Solar Geyser

ETC stands for Evacuated Tube Collector, which is a type of solar thermal collector used to harness solar energy for heating water or other fluids. Here's an overview of Warm Stream’s ETC solar collectors:

How Warm Stream ETC Solar Water Heating System Works:

✅ Evacuated Tubes: This system consists of evacuated glass tubes with a selective absorptive coating on the inner surface.

✅ Heat Absorption: Sunlight enters the evacuated tubes and strikes the absorber coating, which absorbs solar energy and converts it into heat. The heat is transferred to the fluid (usually water or a heat transfer fluid) flowing inside the absorber tube.

✅ Direct Heat Transfer: In an ETC system, the heat transfer fluid (often water) flows directly through the absorber tube. As it absorbs heat from the absorber coating, the fluid becomes hot and rises naturally due to convection.

✅ Circulation: As the heated fluid rises, it is replaced by cooler fluid from the bottom of the collector, creating a natural circulation loop. This circulation continues as long as sunlight is available, transferring heat from the collector to a storage tank or heat exchanger.

✅ Storage Tank: The heated fluid is collected and stored in a well-insulated storage tank, where it remains hot until it is needed for domestic or industrial use.

Key Features of Warm Stream ETC Solar Water Heating Systems:

✅ High Efficiency: ETC collectors are highly efficient at capturing solar energy, even in diffuse sunlight conditions.

✅ Simple Design: ETC systems have a relatively simple design making them cost-effective and easy to install.

✅ Reliable Performance: Despite their simplicity, these systems offer reliable performance and can provide hot water even on cloudy days or in cold climates.

✅ Low Maintenance: With minimal moving parts and simple design, ETC collectors require low maintenance and have a long service life.

✅ Environmentally Friendly: By harnessing renewable solar energy, these systems help reduce reliance on fossil fuels and lower greenhouse gas emissions, contributing to a cleaner and more sustainable environment.

Overall, Warm Stream ETC solar water heating systems offer a cost-effective and reliable solution for meeting hot water needs in various settings. They provide an efficient alternative to conventional water heating methods while reducing energy costs and environmental impact.
