As the water heater industry accelerates its transition toward carbon neutrality and safety, low-voltage water heater pumps are redefining industry standards with their disruptive technological advantages. With years of expertise in this field, Shenpeng Technology has developed water heater pumps that excel in low-voltage environments, delivering innovative solutions that combine efficiency breakthroughs with system optimization for water heater manufacturers.

1. Magnetic Circuit Innovation: Efficiency Breakthrough in Low-Voltage Environments

Traditional pumps often suffer from significant efficiency drops under low voltage, but Shenpeng Technology overcomes this challenge through innovative magnetic circuit design. By precisely adjusting the magnetic field coupling angle between stator and rotor, we increase magnetic field utilization by 23% compared to conventional structures. This design enables over 90% energy conversion efficiency even at low voltages, eliminating the need for high-cost, high-energy permanent magnet materials.

Our proprietary "sinusoidal commutation algorithm" addresses the torque fluctuation issues common in low-voltage motors. By dynamically adjusting current waveforms based on real-time rotor position monitoring, we reduce commutation loss to just one-third of traditional solutions. This ensures stable energy output during constant-temperature operation, fundamentally preventing efficiency degradation caused by voltage fluctuations.

2. Brushless Design: Reinventing the Energy Balance Equation

The brushless architecture of Shenpeng's water heater pumps creates a distinct energy-saving advantage over traditional brushed models. Removing mechanical commutators eliminates friction-related losses while enabling millisecond-level electronic commutation, reducing energy consumption by 40% during start-stop cycles.

At the system level, the benefits are even more pronounced. Traditional 220V AC pumps require complex voltage conversion devices that waste 15%-20% of energy; our low-voltage direct-drive solution connects directly to the water heater's main control board, eliminating intermediate conversion links and boosting overall system energy efficiency to over 92%. In standby mode, power consumption stays below 3W—perfectly meeting the strict energy-saving requirements of new international standards.

3. Low-Voltage Ecosystem: Unlocking New Design Possibilities

The low-voltage characteristics of Shenpeng's water heater pumps drive a chain of optimizations for internal circuit design. From a safety perspective, operating voltages below 36V reduce insulation requirements by two grades, allowing lightweight flame-retardant wires to replace heavy-duty high-voltage cables. This reduces wiring weight by 30% and lower wiring costs by 25%.

Circuit integration also sees significant improvements. The pump's built-in MCU directly receives signals from the main control board, eliminating multiple components and reducing control board size by 25%. This modular design not only shortens assembly time but also cuts system failure rates to below 0.3‰ by minimizing interface points.

For manufacturers seeking product differentiation, our solution offers unmatched flexibility. The wide voltage adaptation (12V-36V) works seamlessly with different heating modules, while programmable flow curves accommodate both instant water heaters' high-flow demands and storage heaters' precise circulation control—providing a versatile technical foundation for product innovation.

In an era where energy efficiency defines competitiveness, Shenpeng Technology is resetting performance benchmarks for water heater pumps through low-voltage DC technology. This end-to-end innovation—from energy conversion to system integration—delivers tangible energy savings while creating a safer, more efficient, and scalable technical ecosystem. It provides water heater manufacturers with a leapfrog solution for next-generation product upgrades.
