A tankless electric water heater that provides hot water on demand for showers and single-point use. It is wall-mounted, compact (28 x 8.5 x 22 cm), uses a stainless steel heating element, has touch controls and an LED temperature display, and is designed for residential, commercial, and hotel use.
The unit operates on 220–240 V at 50/60 Hz. Power ratings vary between 1 kW and 5.5 kW depending on the model. It should be installed on a properly sized dedicated circuit by a qualified electrician in accordance with local electrical codes.
The heater is designed for flow rates between 2 L/min and 6 L/min. Lower flow rates allow a greater temperature rise; higher flow rates reduce the temperature increase. To reach higher temperatures you may need to reduce flow or select a higher-power model.
Temperature is adjustable from 30°C to 55°C via the touch control panel. The current set temperature is shown on the LED digital display.
Working pressure range is 0.02 MPa to 0.6 MPa (approximately 0.2 to 6 bar). The unit may not activate or perform properly if inlet pressure is below the minimum; pressures above the maximum can damage the unit.
The heater is wall-mounted and uses standard G1/2 water connections. Installation requires secure mounting, correct plumbing connections, and electrical hardwiring to a dedicated circuit. Have a licensed plumber and electrician perform the installation and follow the product manual.
No — this tankless unit is intended for single-point or limited use. Simultaneous use of multiple outlets will likely exceed the flow and power capability and reduce output temperature. For whole-house use, multiple units or a larger commercial system are recommended.
IPX4 means the unit is protected against water splashes from any direction (splash-resistant). It is suitable for bathroom environments but must not be submerged and electrical connections must remain dry and installed to code.
Regular maintenance includes flushing or descaling the heat exchanger periodically (interval depends on local water hardness), checking and cleaning any inlet strainers or filters, and inspecting connections. If you have hard water, more frequent descaling or a pre-filter/softener is recommended.
Stainless steel heating elements offer good corrosion resistance and durability compared with some other materials, but they can still accumulate scale in hard-water areas. Proper maintenance prolongs element life.
Many tankless heaters include temperature controls and thermal cut-off protection. You should also have a residual-current device (RCD/GFCI) and appropriately rated circuit protection installed. Check the product manual for the model's specific safety features.
Basic troubleshooting: confirm power is on and the circuit breaker hasn’t tripped, verify water supply and that inlet valves are open, ensure flow rate meets minimum activation, check the temperature setting on the LED display, and consult the error codes in the manual. If the problem persists, contact the seller or a qualified service technician.
It can be used with hard water, but scale buildup will shorten element life and reduce efficiency. Using a sediment filter, inline scale reducer, or whole-house softener and performing regular descaling will help maintain performance.
Warranty terms and availability of spare parts vary by seller and region. The product spec does not list a warranty—check with the retailer or manufacturer for warranty length, terms, and how to obtain replacement parts.
Tankless electric units with stainless steel elements are generally quiet in operation; you may hear minor flow and heating sounds, but they typically do not produce significant noise. If you notice unusual loud sounds, have the unit inspected.
