If the water extraction interrupted, eg by closing the hot water tap, the energy supply can be switched off immediately. Also serves the differential pressure switch or flow sensor. This is not done or delayed, can the fed amounts of energy can not be dissipated with the flowing water, the water heater to overheat. In such an incident
Eccotemp L5, the unit will be by a safety shut down and have a qualified person returned to service.
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, electronically controlled heater real subject 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, since even small amounts of water are heated only as far as necessary. The warming is largely variable.
