Thanks for the input, Jeff. Man, that water temp controller sounds interesting, but way past my technical skill. My 7 p.m. to 7 a.m. proposed schedule comes more from my reading that DO levels tend to drop when the sun goes down, and reaches its lowest point just before sunrise...but now that you mention it, that time frame would keep me away from costly "peak" killowatt hours.
I still drive a pickup but I'm keeping it at 60 mph which improves my gas mileage by nearly 15% over my usual 70 mph...though it does get me some looks and a few horn honkings.
