Rheem makes a storage-tank style water heater for home use which is
polybutylene-lined with no magnesium anode, and all plastic wetted
parts. (except the heaters which could probably be upgraded to teflon)
This would be cheap option, however it means storage of the heated D.I.
which I presume is bad.  Does anyone have experience with storage of
D.I. in a tank?
