150l Solar Water Heater

I. Product Introduction

The pressurized flat pane insulated tank solar water heater (Pressurized Flat Pane Insulated Tank Solar Water Heater) is an ideal choice for energy-saving hot water solutions in modern households and commercial buildings. This product adopts a split design, consisting of a flat collector and a pressurized water storage tank. Unlike traditional vacuum tube solar systems, its collector is a perfect combination of high-strength aluminum alloy frame and low iron fabric tempered glass. It not only has a fashionable appearance and integrates seamlessly with the building roof, but also possesses efficient heat absorption performance and pressure-bearing operation capabilities. 

This series of products is specially designed for high-rise residences, villas and hotels. They support pressurized top-water operation and have a strong water output similar to that of tap water, solving the problems of small water output and uneven heating in traditional solar water heaters. The enamel inner tank water tank has excellent corrosion resistance, ensuring the stability and hygiene safety of the product during long-term use.

III. Working Principle

Pressure-type flat plate solar water heaters operate based on either forced circulation (split type) or natural circulation (compact type) principles. The system consists of flat plate collectors, water storage tanks, circulation pumps and intelligent controllers. 

1. Thermal-to-light conversion: Sunlight passes through the low iron tempered glass of the flat collector and is directed onto the highly selective heat-absorbing coating. This coating efficiently converts solar radiation energy into thermal energy, heating the copper tubes and medium (special antifreeze or water) inside the collector. 

2. Circulating heat transfer: When the difference between the temperature of the collector and the temperature of the water tank reaches the set value (usually 5-10℃), the intelligent controller automatically starts the circulating pump. The heat in the collector is forced to circulate through the medium to the jacket or built-in coil of the water tank, thereby heating the domestic water in the water tank. 

3. Pressure-assisted water supply: The water tank is a fully enclosed pressure-bearing structure that is directly connected to the water supply pipeline. When the user turns on the hot water faucet, under the pressure of the tap water, the hot water at the top of the water tank is pushed out, achieving constant temperature and pressure water supply. 

Intelligent Assistance: In rainy or low-light conditions, the system can automatically activate the built-in electric auxiliary heating function to ensure continuous hot water supply 24 hours a day. 

IV. Product Advantages

1. Resistant to pressure, high comfort level

As a Pressurized Solar Water Heater, this product directly utilizes the pressure of tap water for water supply. The water output has strong impact force, and the temperature adjustment is simple. It completely eliminates the awkwardness of traditional solar water heaters' "dripping trickle" water flow. 

2. High-efficiency heat collection, stable performance

Using all-copper core flat plate collectors, combined with the highly absorbent blue titanium coating, it still performs well even under cloudy and low-light conditions. The flat plate structure is not prone to scaling or dust accumulation, and the maintenance cost is extremely low. 

3. Building Integrated Photovoltaics (BIPV)

The flat collector has a smooth and streamlined appearance and can be installed by embedding it into the roof or balcony railings. It is the best choice for modern high-rise buildings to achieve the integration of solar energy and architecture. 

4. Durable and anti-corrosive, with clean water quality

The enamel inner tank water tank has extremely strong anti-corrosion ability and does not pollute the water quality. It complies with drinking water hygiene standards. Combined with the polyurethane high-pressure foaming insulation layer, the insulation effect is outstanding, with a temperature drop of only 3-5℃ within 24 hours. 

5. Intelligent control, safe and reliable

The system is equipped with multiple protection functions: anti-freezing protection, anti-dry-burning protection, leakage protection, high-temperature protection, etc. It can operate stably regardless of extreme cold or heat. 

V. Factory Advantages

Our company, as a professional manufacturer of solar water heaters, has over 15 years of experience in the research and production of solar thermal products.

VIII. Application Cases

1. High-rise Residential Project: Install flat-plate pressure-bearing solar hot water systems for individual households. Suitable for flat roofs and pitched roofs, they are both aesthetically pleasing and practical, and are environmentally friendly and energy-efficient. 

2. Hotel Engineering: For the resort hotel, a pressurized flat plate solar hot water system was adopted. Large-area flat plate collectors were installed on the roof, combined with air-source heat pumps for assistance. This solution addressed the issue of centralized hot water supply during the peak tourist season, with an investment return period of only 2.5 years. 

3. Overseas villa: In the villa area, a large-capacity Pressurized Solar Water Heater was selected to meet the daily bathing needs of 5 bedrooms and the heating requirements for the swimming pool. Customers reported that the system operates stably with zero malfunctions and has been running for over 4 years without any issues. 

VII. Installation Precautions

1. Collector orientation: The collector should face due south or 15 degrees west of south to ensure the optimal sunlight angle. The installation location should avoid any shading objects. 

2. Placement of water tank: The water tank is usually placed on the indoor balcony, equipment room or basement. It is necessary to ensure the ground's load-bearing capacity and reserve a drainage floor drain. 

3. Pipeline connection: The circulation pipeline is recommended to use copper pipes or PEX pipes, and strict insulation treatment (with insulation cotton thickness not less than 20mm) should be carried out to reduce heat loss. 

4. Anti-freezing measures: In cold regions, the system must be filled with antifreeze and equipped with a low-temperature circulation protection function to prevent pipeline freezing and cracking. 

5. Electrical safety: Grounding wires must be installed, and ensure that the leakage protection switch is functioning properly. Electrical maintenance must not be carried out when the power is off. 

IX. Development Trends

With the global emphasis on energy conservation and emission reduction and the advancement of the "dual carbon" goals, the solar water heating industry is moving towards a direction of high-endization, intelligence, and integration with buildings. 

1. Efficient flat panels replace vacuum tubes: Due to the advantages of flat collectors in terms of appearance, pressure-bearing capacity and safety, flat solar energy is gradually becoming the mainstream choice for urban high-rise buildings, especially in the European and North American markets, where its market share continues to rise. 

2. Multi-energy complementary system: The single solar water heater is transforming into a multi-energy complementary system such as "solar energy + heat pump" or "solar energy + gas/electricity". Through intelligent control, solar energy is given priority use, and the insufficient part is supplemented by clean energy to achieve stable supply throughout the year and all day long. 

3. Intelligence and the Internet of Things: Future products will be equipped with Wi-Fi modules. Users can remotely monitor water temperature and volume through a mobile app, control the auxiliary heating time, and monitor the system's operation status in real time, achieving visual and intelligent management of energy. 

4. New material application: The research and development of phase change energy storage materials and new selective heat-absorbing coatings will further enhance the heat collection efficiency and energy storage density, enabling the product to achieve longer endurance capabilities while maintaining a smaller size. 

5. Summary: Choosing our pressurized flat pane insulated tank solar water heater is not merely selecting a water heating device, but rather opting for an environmentally friendly, comfortable and safe lifestyle. We look forward to establishing long-term partnerships with global customers and jointly promoting the application and development of green energy.
