Recommendations

For optimal performance, install vertically on a solid wall with access to a 230 V power supply and cold water line. Set the thermostat to 55–60 °C for a balance of comfort and energy savings. In hard-water areas, consider periodic descaling to maintain heating efficiency. Ensure the pressure relief valve is connected to a drain to prevent damage from overpressure. This water heater is ideal for users seeking a compact, efficient, and safe hot water solution for single-point applications.
