Has anyone figured out what is cheaper, leaving your hot water heater on electric on all the time or turning it on and off as needed. The world wonders.

In my experience, straight propane recovery is much faster than straight AC recovery, so if you need quantities of hot water, propane is better. Best is to use both at the same time, if AC is available.

That is by design
Propane burner supplies 8800 to 10,000/btu hr.
Electric is only 4777/btu hr. (1400W)
Electric recovery 6/gal hr.
Propane recovery 11.5-13.5/gal hr.
Combo recovery 18-20/gal hr.
