I am readying the system with the same weight (45 lbs / 20.5 kg) of fluid as I used in all the tests except now 50/50 water/glycol.<br /><br />Several readers have suggested a test where the ambient is close to freezing and I hope to try that (with the flat plate stationary).<br /><br />I am also going to try some new small pumps that have better lift.

This is an intere...Hi George. Must be getting cold.<br />This is an interesting test idea. <br />Of course if you track the sun with either collector the temp will be higher BUT flat plates used for DHW are not normally rotated. <br />Also a better comparison would involve heating the same quantity of water over the same duration. I would keep the flat plate stationaryJC-Solarhttps://www.blogger.com/profile/13261620485870046350noreply@blogger.com
