Flat plate solar water heater is a combination of flat solar collector, non-pressurized water tank and automatic controller.

Sunbase flat plate solar collector consists of absorber, cover glass, insulation, and shell. The metal absorbing plate with coating is welded on the red copper pipe. The cold water or the medium liquid is heated when running through the pipe. The transparent cover glass allows visible light to pass through and blocks the far infrared. It means the sunlight can pass the cover glass and reaches the absorber to produce heat, but the far infrared resulted from the radiation of heated absorber is blocked and kept inside. In this way, the heat loss is reduced. And the heat-absorbing efficiency and the temperature of the absorber can be increased. There are usually three kinds of coatings: anodizing, black chrome coating and blue titanium coating. In areas with winter temperature above 0 °C, system of direct-heating of cold water is applicable, but in areas with winter temperature below 0 °C, the user could input medium liquid in the system to heat up cold water indirectly as an alternative.

flat plate solar water heater (MRCS) includes flat plate solar collector and pressurized water tank. It's a compact system

Specification of flat plate solar collector

1. Low iron textured tempered glass (3.2mm thickness) offers the best capability of durability, strength.

2. Anodic oxidation and nickel plating coating have very high absorption rate to ensure the high efficiency.

3. Since there are no adhesive or mechanical joints, nothing will deteriorate with age and high temperature.

4. Special Anodized aluminum alloy frame to ensure handsome appearance and can accept high pressure without leakage.

Specification of pressurized water tank

1. Inner tank: SUS 304-2B food grade stainless steel

2. Outer tank: color steel or SUS 304 stainless steel

3. Capacity: 100L, 150L, 200L, 250L, 300L

4. Testing pressure: 8 bar

5. Heat preservation: 72 hrs
