Infinitely electronically controlled instantaneous water heater with
21 kilowatts peak power.

L2 of the upper clamp connection (second from left) is already
scorched and melted on the corresponding vein isolation. The device is
not reliable.
For electronic instantaneous water heaters can select the water
temperature at the device. To the mixture of cold water is not
necessary. But even if a mixing valve is used, even a thermostatically
controlled, subject to true electronically controlled water heater is
no longer the limitations of the hydraulic water heater, the heater is
specifically required for proper thermostatic mixing valves.
Benefits are increased comfort and a slightly better efficiency, which
enables energy savings of up to 20% compared to hydraulic
