COLD WEATHER ISSUES

I assume your rodi must be in the house, as no way it could work in -30.

I thought of that.. but I fear the time when I need to do a sudden water change. My RODI takes forever to produce too..

2) Build an insulated "mini-shed" around the storage containers and combine it with the pump and you will need a lot less energy. Again, need to do some calculations to make sure.

3) The "mini-shed" plus a heater on a timer, just enough to keep from freezing.

All of this and you are still going to have to do a lot to heat the water up for any significant water change or top off.

Thanks Charles. Agree with all your points. Have considered building an insulated closet in the garage.
