I would like some assistance in deciding whether I should buy a solar heater
or not.
I live in Dallas TX and I am considering buying a solar heater like to
extend my swimming season. Could someone living in the Dallas area (or an
area with a similar climate) advise me of the effectiveness of using a solar
heater?
I welcome all “don’t do this” and “be sure to do that” advice!!
Thanks in advance, Randy
