Apollo 15 Tube Solar Water Heater 240L APOLLO 15 TUBE

Capacity: Typically 200 liters (sometimes marketed as 240L capacity), suitable for medium-sized households.

Tube Technology: Uses high-quality, high-efficiency evacuated tube collectors (often three-target vacuum tubes) for maximum solar energy absorption.

Inner Tank Material: The inner tank is constructed from corrosion-resistant SUS304 food-grade stainless steel, ensuring a long, rust-free life.

Outer Tank Material: Features a tough, pre-coated, corrosion-resistant zinc or stainless steel outer wrap for durability.

Insulation: Includes a high-density polyurethane foaming (PUF) insulation layer (around 50-60mm thick) which helps retain heat effectively for up to 72 hours.

Electric Backup: An electric heating rod with a thermostat is included, allowing for hot water supply during cloudy weather or low solar gain.

Durability and Resistance: The vacuum tubes are designed to be hail and freeze resistant, minimizing the risk of damage.

Maintenance: Designed with an additional drain outlet for easy tank cleaning and low overall maintenance needs.

Welding: Utilizes Argon Arc welding for secure and long-lasting connections at all outlets and vents.

System Type: Typically an integrated non-pressurized thermosiphon system, which circulates water naturally without the need for additional pumps.

Warranty: Often comes with a 5-year warranty
