KFXRS-40 II P/C Energy-Saving Commercial Hot Water Pump

 
Highly Efficient and Energy-Saving to Reduce Cost

TENESUN commercial hot water air source heat pumps utilize advanced air source heat pump technology by absorbing free heat from the air to heat water. Its function is beyond the traditional electric and gas hot water heaters. This means that TENESUN air source heat pumps only need the 1/4 electricity of electric hot water heaters and 1/3 to 1/2 power of gas hot water heaters under the same heat status. It will save you a lot of energy fees and reduce operating costs significantly with the long-term use.

Scenario-Based Solutions


Small-to-Mid-Size Hotels & Homestays (50–200 Rooms)

Mid-size hospitality venues need efficient hot water solutions that don’t compromise guest experience. The KFXRS-40 II P/C Energy-Saving Commercial Hot Water Pump delivers 860L/h (20℃) and 589L/h (7℃) hot water capacity, ensuring steady supply for guests while reducing energy bills significantly. Its low noise range (52–63dB(A)) maintains a peaceful atmosphere, and the IPX4 waterproof rating makes it suitable for outdoor installation—saving indoor space for other facilities.


Community Hospitals & School Dormitories

Community hospitals and small-to-mid-size school dormitories require safe, centralized hot water for staff, patients, and students. The unit’s zero-safety-risk design (water-electricity separation, over-current/overload protection, water temperature protection) ensures safe usage for vulnerable groups. Its wide operating temperature range (-15~45℃) and stable COP (3.91 at 7℃) guarantee reliable performance in cold climates, eliminating concerns about hot water shortages during winter.


Gyms, Swimming Pools & Small Factories

Gyms and swimming pools have high-frequency hot water needs for post-workout showers, while small factory dormitories require cost-effective employee welfare solutions. The KFXRS-40 II P/C Energy-Saving Commercial Hot Water Pump meets high-cycle usage demands with its continuous output, and its energy-saving technology cuts utility costs by 50%. The R410A refrigerant ensures environmental friendliness, aligning with green business certifications, and the easy-maintenance design minimizes downtime—critical for businesses operating long hours.


Core Product Features


Exceptional Energy Efficiency

Captures free atmospheric heat for water heating, reducing energy consumption drastically compared to traditional systems.
