That looks very nice!

Keep in mind that foil insulation works differently than regular insulation. I can't tell if you had some insulation on the old stuff, or if you are talking about removing batts of insulation?

This topic comes us often in certain heating and cooling discussions on other boards as people try to improve their sticks-n-bricks.

It all depends on what you're trying to accomplish ;)

Thanks! Yeah, I realize the foil insulation functions differently than regular insulation, and that, by itself, it does not add much, if any R-value. My intent with using it for this install is that it will hold in what heat is piped into the enclosure from the furnace as well as the heat lost through the floor to theoretically keep the fresh water tank from freezing.

I figure the foil stuff has to be better than the soaking wet fiberglass batt insulation previously in there that was squished flat between the bottom of the tank and the Coroplast, and the insulating properties of the foil won't be compromised by the inevitable water that finds its way into the underbelly.
