PPP has been manufacturing in Portland, Oregon since the 1960s.

Now, let’s compare the two options, a tank of water to a concrete slab, to find it would take about 5,700 gallons to store that same amount. So, compare the cost of 61 yards of concrete to an insulated tank that size. Hopefully, you have a Swiss connection if you want to shop for a tank like that.

One more thing. Perhaps you may recall the rock bed thermal storage concept? It consisted of a crawlspace full of rocks. A blower or duct system would move air across the rocks to warm the home or building. In this Legionella-aware society, that may be a hard sell. A box of hot rocks below your living space? It reminds me of my Boy Scout days when we would warm rocks by the campfire to surround our sleeping bags when winter tent camping.
