    This was actually nor a windmill nor a turbine. It's function was to heat water by use of a "water brake" which is basically a turbine, which instead of moving water, heats the water by friction.

    The heat generated by the water brake was transferred to a 2000 litre vat in our barn trough a closed-cirquit pipe system about 80 metres long. In this vat was a heat exchanger which fed to our floor heating and which we could use as tap water (via a switch between geiser and mill water).

    This switch was later changed to have feed water from a far more effective Solar Panel. At current, the solar panels preheats the water for the high-efficiency (natural gas)-boiler, which feeds it into our floor, radiators and tap water. In summer, the tap water will often reach dangerous temperatures of 80 degrees C and more (once even 96 C). In winter the solar panels still preheat the water to 30-40 degrees C, the boiler then afterheats it to 60 C.

    Also interesting is the automatic head rotation by a servo rotor: a small rotor which directly rotates the head of the windmill (with a 1:120 reduction). When the mill was "on" the servo would be on a 90 degree angle with the main axis so the rotor would stop when it no longer caught wind, then the main blades would be in full wind. When "Off" the servo was angled so it was in line with the main rotor.

    My father used to be very into durable building, this was one of his less successful projects.

    He bought the windmill from a guy called Huisjes in Hellendoorn.

    Due to ongoing mechanical problems my father had to go up there about every weekend to make adjustments and/or repairs.

    The decision to decomission the windmill was made when after one summer storm, the insurance (and especially liability insurance) on windmills tenfolded.

    Also, he had installed solar panels (for warm water) which proved far more effective and far less troublesome (only one breakdown in 15 years, and that was electronics) than the windmill.

    Decommisionning also made it possible to reshape our garden.

     Future Plans
    The windmill is for sale. In our barn is one set of wooden rotors. So if you are interested, I can bring you into contact with my father for further technical data and/or a bid.
