passive heat storage to be used later for a heat pump.

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.

Bert Vinyl : Welcome to Permies. com, our Sister Site Richsoil.com, and a Big Welcome to the Rocket and Wood Stoves
Forum Threads ! With over 26,000 Fellow members World wide ( The largest Permaculture Group on the Web ! ) you should be able
to come here 24 / 7 and find someone who wants to talk about -what you want to talk about !

Thanks for bringing John Hait to my / our attention, I am still working to understand how to adapt his basic designs to different sites!

Isolating the Grey Water from your Leachfield and then insulating that part of the system prior to pairing it to a Ground to Air heat pump
could be a clever way to recover much of the heat energy we traditionally waste to the Environment !

As many of our frequent posters are from the U.S. SouthWest water conservation and collection of water run-off is very important to
their goals, -doubling their gains i. e. water And energy conservation is often discussed here and in other related Forum Threads !

You may find it worthwhile to check out the good folks at Cold Climate Housing Research Center, an arm of the University of Alaska,
-Fairbanks Alaska Campus !

You and I know Cold ! They Know COLD ! Their work on the proper placement of Insolation/Insulation and Vapor barriers is an Eye
opener !

I will not be the only one to mark this thread for following ! For the Good of the Crafts -

Think like fire ! Flow like a Gas ! Don't be the Marshmallow ! As always your comments and questions are Solicited and Welcome Big AL
