Earlier posts regarding the Kenogami House talked about using a phase change thermal battery, to avoid overheating during sunny winter days that provided too much passive solar heat. How well did that experiment work at collecting excess heat?
It was also mentioned using the radiant hydronic floor, moving purposely heated water in the radiant tubing to help balance the excess heating. My understanding was that the unheated water in the tubing would absorb excess heat from the areas of the house that received direct sun, and collected passive solar heat, and moved the water through the tubing to the areas of the house that did not receive direct sun to “balance” the heat throughout the home. How well did this technique work?
