I just spent some quality time huddled up with the tank that was installed along with my solar DHW system, and was a little upset to discover it only carries a 6 year warranty. Did a little Web searching, and found that they all have a 6 year warranty, but compensate for that by charging 3 or 4 times as much as a standard 12-year unit.

Does anyone have any experience/recommendation for what I should consider when this one starts to fail? It's an attractive idea to try to combine the solar in/out connections with an anode rod and stick the combination into the anode rod hole in a standard WH, or use a 2nd WH somehow along with the one supplying the house.

Maybe I should just wait and see what's out there in 6 years...
