China supplies CE approved assured quality evacuated glass tubes solar hot water heater
Compact non pressure solar water heater relies on the nature circulation of the water between solar tubes
and the water tank. Thermosyphon systems work on principal of heat rising. The water enters in the bottom
of the collector and rises to the tank as it warms. The advantage of this system is that solar heat is stored
in a well-insulated tank, so hot water can be used at any time without the penalty of overnight losses.
Moreover the insulation of the tank can protect heat during 3 days without heat loss.
1.Features:
(1). Cheap and reliable solution, Simple structures, Easy installation.
(2). High efficiency of heating,water heated by sun light directly.
(3). Withstands water pressure no more than 0.1MPa.
(4). Operated without any power supplying.
(5). Electric heater can be used as back-up in rainy days.
(6). Hot water can be used directly, or can be used as a pre-heated.
(7). Water flow in the vacuum tubes and is operated when confined.
(8). Tank is equipped with electric water heater setting, automatic temperature controller(optional ).
(9). the insulating layer uses polyurethane bulk bubble,keep hot water 72 hours.
2.How to choose:
Choose the item according to the capacity, and choose the capacity according to the people quantity
in your family, one adult shower need about 50 L water. Normally,50 liters is only used for one person's shower.
