Is ASHRAE Getting It Right With Solar Thermal System Design?
I was interested in taking a gander at the ‘official’ ASHRAE solar thermal design manual since I see so many commercial specification packages done poorly. I know many PEs refer to the ASHRAE literature when a client asks them to put solar hot water system on a building project. The engineers do the only thing they can – they go to the ASHRAE documents and copy/adapt the designs to their projects. Even ASHRAE is seeing many design errors in the field.

In the video below, I take a closer look at the ASHRAE design to see why it costs so much and has such poor performance. Some recommendations are still repeated – using glycol, for example. I’d love to hear your feedback.
