The energy efficiency revolution continues with the launch of A. O. Smith's HPI Hybrid Water Heater. HPI integrates an energy recycling heat pump module that harnesses ambient heat to generate hot water much more efficiently.

The HPI series is a light commercial model designed for indoor or outdoor installation.






Why Choose Our Product


  • Efficient Renewable Energy Technology

    This water heater is a highly efficient, energy-saving and environment-friendly device. While running in energy-saving mode, users can save up to 60% on electricity costs when compared to a conventional electric water heater.

  • AES (Adaptive Energy Saving system) function

    This water heater has a unique AES feature which adopts the heating cycles to the water utilization habit of the user. This enables the water heater to switch on automatically at the required time, saving energy by minimizing thermal losses.

  • Blue Diamond Glass Lined Tank

    This water heater comes with a special glass-lined tank. This lining offers the protection against tank corrosion and increases the life of the water heater and it is achieved through a specialized fusion process.

    The tanks are designed to pass 100,000 cycle fatigue test. This makes it one of the best tanks resistant to rust and scaling.

  • Patented Micro-channel Heat Exchanger

    The heat exchanger with micro-channels has larger surface contact and improves rate of heat transfer, maximizing the energy recovery from ambient heat.

  • Glass-lined Electric Heating Element

    Dual backup 3kW heating elements help in quick heating. If the temperature is set above 50°C, then the heating elements are activated. Users also have an option of heating the water completely in 3kW mode.

  • Extra-thick Insulation

    Tank insulation minimizes standby heat loss so generated hot water stays longer and reducing energy requirements.

  • Wired Remote Touch LED Control

    Install your water heater out of sight and control your water heater remotely through the digital touch control that fits beautifully in the modern bathroom. 

  • Real Time Hot Water Display

    Shows available hot water available in the tank.

  • Adjustable Mode Settings

    This water heater can be set by the user to operate in different energy modes: The high-efficiency mode uses only environmental heat to heat the water up to 50°C. The hybrid turbo mode uses the heating elements only if the set temperature is > 50°C.

  • Programmable Timer

    Timer feature lets you schedule times of the day when the heater automatically switches on.

  • Power-off Memory Function

    This water heater can retain the set information for 48 hours, even in power off condition.

  • High Temperature Limit Protection Switch

    This water heater employs a high-temperature limit protection switch. In case any fault occurs and the water temperature exceeds the highest preset temperature, the switch rapidly cuts off the phase and neutral line simultaneously to guarantee safety.

  • Safety Valve

    A safety valve for the water heater is provided and set while leaving the factory and it is not adjustable by the user. The safety valve must be installed at the inlet pipe of the water heater.

    This valve will relieve pressure automatically while the piping system exceeds the rated pressure. The discharge port of the safety valve and the condensate pipe should be connected to the floor drain through the three-pass discharge pipe.

  • Heat Pump Safety Features

    • Built-in Compressor Thermal overload stops compressor operation in case of overheat
    • Electronic Expansion Valve abnormal operation protection
    • High and low voltage protection
    • Refrigerant leakage protection
  • IPX4 Waterproof Outdoor Design

    Can be installed in an outdoor setting gives you more flexibility in installation location.
