Product Description

SFA47155818 Compact Non Pressure Solar Water Heater
It is a non-pressure solar water heater system, which converts solar energy into heat energy and stores it in the insulated water tank. It is a natural circulation that relies on its own gravity to drain out of water from tank. As the tank can not bear any pressure so it is a open type water solar heater and generally also known as low pressure solar collector as well. Due to its convenience on installation and daily use, low cost, as well as to meet the hot water needs of normal households, this solar boiler is currently the popular product in the market.

Size of Product

SFA47205818 can produce 200L of 55℃-65℃ hot water per day for 5-6 people every day. This product is 100% solar energy, low cost and high efficiency. It is the most economical type among many solar water heaters.

Optional Accessories

Water supplier
Function: when water in the tank is reduced, help add water into tank automatically

The main function of the controller is to display the water temperature and water level in the water tank, and to automatically control the water supply of the hot water tank through the water temperature/water level/time period.

Magnesium rod
Protect the inner tank from corrosion. Magnesium's chemical properties is more lively and it has priority and corrosive substances chemical reaction so it can be effective corrosive substances in the barrel of the corrosion, to extend the life of the tank. Especially in high hardness water areas, we should often replace the magnesium rod.

Evacuated Solar Tube
Solar vacuum tube by AL/N/AL coating efficiently absorbs solar energy and converts it into usable heat, adopting the vacuum technique between the double-layer glass, which can effectively prevent the loss of heat, absorption rate is greater than 93% and the reflectivity is less than 8%. 


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.

Solar heat storage water tank
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.

Product Advantages

1. Perfect design, very suitable for family use.
2. The use of natural circulation, 100% solar energy and do not need to run cost.
3. Solar collector adopts a double-layer vacuum glass tube, high thermal efficiency and durable service life.
4. The use of plug-in connection between solar collector and insulation water tank and very easy to install.
5. Parts with low cost, no maintenance and no expensive maintenance costs.
6. The use of food grade stainless steel SUS304 manufacturing barrels, no pollution and no corrosion, to keep water quality clean and sanitary.
7. Using ultra-thick polyurethane insulation, a long time to keep the tank temperature constant.
8. Can be combined with the use of electricity, gas and other alternative energy.
