Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with annual export value exceeding US$5 million. Leveraging our decades of experience in precision manufacturing and global supply chain management, we proudly introduce our PLC Controlled Energy-Efficient Constant-Temperature Heat Pump Water Heater designed for 24/7 uninterrupted operation. This product combines advanced PLC automation with heat pump technology to deliver stable hot water while drastically reducing energy consumption. Whether for industrial processes, commercial facilities, or residential complexes, our solution ensures reliable performance and lower operating costs.

Key Features & Technical Specifications

Intelligent PLC Control System: The built-in programmable logic controller allows precise temperature regulation (±0.5°C), remote monitoring, and customizable scheduling. It automatically adjusts compressor speed and fan operation based on real-time demand, optimizing energy use.
High-Efficiency Heat Pump Technology: Utilizes R410A/R134a refrigerant (environmentally friendly) with a scroll compressor. Achieves a Coefficient of Performance (COP) of up to 4.5, meaning for every 1 kW of electricity input, you get 4.5 kW of heat output – saving up to 75% compared to conventional electric heaters.
24/7 Continuous Operation: Designed with heavy-duty components and redundant safety systems, this unit can operate around the clock without performance degradation. Ideal for applications requiring constant hot water supply, such as hotels, hospitals, and production lines.
Durable Construction: Inner tank made of SUS304 stainless steel (or optional SUS316L for corrosive environments). High-density polyurethane insulation (50mm thick) minimizes heat loss, maintaining water temperature for extended periods.
Wide Applicability: Suitable for ambient temperatures from -15°C to 45°C. Available in capacities from 100L to 2000L, with multiple electrical configurations (220V/380V, 50/60Hz) to match local grids.

Parameter	Specification
Model Range	BL-HP-100 to BL-HP-2000
Heating Capacity	3.5 kW – 45 kW
Max Water Temperature	60°C (optional 70°C)
Rated Power Input	0.8 kW – 10 kW
Noise Level	≤ 55 dB(A)
Protection Class	IPX4 (indoor/outdoor optional)
Warranty	3 years (compressor 5 years)

FAQ – Frequently Asked Questions

Can this heat pump water heater work in cold climates?
Yes, it operates effectively in ambient temperatures as low as -15°C. For extreme cold regions, we recommend an optional low-temperature version with an auxiliary electric heater.
What is the lifespan of the unit?
With proper maintenance, the expected service life is 10–15 years. The stainless steel inner tank resists corrosion, and the compressor is designed for long-term use.
Do you provide installation manuals and support?
Yes, each shipment includes a detailed installation manual in English. Remote technical support and on-site commissioning (if required) are available upon request.
Can I integrate this with my existing solar water heating system?
Absolutely. The PLC controller can be programmed to prioritize solar heating and use the heat pump as a backup, maximizing overall efficiency.
What certifications does your product have?
Our products comply with international electrical safety standards. We can provide CE, RoHS, and other certifications based on your target market – please specify your requirements during inquiry.
What is the lead time for a standard order?
Typically 15–30 working days, depending on quantity and customization. For urgent orders, please contact our sales team for expedited options.
How do I clean the water tank?
The tank is equipped with a drain valve and a clean-out port. We recommend descaling every 6–12 months depending on water hardness. Detailed instructions are in the manual.
Is the PLC control system compatible with remote monitoring?
Yes, we offer optional Wi-Fi or Modbus modules for remote monitoring and control via smartphone or PC. This feature is customizable.
