200L Thermosyphon integrated solar hot water heater
The 200L thermosyphon solar hot water heater with solar vacuum tubes is a non pressure integrated solar hot water system designed for normal households of 5 persons, to provide free hot water all year around.
The 200L solar water heater is designed for medium-sized homes or small businesses, serving up to 5 people. The system is versatile, capable of being installed on both flat and pitched roofs, ensuring flexibility for various building types. The high-quality materials, including 304 stainless steel for the inner tank and galvanized steel for the outer shell, ensure long-lasting durability and optimal performance.

1. solar vacuum tubes absorbs heat from sunlight, max temperature will reach 250℃ inside vacuum tubes.
2. integrated solar water heater system, all unit is put on rooftop , easy installation
3. water tank inside material is stainless steel 304 2B, food grade.
4. Thermal Insulation: High-density polyurethane foam insulation minimizes heat loss, maintaining water temperature overnight. The tank’s temperature retention exceeds 72 hours in optimal conditions.
