With the time goes by, more and more people choose solar products. Solar water heater as a typical solar product, nowadays is popular and widely used for different areas, such as home, school, factory, hospital, industry, swimming pools and so on. Solar energy is free, so as a homeowner or project engineer, it is a wise choice to adopt solar water heating system, but with so many solar hot water supplier to choose from, it can be difficult to distinguish one system from another. Reasonable prices, quality design, Rich experience, and Superb customer service are what making Sunflower Solar the right choice for solar water heating systems.
| Non-pressurized | Pressurized | |
| Model | ||
| Mounting position | Install on the roof, take advantage of the potential energy from the height difference of roof and room, make water come out with pressure | Any place which face sunshine |
| Water out pressure | Depend on the gravity of water | Equal to the water pressure from City water supply |
| Cold resitance | minus 5°C | minus 35°C |
| System | Water in vacuum tube, if one tube broken, need to replace it, then the system could work. | Adopt heat pipe technology, no water on tube, if one tube broken, the system could also work |
| Price | Cheap | Expensive |
Follows are the brife description for different solar water heaters from Sunflower Solar
