PHNIX not only provide 3.5kW, 5.5kW, 7.5kW three models in demand of domestic hot water consumption for residential & light commercial application but also offer the professional hot water tanks selection according to our rich experience that have been

proved by our partners & consultants over past years.

The HeatSpring Series can maintain stable and efficient performance in a wide ambient temperature from -7°C to 45°C, providing a wider range of applications for domestic & light commercial sanitary hot water heating.

â–¶ Heat Pump With Electric Water Heater

The HeatSpring Series can provide sanitary hot water for shower and washing in domestic applications, and light commercial applications such as restaurants and salons.

In addition, it can be expanded for industrial water heating applications like milk tank cleaning and disinfection on dairy farms.

â–¶ Heat Pump With The Conventional Boiler

The HeatSpring Series can be operated for domestic hot water application in combination with various conventional boiler hot water systems like the gas boiler, coal boiler, and pellet boiler because the extended control system ensures that the heat pump unit is perfectly compatible with the existing boiler and works efficiently.

â–¶ Heat Pump With The Solar Hot Water System

The HeatSpring Series can be operated for domestic hot water application in combination with the solar hot water system because the extended control system can make sure that the heat pump unit works intelligently with the solar hot water system in all weather conditions throughout the year.

Being ahead of the average water heater on the market, the outlet water temperature of the HeatSpring Series is up to 70 °C. Its high heating performance not only greatly fulfills the daily demand for sanitary hot water, but also constantly kills Legionella bacteria in the tank, adding safeguards to the health of family members.

HeatSpring Series uses high-efficiency DC motors. When working at a high ambient temperature, the DC motor can slow down the fan speed to reduce the evaporation and avoid overload of the compressor, which considerably saves energy. Additionally, the water pumps are from the global pump leader Grundfos. It's made of composite anti-corrosive material that has higher temperature resistance and longer service life.

PHNIX's self-developed PCB can operate the heat pump unit in combination with other heat sources via Modbus RS485 meanwhile support various wired displays include LCD, LED, color touch display with significant functions like Fast Heating, Timer, PV-Ready and Remote upgradation etc.
