solar water heater

Wondering if anyone has a suggestion or two, I'm going to be away for a month or so. The question is <<<<is there a problem with draining the system. The reason I ask is my system tends to get really hot and lets off a colum of water just like a car overheating. I'm the only person using it so I get the hot rad thing now and then, 4 times in the last month. I hate to water the street. Any thoughts please.

Contact your installer. There should have been a shutoff installed before and after the unit if only for maintenance and repair purposes.

So that you're not wasting water in a time when water supplies in the area are low, shade cloth laid across a portion of the tubes will take care of this and if your water isn't hot enough in January, remove for a month until the sun is back to its usual strength and then have it put back. Our installer charged us $100mxn to do this and it has worked perfectly.
