Anyone have one or something similiar, ? I found two propane models on the internet, but they want $369 dollars, there good for big water tanks 500+, and require a bigger 100 gallon propane tank to use.

I need something smalller for my 100 gallon water stock tank, no electricity there, and i can use a 20lb propane bottle to, or diesel to.

I have electric, but its about 500 feet to the house, I don't think a 1500watt drain plug de-icer will work correctly with the biggest extension cord I can find...

Any help would be appreciated.
Thanks!
John
