So, it looks like you finally read my reply to your first mirror post last month.?.

Do I win a prize? Are you going to send me a dozen of those mirrors??
The north side of my house needs some extra heat! It's too far from the heat pump source in the living room..
I wonder if about 90 sq feet of mirrors would cover the surface of this 10.5 foot dish?
OR, Maybe some very thin (flexible) mirrors could be bend into the shape of the dish? (To cover all the surface area).
I could install a little black boiler at the focal point and pipe some hot water into my home..
I think this sun-tracker circuit
Solar Tracker Circuit Kit and a 12V battery and PV charger panel would add a little to the BOM, but it would be a fun project.
For elevation, I could just go out to the dish once a day and tweak the height bolt with a wrench..
When I was away on summer vacation, I wouldn't care about hot water production..
Merry New Year!
