Evaluating Hot Water Meter Data from The Healing Place
In this video I analyze the data we recently collected from the hot water meter we installed at The Healing Place. This is actually the first of four data sets we will need to evaluate for the entire facility in the process of our design for their solar hot water system. Information from our datalogger […]
More Hot Water Metering at The Healing Place
In this video I show how we set up a non-invasive flow meter on another hot water line at The Healing Place of Wake County as part of our design process for a solar hot water system. The flow meter requires a straight run of pipe in order to properly collect data. In addition to […]
Dr. Ben Attends ASES 2011
The American Solar Energy Society (ASES) held its 40th annual National Solar Convention at the Raleigh Convention Center last week. The turn out was impressive and I had the pleasure of seeing many old friends and making some new ones. I also had the honor of being a panel member in two of the breakout […]
Design Advantages of Drainback Solar Hot Water Systems
Watch this video illustrating the design advantages inherent to drainback solar hot water systems. This is a follow-up to my three part video series on pressurized glycol solar water heating systems. If you haven’t seen that yet, you can click here to catch up. Unlike pressurized glycol systems, the drainback design requires none of the […]
Further Design Pitfalls in Glycol Solar Hot Water Systems
I recently received a post on my blog from a subscriber in the U.K. by the name of Cleland who has installed numerous glycol solar hot water systems. He said he was starting to encounter many of the problems I’ve been describing lately. In particular, he mentioned the following headaches… Stagnation and boiling of glycol […]
