Hiounce Domestic Instant Gas Water Heater Series

This unit features a clean, elegant overall design complemented by left and right 90° curved glass panels—delivering a premium, timeless aesthetic that seamlessly integrates into modern living spaces. Precision craftsmanship and structural stability ensure both visual appeal and long-term reliability, while enhancing daily usability.

Powered by a 5th-generation microcomputer processing chip, the system continuously monitors real-time water temperature, flow rate, and user-set temperature to achieve stepless flame modulation—ensuring intelligent constant-temperature performance (stable outlet water temperature regardless of flow fluctuations) and minimizing seasonal temperature variations.

The intelligent 4-stage combustion technology and sealed, enhanced combustion system enable automatic power-level switching for superior thermal stability—minimizing temperature deviation, maximizing energy efficiency, and reducing operational noise. Combined with the high-resistance exhaust system, weld-free construction, and oxygen-free copper (TP2) straight-tube heat exchanger, the unit delivers exceptional durability, corrosion resistance, and consistently reliable, comfortable, hassle-free hot water for household use.

Gas Water Heaters
  • Streamlined, elegant overall design with exquisite craftsmanship
    The left and right 90° curved glass panels deliver a premium, sophisticated appearance—timelessly stylish and modern.
  • Intelligent constant-temperature control system
    Equipped with a 5th-generation microcomputer processing chip, the system dynamically adjusts flame intensity based on real-time water temperature, flow rate, and set temperature—achieving stepless flame modulation for intelligent constant-temperature performance (stable outlet water temperature regardless of flow changes), unaffected by seasonal variations.
  • Intelligent 4-stage combustion technology
    Features intelligent 4-stage combustion combined with a sealed, enhanced combustion system. Automatically switches between power levels for precise thermal control—combustion system temperature variation within ±1°C—ensuring high efficiency, energy savings, and lower operating noise.
  • High-resistance exhaust system
    Utilizes large-diameter riveted duct construction—weld-free design—for exceptional durability, resistance to joint failure, and reduced operational noise.
  • Oxygen-free copper (TP2) straight-tube heat exchanger
    Features an oxygen-free copper (TP2 material) straight-tube heat exchanger—20% higher thermal conductivity, robust construction, and long-term corrosion resistance.
