I want to be able to keep water from freezing, to -45 degrees. I don't want to use straight anti-freeze, I don't want the smell. Can I use a high concentration of salt water(good to aprox -25) and then top it off with auto antifreeze

As soon as there is a hick up the big boys, the friends of the politicians all put their hands out for help. Who else believes the crises will last until the last cent is dragged out of Washington, Ottawa, London etc.

I'm building a solar collector. during the day the heat in the collector slowly goes up. As temp gets higher than the temp in the reservoir, I want a pump to turn on. in the evening the collector cools and the temp becomes lower than the reservoir and I want the pump to turn off.

Both temps can vary from -40 F to plus 180 F Does anyone know of a thermostat that will work in this manner

one thermostat two sensers. Temp at both sensers varies up and down all day. as long as "A"is hotter than "B" contacts closed, If "B" becomes hotter than "A " contacts open. Both sensers must be able to operate between - 40 and + 180 degrees F

Make sure the ship docks at all ports of call. Tenders from off shore can be a real hassle.

I know the 16 is the rim size. Please when you answer pretend I'm really dumb. ( EG. What do the numbers mean and why)
