Exquisitely Meticulous Compact Pressurized School Home Hotel Commercial Heating System Solar Water Heater

Product Description

Exquisitely Meticulous Compact Pressurized School Home Hotel Commercial Heating System Solar Water Heater
Product Description Sola Solar Pump free solar water heater is Open water tank for heat storage, closed coil for heat exchange and water intake. Sola Solar 20 second rapid heat exchange technology is adopted. The hot water is ready to use, and the water quality is fresh. The hot water pressure comes from the municipal cold water pressure, which matches with the cold water. It is simple to adjust the water temperature. The pressure is surging, the water volume is sufficient, and the use experience is good.
Our Advantages No.1
The end cover of the solar water tank adopts flange connection, which can be opened and maintained at any time, making it safer and more convenient to use.
No.2
The solar energy solar heater adopts a modular design, and the water tank can be expanded to meet the needs of customers with large water consumption and many water usage points.
No.3
The rapid heat exchange technology developed by Sola Solar, cold water flows through the stainless steel bellows heat exchanger for 20 seconds to quickly turn into hot water. The water quality is fresh, and it can be used as kitchen water.
