The 35L solar shower is a large-capacity hot water shower suitable for outdoor use, ideal for providing continuous hot water to multiple people by the pool, in the backyard, or at outdoor gatherings. The shower is filled with water and then heated by sunlight, eliminating the need for solar panels or other auxiliary heating systems. It is an outdoor hot water solution that relies on natural sunlight for heating.
In terms of structural design, the shower is directly fixed to a hard surface with four expansion screws, or mounted on a matching base and placed on the ground, ensuring stability and wind resistance. This floor-standing installation method is simple and practical, making it particularly suitable for unprotected locations such as backyards or outdoor pools.
To adapt to seasonal usage, the shower is equipped with a dedicated drain port to drain accumulated water during winter when not in use, reducing the risk of water freezing and causing expansion damage to the pipe. This design, not found in all similar products on the market, demonstrates the device's reliability. Routine maintenance requires only regular draining, cleaning the shower pipe, and checking the seals at the showerhead and connections to ensure long-term stable operation.

READ MOREIn the realm of modern outdoor living, the accessibility of warm water significantly dictates the quality of backyard activities. As a professional manufacturer deeply rooted in the industry since 2010, Quzhou Haihong Electrical Equipment Co.,Ltd. focuses on merging environmental technology with outdoor aesthetics through innovative industrial design. Our 35L Capacity Solar Shower stands as a flagship representative of this philosophy.
The Advantage of High Capacity
Compared to common 20L models on the market, the 35L Capacity Solar Shower offers a substantial volume that drastically enhances the user experience. A 35-liter capacity ensures that after a single solar heating cycle, there is enough warm water to support 2 to 3 adults for full showers, or allow a whole family to rinse off sequentially after a pool session. This eliminates the frustration of frequent waiting periods for water to reheat, ensuring a steady supply of warmth. During family gatherings or summer parties, this high-capacity tank guarantees that every guest can enjoy a comfortable rinse before and after swimming.
Eco-Friendly Heating Principles
Leveraging over 15 years of R&D expertise from Quzhou Haihong Electrical Equipment Co.,Ltd., we have optimized the heat-collection coating of the water tank. The operational principle of the 35L Capacity Solar Shower is both simple and highly efficient:
High-Efficiency Absorption: The specially treated black cylinder is designed to absorb the maximum amount of UV radiation.
Greenhouse Effect: Heat is trapped within the sealed tank, causing the water temperature to rise steadily.
Sustainability: No connection to electricity or gas is required. By relying 100% on solar energy, it helps households save significantly on energy costs annually.

An exceptional solar shower is defined by its internal engineering. Quzhou Haihong Electrical Equipment Co.,Ltd. has applied several industry-leading technologies to the core components of the 35L Capacity Solar Shower to ensure high heat-collection efficiency and structural stability in extreme outdoor environments.
Advanced Heat-Absorbing Materials
Our R&D team developed a high-absorption coating system applied to high-density PVC or aluminum alloy cylinders. These materials possess excellent thermal conductivity, capturing over 90% of energy from the solar spectrum.
Thermal Lock Design: The internal tank structure is aerodynamically optimized to ensure that incoming cold water does not immediately dilute the hot water at the top.
Pressure Resistance: Our 35L tanks remain structurally sound under water pressures of up to $3.5 \text{ bar}$, far exceeding industry averages.
Intelligent Temperature Adjustment
To ensure safety and comfort, the 35L Capacity Solar Shower integrates a precise hot-and-cold mixing valve. Since the 35-liter internal temperature can rise above $60°C$ in direct sunlight, our valve system allows for smooth linear adjustment, enabling users to set the perfect temperature for their skin.
Corrosion Resistance and Longevity
We reinforce every detail for harsh outdoor conditions. Our brackets and internal pipes use food-grade, corrosion-resistant materials. This prevents rust and scaling even in humid pool environments or coastal areas with high salt spray concentrations.
