In a convenient location on the metal water pipe that runs through the area, put the split coupling, which is a pipe of a bigger diameter welded it short pipe on the side — entrance window for the heater.
Water pipe centered inside of the coupling bolts, screwed into threaded holes of the latter. In the input window enter the neck of the heater, a blowtorch or gas burner.
Water passing through the water pipe, is heated by the flame of a blowtorch. The heating temperature is controlled by the water pressure (speed of its passage in the pipe).

Water heater:
1 — pipe; 2 — clutch-heater; 3 — centering screw; 4 — blowtorch; 5 — insulation
For the thermal insulation of the coupling is wrapped with asbestos rope or several layers of asbestos cloth. Such a coil, given the ecological harmfulness of asbestos, it is advisable to coat with clay in a mixture with liquid glass (silicate glue).
Such a device can be used for heating water and for other household needs.
