Sola Solar Pump-free household solar water heater is Open water tank for heat storage, closed coil for heat exchange. Sola Solar 20 second rapid heat exchange technology is adopted, The hot water is quickly ready to use, and the water quality is fresh. Moreover, the hot water pressure comes from the municipal cold water pressure, which matches with the cold water, so there is no sudden cold and hot, easy to adjust the water temperature. Sola solar pressurized hot water heater is with surging pressure, the water volume is sufficient, and bring you good use experience.
Pump-free centralized heat collection and storage - centralized solar water heating system without booster pump is a simple and reliable solution for commercial solar energy water heating system heat utilization. Our pump-free solar water heating system itself has zero energy consumption, maximizes the overall utilization of roof solar energy resources, has simple management and operation, convenient maintenance, and confined water. It can be smoothly connected with any conventional heat source, and the water quality is pollution-free, so as to meet the large hot water consumption or 24-hour water demand.
Advantages:
1. Coil heat exchange technology
Sola Solar pressurized fresh water solar water heater adopts RHEs reverse heat exchange technology. The open water tank is used to store heat energy, and the closed heat exchanger is used to exchange heat and take hot water. Pressurized water does not need to add booster pump, and the water quality is fresh without secondary pollution.
2. 20 second rapid heat exchange
With the rapid heat exchange technology developed by sola solar, cold water flows through the stainless steel bellows heat exchanger for 20 seconds and quickly turns into hot water. And the temperature difference between the water temperature and the heat medium after heat exchange is 2-5s . Moreover, the water quality is fresh, does not contain nitrite and Legionella, not easy to scale, and can be used as kitchen water.
3. Modular design and expandable water tank
Sola solar fresh water solar water heater adopts modular design, and the water tank can be expanded. It can be used in places with large water consumption and many water points.
4. Super blue titanium coated heat collector plate
Super blue titanium coating has the characteristics of high absorption, low reflection and no pollution. The "Super Blue Titanium Coating" coating is a high absorptivity coating that stores thermal energy inside the absorber while reducing reflections, maintaining emissivity.
5. The water quality is fresh and drinkable
Open water tank for heat storage, closed coil for heat exchange and water intake. The hot water quality is as clean as cold water in the closed coil. It can be used as kitchen water.
6. Constant water pressure
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.
7. Ease of use and maintenance free
The collector uses heat medium water without scaling; The heat exchanger adopts corrugated pipe floating heat exchange to take water, which is not easy to scale. The product is simple to operate and easy to maintain.
8. It can be connected with other energy sources
As a pre heating equipment, solar water heater can be combined with conventional energy (electric water heater, gas water heater, air source heat pump).
