Product description


DC Inverter Heat Pump

Air to Water Split DC Inverter Heat Pump (heating/cooling/DHW modes)
Weswen DC inverter heat pump is one of the best heat pumps for house heating so far, with advanced DC inverter technology, saving 40% electricity than normal on/off heat pump in practical operation. The whole system is optimized with variable fan speed, while the temperature compensation function contributes to a more comfortable indoor environment. It can work with solar, boiler or electric heater according to practical condition of the heating system.

Features:

  • with Advanced DC inverter technology, it saves 40% energy than normal heat pump in practical operation.
  • 5 modes to manage heating, cooling and DHW, fit your need all year round.
  • With intelligent Heating curves (temperature compensation function), the water setting temperature adjusts automatically as the house’s heat loss changes.
  • Automatically variable fan speed in 3 grades to optimize heating efficiency.
  • Can work with room thermostat / master controller / solar controller.
  • Can work with auxiliary heater.
  • Split design with water system indoor, preventing water frozen problem.
  • Aviation plug for wire connection between indoor unit and outdoor unit, simplifies installation and avoids mistakes.
  • In indoor unit contains brazed plate heat exchanger, WILO circulation pump, expansion vessel, flow switch, water pressure gauge, air vent.
  • Allows absence of buffer tank for heating/cooling.
