Detailed introduction: we usually call this item as normal solar water heater, it is the traditional specification, simply, inexpensive, used widely.
*effective and applicable: it adopts the efficient AL-N/AL heat absorption coating vacuum tube. It has high absorptivity,low emission rate.
*Scientific and reasonable design: water inlet and outlet are located in the lower parts of water tank, which is very installed, and can reduce the heat loss. And there is no dead angle area inside water tank to reduce the pollution.
*Superior material: use high quality borosilicate glass vacuum tube as heating collector; inner tank is made of SUS304 food grade stainless steel,welding for shaping, and outer shell is made of nacre white armor plate, which makes this SWH with such feature as strong corrosion-resistance, long life, no water pollution etc.
*Strong insulation: high density integral polyurethane foam,super thinkness insulation layer, to protect heat loss in water tank
*All-weather hot water supply: it may be installed with the auxiliary heating systems according to requirements, so we can use the hot water all days,even cloudy, or rainy days.
*Economical and environmental protection: the product’s longlife can reach 15 years, it is energy saving and non-pollution, protect environmental effectively.
*Very practical: large amount of hot water supply, it is very practial in daily life, can be used for shower, cleaning, and clothes, vegetables washing. If many SWHs are linked, it will be suitable for heat water projects, such as schools, hospitals, or other whole building.
