solartherm solar water heater

[ashok.chava]

I am looking for 200Lsolar water heater for a very hard water 600ppm minimum. I realized that solarizer only gives MS tank with coating there is a chance of corrosion due to hard water. Is solartherm good option? Do you suggest anything better?

Please let me know.

I am also looking for right option in 200Ltr solar water heater. Solarizer Ultra has a fluid exchange mechanism which they say will prevent corrosion. Can some one please throw more light?

what I have heard is solarizer only gives MS tank and there is a chance of corrosion once the glass coating goes off. Recold gives 304 SS tank. Not sure if any one using recold.p please let me know your feedback.
