Swimming Pool Solar Water Heater: An Efficient Thermal Energy Solution With Flat-Plate Solar Collectors

Opening: Redefining the Comfort Experience of Swimming Pools

Today, in the pursuit of a healthy lifestyle and leisure and entertainment, swimming pools have become standard facilities in many families, hotels and fitness centers. However, the energy cost required to maintain a comfortable swimming pool water temperature is often prohibitive. Traditional electric heating or gas heating methods not only have high operating costs but also impose a considerable burden on the environment. Against this backdrop, solar pool heating systems, with their economic, environmentally friendly and efficient features, are becoming a wise choice for pool owners. 

As a professional manufacturer of solar thermal utilization, we are well aware of the special requirements for swimming pool heating. The flat-plate solar collector for swimming pools that we have launched is an innovative heating solution specifically designed for various types of swimming pools. It can significantly extend the swimming season while greatly reducing operating costs.

I. Core Technical Features of the Product

High-efficiency flat plate heat collection technology

1. Selective absorption coating is adopted, with a solar absorption rate of over 94% and an infrared emissivity of less than 6%;

2. The integral flow channel design features low water flow resistance and high heat transfer efficiency; 

3. Weather-resistant tempered glass cover plate, with high light transmittance and strong impact resistance.

Specialized materials and structures 

The core of the heat collection plate is made of high-strength aluminum alloy or copper-aluminum composite material, which has excellent corrosion resistance; 

The frame is made of anodized aluminum alloy, which has strong weather resistance and a long service life; 

The insulation layer is made of environmentally friendly polyurethane foam material, with low heat loss.

Optimized thermal performance 

It has a wide operating temperature range and is suitable for swimming pool heating requirements of 25-45℃; 

It has a high thermal efficiency, with an instantaneous efficiency of over 75% under standard test conditions; 

It has low pressure loss and can be used in combination with various types of water pumps.

Ii. System Composition and Working Principle

Main components of the system 

1. Flat-plate solar collector array 

2. Circulating water pump 

3. Automatic control system 

4. Filtering device 

5. Connect the pipelines and fittings 

Workflow 

The swimming pool water, after filtration, enters the collector 

It is heated by absorbing solar energy in the collector 

The heated water flows back to the swimming pool 

Repeat this cycle to gradually increase the water temperature of the entire swimming pool

Control mode 

Temperature difference cycle control: Automatically detect the temperature difference between the collector and the swimming pool water 

Timed control: Set the operation time period as needed 

Manual control: Start and stop the system manually as needed

Iv. Technical Parameters and Performance

Collector specification 

①Rated Efficiency: Calculated using the collector's instantaneous efficiency equation under 1000W/m² irradiance and a 50°C temperature difference between the collector and ambient air5.
②Rated Power: Derived from the product of rated efficiency, aperture area, and irradiance (1000W/m²) under the same temperature difference condition.

System performance 

The average daily heat gain per square meter of the collector is 5-8kWh 

Temperature rise capacity: It can increase water temperature by 3 to 8 degrees Celsius every day 

Applicable swimming pool volume: Each square meter of heat collection area can support 3 to 5 cubic meters of water

Installation requirements 

Installation inclination Angle: ±5° of local latitude 

Orientation: Within 15° south or west 

Installation space: Ensure there are no obstructions
