Solar powered Preheater for Tankless Water Heater

Step 4Mirror manipulation

Mirror manipulation
-

The narrow mirror is still held up by a block, but I reassigned a Lazy Susan to hold the bigger mirror up.

The crate is held to the Lazy Susan with a regular door hinge. The mirror is held up by a piece of 1/2" cpvc that pivots on a single drywall screw. There is a cpvc straight adapter with a washer inside so the long bolt will pivot inside when it is turned. The bolt is threaded through a large nut welded onto a steel plate which is held by the wooden blocks. Thus turning the bolt adjusts the vertical tilt of the mirror and the Lazy Susan handles the horizontal pan.

This, of course, will be improved upon, using stepper motors and control electronics, but right now I just want to see the thing move hot water to my holding tank!
