Solar hot water vs. tankless systems
I live in southern Louisiana. We're renovating a very old house, using spray foam insulation in the outer walls, roof and under the house.
We had a solar company come out over the weekend. With rebates from the state and Fed's, we would have to pay $2000 for an 80 gallon solar water heater. About the same price as a tankless heater.
What are the pros and cons or each?
