SFD47245818 is a pressurized solar water heater with a copper coil (heat exchanger), the water tank itself is not under pressure. A copper coil is placed inside the water tank, and the water flows through the coil and is heated by the hot water in the water tank. The use of non-pressurized water tanks reduces costs. Use a copper coil (heat exchanger) to get pressurized hot water, and the bath is more comfortable and relaxing.
SFD47245818 can be intelligently connected with gas water heaters to automatically control hot water effluent and maximize the use of solar energy.
SFD47245818 provides fresh hot water for safer and healthier use.




SFD47245818 can produce 240L of 55℃-65℃ hot water per day for 4-6 people every day. This product is 100% solar energy, low cost and high efficiency.It is the cleanest and most comfortable type of many solar water heaters.

SFD47205818 is a solar water heater unit with the lowest cost of obtaining high pressure hot water. Adding a copper coil device (heat exchanger) in the non-pressure storage hot water tank, the water flowing through the coil is heated by the hot water in the water tank, thereby providing high pressure fresh hot water, the bath is more comfortable and relaxed, and the use is safer. healthier.
SFD47205818 can be intelligently connected with gas water heaters to automatically control hot water effluent and maximize the use of solar energy.
SFD47205818 provides fresh hot water.

Affordable Price, High Adopt natural circulation, 100% solar energy, no running cost; low cost, no need for post-maintenance, safe use for fifteen years

The solar vacuum collector tube absorbs solar energy through a high-efficiency AL/N/AL coating and converts it into usable heat. The vacuum is applied between the double-layer glass to effectively prevent heat loss.

The bracket installation of solar hot water systems through a professional design of structural mechanics, which is not only solid and safe, but also easy to install. It's suitable to all kinds of roof structure and form, such as flat roof, sloping roof, tiled roof, metal roof and so on.

The solar water heater tank barrel adopts food grade stainless steel SUS304 material, good corrosion resistance, safe, non-toxic and no pollution. To protect the family with water safety and good health.
Solar water tank with automatic argon arc welding and argon double protection can effectively prevent the surface oxidation. Strict measures that control welding process can better protect SUS304 crystal structure not being destroyed. The service life of the barrel is more than 15 years.
Solar water tank with polyurethane insulation, good process and 55mm thickness, to ensure that the temperature drop of hot water is less than 2℃ within 12h.
1. Fresh pressure hot water, bathing is more comfortable and healthier.
