Feature:

The pressure solar collector can bear 0.3Mpa pressure of the water. It can still work well in case some tubes are broken.

The cost is higher than non pressure solar collector,because it has the stainless pipes inside vacuum tubes ,most suppliers use copper inside ,but we compare cost and effciency ,we find stainless steel id cheaper than copper ,but efficiency is similar.

It is not heat pipe or U-pipe,it is direct flow system ,just add a stainless steel pipe,water heated by tubes ,goes up directly into manifold,no anti-freeze liquid or others ,just water.

You can connect this type to your electrical boiler or gas heater or other pressure heater directly ,It also can be used as a part of split system.

Principal: Evacuated tubes convert solar energy into thermal energy that is transferred to stainless steel tubes by an aluminum fin with high solar energy absorption and low radiance loss.

Warranty: 1~2 years for whole system
