The Hanti JPH 20 Heat Pipe Direct Pressurized Solar Water Heater, 200L is a sophisticated and highly efficient solution for providing hot water using the power of the sun. Designed for reliability and performance, this system combines advanced heat pipe technology with a direct pressurized design, making it suitable for a wide range of residential and light commercial applications. It offers a substantial 200-liter (approx. 53 gallons) hot water capacity, ensuring ample supply for households of varying sizes.

At the heart of the system are the high-vacuum heat pipe solar collectors. These collectors feature double-glass vacuum tubes, each containing a copper heat pipe. The inner absorber coating (typically AL-N/AL or similar) efficiently captures solar radiation, heating a small amount of fluid (usually ethanol or a similar medium) within the heat pipe's sealed end. As this fluid heats up, it rapidly vaporizes and rises to the top of the heat pipe, where it transfers its heat to the manifold. The vapor then condenses back into liquid and, under gravity, flows down to the base of the heat pipe, ready to repeat the cycle. This phase-change process offers extremely fast heat transfer with minimal heat loss, even in colder conditions.

The system operates in a direct pressurized manner. Cold water from the municipal supply enters the specially insulated stainless steel storage tank directly. As the solar collectors heat the water within the tank throughout the day, the water temperature rises. The pressurized design means the system operates at mains water pressure, delivering a consistent and comfortable flow of hot water directly to your taps, showers, and appliances, just like a conventional water heater, without the need for a rooftop storage tank.

The 200L capacity stainless steel tank is designed for durability and longevity. It features a robust outer casing and high levels of insulation (often polyurethane foam) to minimize heat loss, keeping water hot for extended periods even when the sun isn't shining. An integrated electric backup heating element is typically included, providing peace of mind by ensuring hot water availability during extended periods of cloudy weather or high demand, seamlessly switching to solar operation when conditions improve. The system often includes features like a pressure relief valve, temperature & pressure gauge, and potentially a digital controller for monitoring and managing system functions.

Installation is generally straightforward, designed for roof mounting (flat or pitched). The direct pressurized nature simplifies plumbing integration with existing household water systems. Overall, the Hanti JPH 20 offers an eco-friendly, cost-effective, and reliable way to harness solar energy for domestic hot water needs, significantly reducing reliance on conventional energy sources and lowering utility bills.
