An experienced gardener knows that cucumbers and some other vegetables and berry plants to water should be only warm water. For those who have on the plot there is water, offer simple, proven device for heating water directly in the tube.
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).
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.
