the 500liter commercial solar water heater with a 50 tube manifold solar collector, daily hot water capacity is 500liter, suitable for small hotels.
Why Manifold ETC solar water heaters?
The Manifold ETC solar water heater system stands out from traditional solar water heaters due to its unique design and advanced technology. Unlike flat-plate collectors, evacuated tube collectors (ETCs) consist of individual glass tubes with a vacuum-sealed inner layer, eliminating heat loss through convection. This design allows them to:
Capture more sunlight: Even on cloudy days, solar evacuated tube collector absorbs diffuse radiation, ensuring consistent hot water supply.
Work in extreme temperatures: From hot summers to mild winters, ETCs maintain efficiency without freezing or overheating.
Maximize space utilization: The manifold solar collector design allows for modular expansion, making it ideal for large-scale commercial installations, it could be installed on the flat ground or rooftop.
A 500liter solar water heater meeting the demands of commercial environments. Whether it is a hotel, hospital, restaurant, or school, this system ensures:
High-volume hot water: Enough for multiple showers, kitchen operations, or sterilization processes without interruption.
Energy savings: Cut electricity costs by up to 70%, freeing up funds for other business priorities.
Long-term durability: Food-grade stainless steel tanks and corrosion-resistant coatings withstand Zimbabwe’s climate, ensuring decades of service
The ETC solar water heater adopts solar vacuum tube technology, the solar evacuated tube collector absorber will collect heat from the sunlight and transfer into water inside the tubes. The tube water is heated to rise up and tank cold water sink down to creat a circulation, called thermosiphon effect. The water tank will be gradully full of hot water as the tubes keep collecting heat from the sunlight. It is no need of electricity heating. It is only by solar thermal heating.
