One of the biggest drawback with existing evacuated tubes usedin solar water heating is that they produce very high temperatures if fluid is not flowing. The Engineers at WSE have solved this problem and even in stagnation situation the temperature will not rise to cause glycol failure.

CSA 378 and SRCC Certified

Low Cost

Up to 50% solar thermal output even on cloudy days

25 year warranty on tubes

Tubes are vacuum formed, so wind and cold Canadian temperatures have minimal effect on the efficiency of the evacuated collector. Great on those 40 below sunny days.

Sophisticated but simple design with no moving parts (100% glass) allows for up to 40 years of trouble free operation

Due to the cylindrical shape of the evacuated tube, the sun is perpendicular to the surface of the glass all day.

10% higher efficiency than standard evacuated tubes

Design so no liquid spillage even if super heat tube is damaged

Light Weight so easy to install with low roof load

The 3 inch gap between tubes results in low wind re-sistance making installation a much easier task
