that becomes a powerful tool in your hands.
