solar water heater: low price and good quality. low pressure
Characteristics:
1. Use copper coil in the tank as the heat exchanger
2. Take advantage of tap water's pressure
3. Produce hot water with constant tempreture, safe and comfortable
4. Water can be heated rapidly
5. Produce more hot water than the general type
Feature:
1. The design of this type production is according with the international market, Adopted copper coil as heat exchanger. And it is easy to installation and operation. 2. It can provide hot water with constant temperature, it is safe and more comfortable. 3. It can supply high quality hot water, and water can be heated rapidly. 4. It can produce more hot water than general types because it isn't restricted by capacity of tank. 5. It can be used single or many cells as solar heat system.
