Do any of you know a good book on building a Hasa House? Have any of you ever built one? Any information would be appreciated. Thanks again for your time.

    Saw one in central Illinois.

    It's supposed to be a wood burner, you make up a piping manifold with lot's of 3/4" that goes all around the welded steel fire box about 6"+ away. Picture a cage with no top or front. Then you build an insulated shed 6"+ around the whole thing, and fill it with sand. This gives you a 12" thick heat sink to draw from. Problem was this guy thought PVC would be easier to work with and when I asked him how it was piped he himmed and hawed and showed me a picture. He never heard of the term reverse return. He thought the pump was no good, I suggested that he probably had melted plastic in the sand....he didn't like that. He would fill the firebox with pine and fir and let it rip, and what water came out was luke warm. I understand that at one time someone sold plans in the back of magazines like Popular Mechanics, etc. and that the design was based on a working units somewhere, but I can't confirm it.
    Now you know all that I do about HASA's. Art

    Hasa House

    Art,
    I'm still here! I have a friend who built a Hasa house. He had a boiler manufactured by a welder. He then built a 12x12 cement block structure, with a smaller structure inside to support the tank. The empty air space was filled with gravel. Add a heat exchanger and a pump and there you go! I'm not sure if the firebox had firebrick on sides and bottom or not. The price has to be cheaper than an outdoor wood burner. I wonder about efficiency though.
