The BTE Solar Heat Pipe Split System seamlessly integrates solar energy with modern architecture, providing you with 24-hour, constant-temperature, comfortable hot water.


Detailed Product Description

I. Product Overview

The Heat Pipe Solar Split System is a high-performance hot water solution that represents cutting-edge technology. Its innovative "split" design completely separates the collector from the water storage tank, completely resolving the challenges of traditional solar water heaters, such as installation limitations, aesthetic issues, and long cold water runs. The system utilizes highly efficient "heat pipe" vacuum tube technology, resulting in extremely high heat collection efficiency. Even in cold winters or on cloudy days with weak sunlight, it can consistently provide sufficient hot water, perfectly meeting the high-quality hot water needs of modern homes, villas, hotels, schools, and other locations.

II. Core Working Principle

1. Heat Collection Process: Vacuum collector tubes installed on balconies, exterior walls, or rooftops efficiently absorb solar radiation using their built-in "heat pipes." The special working fluid within the heat pipe rapidly evaporates and rises to the condensing end at the top.

2. Heat Exchange Process: At the condensing end, the high-temperature working fluid vapor rapidly transfers heat to the coil heat exchanger within the water storage tank via the built-in copper heat exchanger rods.

3. Circulation and Heat Storage: After the cold water in the water tank is heated by the coil, it circulates throughout the tank through natural convection (or forced circulation), ultimately raising the temperature uniformly throughout the tank. After releasing heat, the working fluid in the heat pipe condenses into liquid and flows back to the bottom of the heat pipe, beginning the cycle again.

4. Advantage of the Split-Type System: The water storage tank can be flexibly installed indoors (such as in bathrooms, balconies, and kitchens), achieving spatial separation between heat collection and storage.

III. Core System Components

1. Heat Pipe Vacuum Collector

Evacuated Glass Tube: Made of high-borosilicate 3.3 glass with a transmittance of ≥91%, it features a high-efficiency selective absorption coating (absorptivity ≥0.94, emissivity ≤0.06), significantly reducing heat loss from radiation.

High-efficiency heat pipes: Core heat transfer elements with low starting temperatures and extremely fast heat transfer, far exceeding the efficiency of ordinary all-glass tubes. "Freeze-proof, Sun-proof"—no freezing in severe cold, no damage from air drying.

Insulated collector box: Aluminum alloy exterior for aesthetics and corrosion resistance; high-density polyurethane foam insulation inside to ensure heat is not lost.


2. Pressure-bearing insulated water storage tank

Inner liner: SUS304-2B food-grade stainless steel for corrosion resistance and clean water quality.

Insulation: Ultra-thick polyurethane foam over 50mm for constant temperature insulation, with a heat loss rate of less than 3% per day.

Coil heat exchanger: Made of 99.9% oxygen-free copper, highly efficient and corrosion-resistant, completely isolated from the system's circulating water, free of scale and contamination, for a longer lifespan.

Multi-energy interface: Standard electric heating auxiliary function interface easily handles continuous rainy weather and ensures 24/7 hot water supply.


3. Intelligent Control System

Fully Automatic Operation: The LCD display shows real-time water temperature, water level, and heating status.

Smart Start/Stop: Set heating temperature, timer, and automatic water filling for energy savings and peace of mind.

Multiple Protections: Features include leakage protection, dry-boiling protection, overheating protection, and low-temperature frost protection for worry-free operation.

Remote Control: Optional Wi-Fi module allows for remote monitoring and operation via a mobile app.

IV. Product Advantages and Features

1. Flexible Installation, Elegant Design: The collector can be laid flat, hung diagonally, or embedded, perfectly integrating with building facades. The water tank can be placed anywhere in the room, eliminating the need for "bulky" rooftop water heaters and enhancing the overall quality of the building.

2. Energy Efficiency, Worry-Free: Leveraging free solar energy, the system can achieve energy savings of up to 90% compared to electric water heaters, significantly reducing household energy costs and delivering a high return on investment.

3. Four Seasons of Worry-Free, Stable Performance: Heat pipe technology ensures the system operates normally in temperatures as cold as -30°C, offering exceptional frost resistance. Vacuum insulation allows the system to absorb heat even in dim sunlight.

4. Pressure-Resistant Operation, Comfortable Bathing: Water pressure matches tap water pressure, providing a powerful flow and the ability to connect to multiple outlets for a truly indulgent, spa-like bathing experience.

5. Safe and Reliable, Risk-Separated: Water and electricity are completely separated, eliminating the risk of electrical leakage. The collector prevents scaling, and the water tank is indirectly heated via the coil, ensuring cleaner water quality.

6. Smart Control, Convenient and Worry-Free: One-touch operation, automatic operation, and remote monitoring support make it an ideal choice for modern smart homes.
