500L Air-Source Heat Pump

1. Core Capacity and Water Supply Performance

Supports continuous bathing for 6–8 people, with multiple-point supply (multiple bathrooms + kitchen) and 24/7 constant temperature.

Commercial-grade high flow rate – Suitable for concentrated water-use scenarios such as B&Bs, hair salons, small hotels, and gyms, ensuring adequate supply during peak hours.

Pressurized / Stratified heat storage – The pressurized tank ensures stable water output; the dual-chamber stratified design prevents mixing of hot and cold water, maintaining a consistent outlet temperature.

2. Energy Efficiency and Heating Performance (Core Advantages)

Class-1 energy efficiency, COP ≈ 4.0–4.2 – Saves 75%–85% electricity compared to conventional electric water heaters, significantly reducing annual energy costs.

Inverter / Dual-inverter technology – Inverter compressor and inverter fan automatically adjust power output based on water temperature and ambient conditions, ensuring higher efficiency even at low temperatures.

Efficient heat exchange – Micro-channel external coil / tube-in-tube heat exchanger, corrugated / gold-fin evaporator with large heat exchange area and fast defrosting capability.

Low-temperature adaptability – Most models operate stably down to –10°C; electric auxiliary heating is available on select models for reliable performance in northern winters.

Eco-friendly refrigerants – R32 / R410A / R134A, featuring high efficiency, low GWP (Global Warming Potential), and zero ozone depletion potential.

3. Safety and Durability

Water-electricity separation + multi-layer protection – No direct electric heating in water; equipped with 10–16 safety protections including dry-burn prevention, overpressure, overcurrent, overtemperature, freeze protection, and leakage protection.

High-quality tank construction – Three-layer enamel tank, titanium-gold tank, or stainless steel tank with dual magnesium anodes, offering excellent corrosion resistance, scale resistance, and burst protection. Tank warranty: 5–8 years.

Superior insulation – 50–55 mm high-density foam with 360° heat retention; maintains usable hot water for up to 72 hours during power outages.

Robust overall durability – Compressor and fan vibration dampening, anti-corrosion coating, and commercial-grade design ensure extended service life.
