Supplier's note

1. Technical Breakthroughs:

   • Evacuated tubes: Triple the thermal retention of flat-plate systems, enabling efficient heating even in low-light conditions.
   • Stainless steel housing: Resists corrosion 2x longer than aluminum, extending lifespan in marine or industrial environments.
   • Thermosyphon + active hybrid: Combines passive efficiency with active circulation, boosting output by 20% compared to single-mode systems.

2. Version Selection Guidance:

   • Base Model: Perfect for households or small hotels needing 80L/day. Its unpressurized design ensures safety in low-pressure grids.
   • Advanced Model: Hotels or offices with medium demand (120L/day) benefit from higher pressure resistance and hybrid backup compatibility.
   • Pro Model: Commercial complexes or large resorts require the 200L capacity and IoT monitoring for real-time performance tracking. The Pro’s 0.3 MPa pressure handles high-demand scenarios without system strain.

With the Pro version’s 0.3 MPa pressure rating—50% above industry standards—you can safely supply hot water to multiple faucets simultaneously. Pair this with its borosilicate tubes to maintain efficiency even in cloudy climates, ensuring uninterrupted service year-round.
