Enerworks solar thermal/solar hot water system

A friend of mine here in Ottawa, Ontario, Canada was kind enough to let me photograph the Enerworks solar thermal system he installed for his home. If you're not familiar with how an Enerworks system works see the details and diagrams on the main solar hot water page here.

Videos of this Enerworks solar thermal installation

Part 1 - Tour of this Enerworks solar thermal system

As well as a tour this details the steps involved in heating the water using solar and what happens when a tap is opened to draw water from the system.

Part 2 - Details on some of the parts

This video goes into details about:

  • the controller,
  • temperature sensors,
  • expansion tanks,
  • flow meter,
  • bypass valve assembly and
  • stagnation control including the Enerworks vent, covering the panels with a tarp, using a heat dump radiator, vacation bypass valve and vacation overheat feature.
