Known auger consumes electrical energy and is not intended to heat water. The blade's surface and auger have a smooth surface that does not hinder the movement of the environment.
The closest to the technical nature of the claimed solution is the friction heat generator comprising a vertical cylindrical housing with cap and plate, drive shaft, pipes entrance of cold and hot water outlet and hydro (RF Patent No. 2380625). Known heat of complicated design and has a significant number of moving pistons in the cylinders, that is riodic to their rapid deterioration, with problematic replacement.
The task of the present technical solution is to increase the friction between the surfaces and their gradual convergence and increased roughness of the rest of the surfaces involved in the technical transformation of energy into heat.
The task is achieved by the proposed wind friction heat generator, comprising a cylindrical housing with a lid and a bottom, the drive shaft of which the top has a flange is mechanically coupled to the shaft flange of a wind turbine. At the bottom of the lid on the case on the right has the outlet nozzle of hot water to the consumer and to the left at the bottom of the inlet nozzle of the cold water from the municipal water supply system.

Wind friction heat generator includes a cylindrical housing 1 with a cover 2 and a bottom 3, the drive shaft 4 whose top has a flange 5 which is mechanically coupled to the flange 6 of the shaft 7 of the turbine (not shown). Beneath the cover 2 on the housing 1 on the right has a nozzle 8 of the hot water outlet to the consumer and to the left at the bottom of the socket 9 of the inlet cold water from a cold water supply. The shaft 4 with the lid 2 has a flange 10, is rigidly connected at the bottom with a flange 11 of the screw 12, and laterally with the plate 13 having apertures 14 for accession to this peripheral screws 15.

Wind friction generator works as follows.
When there is a wind of sufficient strength and powerful wind turbine (rotary, rotary or other) will begin to rotate together with the plate 13 screws 12 and screws 15, will begin the conversion process due to friction of mechanical energy into heat. Valve after the pipe 8 (not shown) remains closed until the temperature of the water in the body 1 of the heat to 60-70°C. Then the valve open and with the wind the consumer will get hot water from the said temperature. At the termination of the wind heat storage substance with the phase transition in the ring 23 will send the heat moving in the housing 1 water and some time to maintain its temperature in the interval sufficient for the consumer. Upon resumption of the wind process hot water supply is resumed.
In operation, the heat source disks 18, 21 and 22 will be used up, and the disk 18 by moving the key under his weight will go down and the conversion process will not be interrupted. The number of rings 23 and their volume can be increased up to the optimal value, and thus the user will be able to get hot water to an acceptable temperature.
