Hi Paul. Love your stuff, which is why I'm submitting .
Heat storage is a subject dear to my heart. I burn wood in a stove in my basement to heat my home and water. I like to sleep with no fire going to be safe. My heating the basement walls gives heat back all night and the mornings are quite nice, considering.
John Hait has a book on passive annual heat storage, and my ideas are from his works. He uses air and gravity flow ideas.i use fluid and pumps.
On the peak of a vented home roof, the summer heat causes a huge amounts of hot air to be ejected. I think a collector made from finned copper tubing, allowing the heated fluid to be pumped down into a storage bed of insulated earth would store heat to be used in the heat pump system later. Or for a retrofit to a building, into tubing cast into the inside basement wall/floor area. I think of heating, as a Maine boy with years of wood pile time in.
On new construction, the leach field is made with lots of sand, maybe use this as part of the storage mass, saving the cost of constructing the storage area.
He also recomends using beadboard insulation covered with plastic sheeting to keep it dry and allow movement. Anyway, maybe you can run with his stuff sometime.
ideas- building the roof with design citreia to enhance collection.
- fluid not air because of vermin damage
- consideration of the off time at night and winter time to stop heat losses in the home collector.
