The variable speed pump uses much less power than constant speed older ones. Power Costs about $69 per month. The solar keeps it above 80 8 months of the year (I live inland). So no gas/heat costs other than the pump runs higher rpm 3-4 hours per day.
It doesn’t seem to lose much water, so I’m not sure water rationing is a major issue, other than filling it the first time. You do need to change the water once in a while. Not sure, but I heard 5 years? At some point it seems the water chemical balance can’t be corrected as easily.
