I had a question asked from a friend that I simply don't know the answer to, so I thought I would pose it to you hot water folks. In a new construction environment - money is no object - what is the best water storage that could be implemented or included in the house? Would you pour a concrete storage cistern? Drop in a couple of big tanks for stratification?? What? What would be the "perfect" config to be used with a gassifier? I really am looking to throw some ideas at my friend. The question was based off of a 2000sqft ranch.
