I am thinking of building my own solar heater using copper tubing as we do not have the type of DIY solar heater kits that is available on your market. Can anybody advice on the following?
1) what are the consequences of 4000 - 4500 ppm salt against the copper tubing?
2) anybody knows of any links to any website on the design and construction of such heater?
I intend to install the panel and tank on top of the roof and have my pump do the circulation between heater tank and pool water. Any suggestions willbe most appreciated.
