    When I read Fire and Water, by Art Sussman and Richard Frazier, on this web
    site (, I decided I had to build one of these things.
    It helped that I already had a barrel stove. The whole project started with
    an attempt to cut down a very large monthly electric bill, especially in the
    winter. This approach appealed to me because it was lo-tech, simple and
    relatively inexpensive.

    I used the information contained in the article as a guide and built the
    barrel stove hot water heater described below. I am pleased to say that it
    works as advertised. So far the cost for the system, as illustrated in
    Figure 1, is less than $200.00. I expect to save at least $50.00 per month
    by operating it every 2nd or 3rd day for hot water in the summer. In the
    winter it will run continuously when I expect to save more than $200.00 per
    month for heat and hot water. Not counting my labor and research, that's a
    pretty good investment.
