Heat pump WSDC-050-B
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.
