I've wondered about this as well with our unpressurized drainback systems. My HVAC supplier had told me that once you heat the water above 165 or so, that you basically have distilled it. Not sure. I thought you would need to boil it. Though we have had no issues with corrosion as we have had some tanks in the field for years. Jeremy Rodriguez All Solar Sent via BlackBerry.
