The solar system is finished, but on one of the first days, something went wrong. In spite of the various sensors and pumps, the circulator pump stopped working. Temperatures at the top of the collector reached nearly 350 degrees! Ken put tarps up to shade the panels until the plumber could come and fix it. It’s mostly working now.
We still have some sort of air bubble or something. If it gets too hot too fast, or if we’re not using the heat, something triggers the emergency shut-off settings. The pumps never have a chance to turn on and circulate to the heat dump outside. We’re still working out the kinks.
