This is certainly unreliable, and does not introduce a consistent, evenly distributed chlorine residual of 50 to two hundred ppm all over the procedure.
Thermal disinfection or pasteurisation is usually executed by elevating the temperatures in the calorifier or water heater to 70°C for at least 1 hour. This hot water should really then be drawn to every outlet or appliance making sure the temperature does no slide under 60°C.
