What about a small solar water heating system on the top of the elevated tank...something very simple, just enough to keep the water from freezing?Comment

You get good sun there at least - a solar water heating panel (or two) on the structure might do the trick.[SIGPIC][/SIGPIC]Comment

The solar collector would be BELOW the elevated tank, so the warm water can RISE (via thermosiphon) to the tank. use Poly tubing, that does not crack if frozen.
In my area, even at 25F, it takes a long time for 1500 gallons & 2" & 3" insulated pipe to freeze. Then spring comes.
I've had unprotected pipes crack, but no ice in the tanks yet.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

NW Washington has pretty cold spells - the brass monkey would be several sizes too small - but they get lots of sun.
You only need to keep the tank at maybe 35[SIGPIC][/SIGPIC]Comment
