Hi, i'm new to diy.
Here is something I would like to do to save on my gas bill.
The bill is actually not that bad, about 32 in the month of August.
What I would like to do is add a second electric hot water heater so that when I use hot water, my 1st heater (gas), will fill up with warm or hot water from the 2nd inline heater. An electric 30 gallon 220 heater. What I would like to do is Have the 220 heater powered off of approximately 5 12v batteries that are tied to the heater thru an invertor. The batterys would be charged by a 45 watt solar panel. Would it be better to use a 110 v heater? And can I change the heater to 110?
thanks, Pete

No matter which voltage you choose, you have to be concerned about watts.
A small 30 gallon electric unit is probably 3500 watts minimum. Do you have 3500 watts available from the inverter?
You can get up to a 20 gallon unit running off 120 volts. It will probably be 1500 or 2000 watts.

Thanks for the information on the 20 gallon hot water heater.
If I was to do this, I think that is the way to go.
