The heat collectors and the water tanks are connected perfectly, the heat which the panels collected will be stored in the water tank, it guarantees 24 hours per day to provide the hot water, and the system can work even under the -30 degrees. It can supply with a few tons even more water, is an ideal hot water supply system. It is applied to the big hotels, restaurants and other large places.
1: The water tank should be placed higher than the heat collectors, while the models are isolated types and the heat collectors are not pressure-enduring; The water recycled freely by the height difference between the water tank and the heat collectors.
2: The water tank should be placed lower than the heat collectors, while the models are isolated types and the heat collectors are pressure-enduring, the water is recycled by the water pump between the water tank and the heat collectors, the specific pressure-enduring models, please see the information of the pressure-enduring models on the web.

1. Blocking design, easy assembled
2. It can be mounted sloping roof and wall without frame
3. The pipeline is made of red copper and conducted by heat transfer medium liquid; water can't flow in the vacuum tubes and is operated when confined
The characteristic:
1 the vacuum tubes absorb the solar energy and transfer into the heat energy, then pass it to the u pipe, it can get high temperature.
2 there is no water in the vacuum tube, so the tube will not break in the winter.
3 it is steady and credible.
4 it can be combined with the architecture perfectly.
5 it can be combined with existing pipeline.
6 it can still operate in the event of occasional tube breakages.
The details of material:
Outer tank: alnico 1.5mm
Manifold: 22mm thickness 2mm
U copper type: 8mm thickness 0.6mm

Characteristic:
The heat pipe solar collector is connected with storage tank, electric control device, hot water mix unit and fittings for circulation and installation. The selective coating on the inner cover of the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes by aluminum fins. The liquid in the heat pipe changes into vapour which rises to the condenser. The heat then passes through the heat ex-changer and the vapor becomes liquid, returning to the base of the heat pipe. The heat conducts to the heat transfer liquid (anti-freezing liquid or water) via a copper pipe. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.
