WORK PRINCIPLE:

A copper coiler with 20 - 50 meters length is installed in water tank as the heat exchanger. When water flows into the copper coiler, it absorbs the heat from the water in the storage tank, so it can bear much higher pressure, there will be a strong and more comfortable shower. Without the tank directly transferring, the water is more clean and healthy.

DESCRIPTION:

1). Inner tank: stainless steel SUS304-2B (0.4mm-0.5mm)

2). Outer tank: galvanized / color steel / stainless steel

3). Frame: galvanized steel with plastic spray / stainless steel

4). Insulation: 50mm-60mm polyurethane foaming

5). Vacuum tube: Al/N coating, 58X1800mm / 70 X2100mm

6). Logo: GOLD SOURCER, OEM

7). Capacity: 200L/240L/300L/360L

8). Tube quantity: 20-36 pcs

9). Heat preservation: 72hrs

10). Hail resistance: 25mm

FEATURES:
1. Copper coiler in tank bear pressure
2. New running water can be used directly as the water flows through copper coiler and
absorb the heat, and then be warmed.
3. Storage tank is used to heat copper coiler; the cooper coiler is the heat exchanger.
4. There is a sub-tank on storage tank, which can supply water to storage tank
automatically
5.The preheated type solar water heater is normally equipped with a electrical heating
system
