FAQ
- What type of refrigerant does this heat pump use, and is it environmentally friendly?
- It uses R290 (propane), a natural refrigerant with an ultra-low Global Warming Potential (GWP = 3). It fully complies with global F-gas phase-down regulations and is an eco-friendly alternative to HFC refrigerants.
- What is the minimum ambient temperature for reliable heating operation?
- The heat pump is engineered to operate reliably in cold climates down to -25C, providing consistent heating without excessive defrost cycles.
- What is the maximum outlet water temperature for heating, and the minimum for cooling?
- Heating outlet water temperature can reach up to 75C, while cooling outlet water temperature can go as low as 5C. This wide range suits various applications including radiators, underfloor heating, fan coil units, and chilled water cooling.
- What is the energy efficiency rating of this heat pump?
- It achieves the European ERP A+++ energy efficiency rating, the highest class under EU regulations, significantly reducing electricity consumption and operating costs.
- Does it come with smart control features?
- Yes. Wi-Fi and APP control are included as standard configuration, allowing remote monitoring, scheduling, and temperature adjustment via smartphone. An optional built-in 4G module (with SIM card and three years of free data) is also available, supporting an IOT platform that can monitor an unlimited number of heat pumps in a single system.
- Can this heat pump be connected to solar panels?
- Yes. An optional built-in MPPT module allows direct connection to solar panels for PV power generation without requiring additional inverters or batteries, significantly reducing system cost and complexity.
- Does it support both solar and grid power?
- Yes. The dual power supply design allows operation using solar PV power, grid power, or both simultaneously. The system automatically adjusts the power supply ratio based on real-time PV intensity.
- Can this unit provide both heating and cooling as well as domestic hot water?
- Yes. It is designed for versatile applications - providing space heating, cooling, and domestic hot water for both residential and commercial use, with intelligent auto mode switching.
- Are the hydronic components built into the unit or external?
- You can choose an optional integrated package including a variable frequency water pump, expansion tank, auxiliary electric heater, and three-way valve (for heating/DHW switching). This eliminates the need for an external hydraulic module, saving installation space and simplifying the installation process.
- How does the water pump control work?
- The built-in inverter water pump automatically adjusts its speed and flow rate based on the preset temperature difference (Delta T), optimizing energy consumption while maintaining stable system operation.
- What are the key premium components used in this heat pump?
- It uses high-quality components including a Panasonic or Mitsubishi inverter compressor, SWEP brazed plate heat exchanger (condenser), high-efficiency hydrophilic ceramic fin evaporator, DC fan motor with silent fan blades, R290 refrigerant leak sensor, PWM intelligent compressor drive module, Electronic Expansion Valve (EEV), pressure/flow/temperature sensors, and a 4.3-inch touch screen user panel.
- What is the casing material and design?
- The casing is constructed with high-quality galvanized steel sheet for excellent corrosion resistance and outdoor durability. It features a clean, minimalist screw-less design that enhances aesthetic appeal and simplifies maintenance access.
- What certifications does this product hold?
- It is CE, ERP, and RoHS compliant, meeting European safety, environmental, and energy efficiency standards, ensuring market readiness for EU and other regulated markets.
- Is this product suitable for both residential and commercial projects?
- Yes. It is designed to meet the needs of homes, apartments, hotels, offices, and other light commercial applications requiring efficient heating, cooling, and hot water supply.
- Where can I get technical support or purchase spare parts?
- Please contact our sales team directly. FOSHAN JUYANG NEW ENERGY CO., LTD. provides full technical documentation, after-sales support, and genuine spare parts for all products.
