High Efficiency & Zero Operating Cost
Utilizing natural thermosiphon circulation, the system requires no circulation pump or electronic controller, eliminating both energy consumption and pump maintenance costs. High-efficiency evacuated tube collectors achieve over 70% thermal efficiency, significantly reducing household electricity bills for water heating while delivering reliable hot water performance year-round.
Premium Durability & Safe Water Quality
The inner tank is constructed from food-grade SUS304 stainless steel, offering excellent corrosion resistance, anti-rust properties, and hygienic water storage. High borosilicate glass evacuated tubes withstand thermal shock, hail impact, and extreme temperatures, ensuring a long service life. Multiple capacity options from 100L to 300L accommodate various family sizes and hot water demands.
Flexible Installation & Scalable Supply
Engineered for both pitched and flat roof installations, the compact design simplifies mounting and integrates seamlessly with diverse residential architectures. Manufactured in an 80,000ใก automated facility, these units guarantee consistent quality and stable output. We welcome bulk orders and offer OEM customization to support global distributors and project contractors with reliable partnership solutions.
