A wind operated heating device is operated by a rotor. The heater has a liquid reservoir and a rotary element which is immersed in the liquid in the reservoir. The rotary element is driven by the rotor so as to heat the liquid. The rotor is connected to the rotary element by a shaft. A shield is arranged to rotate with the rotary element and is movable relative thereto such that the position of the shield member relative to the rotary element varies in dependence on the rotation speed of the rotary element so that the shield member provides a greater resistance to rotation at higher than at lower speeds of rotation.

[ What is claimed is:] [1.] A wind operated heating device comprising:rotatable driving means;a heater comprising a liquid reservoir and rotary means at least partially immersed, in use, in liquid within the reservoir and arranged to be driven in rotation so as to thereby heat the liquid;means connecting the rotary means to the rotatable driving means to be driven thereby; anda shield member arranged to rotate with said rotary means and movable relative thereto where the position of said shield member relative to the rotary means varies with the rotation speed of the rotary means, the position of the shield member relative to the rotary means at higher speeds of rotation results in greater resistance to rotation of said rotary means than at lower speeds of rotation.
