[Abstract]

Among the Pressurized solar water heaters, because both preheating Solar Water Heater with Copper Coil and Integrated Pressurized Solar Water Heater can bring pressurized hot water, many people cannot tell the difference between the two and the difference in price, which will cause many doubts. The following describes the difference between the them, you can also refer to the following two URLs for a detailed introduction of the two products:

[Main body]

1. From the type:

The same point:

Preheating Solar Water Heater with Copper Coil and Integrated Pressurized Solar Water Heater absorb light energy through AL/N/AL/SS/CU coating, and convert light energy into heat energy stored in the insulated water tank; all rely on a domestic solar water heater that actively performs natural circulation by virtue of the thermosiphon principle.

 

Difference point:

The water tank of the preheating Solar Water Heater with Copper Coil itself is open type non-pressure, and the inner wall of the water tank is thin, but through the copper coil built in the water tank,the water tank is only used as a heat storage medium, When the tap water is heat exchange immediately when the tap water passes through the copper coil, to achieve the purpose of utilizing fresh high-pressure hot water.

The water tank of the pressurized solar water heater itself is enclosed and pressurized. The water tank is designed with a pressurized structure, and the inner wall of the water tank is thick.

The test pressure is 9 bar, the working pressure is 6 bar, and it has a good protection device. There is pressure in the water tank itself. After the water in the water tank is heated, the hot water coming out is directly high-pressure hot water.

2. From the pressure of the water:

Preheating Solar Water Heater with Copper Coil and Integrated Pressurized Solar Water Heater are all the hot water effluent pressure is high and the pressure is equal to the tap water pressure.

 

3.From the water tank:

Preheating Solar Water Heater with Copper Coil adopts an open type non-pressure water tank. The water tank itself is not under pressure. It is connected to the air and inner wall thin . However, the copper coil is built in, and the heat is exchanged through the copper coil. Tap water is heated through the copper coil ,thereby bringing high pressure hot water.

The Pressurized Solar Water Heater adopts a closed pressurized water tank. The water tank is closed and not connected to the air. The test pressure is 9 bar, the working pressure is 6 bar, and the inner wall is thick. The water in the water tank is heated by the secondary exchange of the solar heat pipe collecting tube. Because of there is pressure in the water tank itself, Therefore, the hot water coming out is high pressure hot water.

4.From the solar collector tube:

The Preheating Solar Water Heater with Copper Coil adopts a solar vacuum collector tube,Since the water tank is open type, the vacuum tube communicates with the water tank, and the water in the tube is directly heated under the sunlight, and the natural circulation is stored in the insulated water tank.

The difference between Preheating Solar Water Heater with Copper Coil and Integrated Pressurized Solar Water Heater-7


The Pressurized Solar Water Heater adopts the solar heat pipe heat collector tube. Since the water tank is closed type, the heat pipe collector tube does not communicate with the water tank, and the solar heat pipe collector tube has no water, and the collector tube has the advantages of high heat transfer speed and high heat efficiency. Using a phase change heat transfer design,the second exchange is performed, and the solar vacuum tube is used for heat absorption, and the heat pipe transfers heat to heat the water of the water tank , is stored in the heat preservation water tank.

5.From the applicable area:

The Preheating Solar Water Heater with Copper Coil in areas with low latitudes and high temperatures, such as Puerto Rico, Jamaica, Indonesia, etc., people directly use SFD solar water heaters for bathing. However, in high-latitude and low-temperature areas, such as South Korea, Denmark, Poland, etc., people often use SFD products as preheating equipment, combined with gas water heaters, to provide medium-temperature hot water for bath, kitchen or heating floor heating.

The Pressurized Solar Water Heater adopts the heat pipe heat collector tube, has strong anti-freezing ability, and has good anti-freezing effect on the physical structure. Under the ambient temperature of -35 ° C, the heat pipe will not be frozen. It is especially suitable for high-latitude, cold and low temperature areas.

 

6.From the price point of view:

There are differences in the structure of the water tank and the heat collecting tube between the Preheating Solar Water Heater with Copper Coil and Integrated Pressurized Solar Water Heater, so the price will be different.

The Preheating Solar Water Heater with Copper Coil are cheaper than Pressurized  solar water heaters, and the Preheating Solar Water Heater with Copper Coilcan also provide high-pressure hot water.

[Conclusion]

All in all, The Preheating Solar Water Heater with Copper Coil and Integrated Pressurized Solar Water Heater can provide high-pressure hot water. If you want to choose a solar water heater that can provide high-pressure hot water, you can consider it from here , according to the applicable region, price, and structure to make a purchase.
