WSE is committed to developing the best solar water heating system for North America.

Our new WSE58 Super Tube system gives you the most efficient panels on the market today at the best payback.

The WSE58ST is so simple in design that you can expect trouble free operation for over 40 years with 50% thermal output even on cloudy days.

We are so confident in this product we will do a free design and financial analysis for your solar project which we insist you take to the competition for comparison.

WSE58 Super Evacuated Tube Features and Benefits

• One of the biggest drawback with existing evacuated tubes 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.

• 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 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

Solar Thermal Output of One WSE58ST in Saskatoon

If heating with electricty will save you about $420 a year next year per WSE58ST panel

One panel will save you about $100,000 over the next 35 years based on a 6% yearly energy increase

Test Report for WSE58x1800mm 15tubes
Test condition: Bright sun all day and water flow rate of 3.16L/min, No Wind,Facing due south at an angle of 60 degrees above horizontal , The flow rate through a positive displacement pump was measured using flow and time. The temperature was measured using thermistors.
Test Place: Saskatoon

We observed up to 200 btu/hr per tube in sunshine, but the real advantage over other evacuated tube designs is the up to 100 btu/hr per tube thermal output on cloudy days.

Our standard 20 tube could see up to 4,000 but per hour, we use 3,500 btu/hr to allow for radiation variations.

Absorption reaching 94%

Dimensions of 20 tube system 80 inches by 72 inches
