Electric water heaters are protected against dry burning, scalding, overheating, physical shields, splashing, leakage, water and electricity separation, magnetic induction, overpressure, water shutdown, backflow, and power outage memory functions. Quick hot water heaters mainly include pre installed dual mode electric water heaters, 3D fast thermoelectric water heaters, and intelligent capacity increasing electric water heaters.

Instant electric water heaters generally require a current of 20 or even 30 amperes or more, which is instant heating with constant water temperature, high heating efficiency, and small installation space. Internal low-pressure treatment can add a splitter during installation. Products with higher power can be installed in the bathroom, which can be used for both showering and washing. Generally, household use is energy-saving and environmentally friendly.
