Flat Plate Solar Water Heating System - Features  
 
• Product looks stylish and of high quality – it is a completely sealed unit.  
• Unique vent system on each corner—the biggest problem with water and solar is condensation, panels are slower in the morning when full of condensation—the sun will dry this up but it means it takes longer for the  
system to get to 100% efficiency. MPS systems uniquely have a air flow running diagonally from top to bottom that keeps them free from condensation.  
• There is a knockout on the base of the unit so any water inside can escape -meaning the heating insulation will not rot or smell.  
• The frame is bent out of one continuous piece of aluminum which makes it 5 times stronger for high wind forces. The absorber is held in place by springs at each corner so in shipping or installation it will not move more than it is supposed to.  
• Thermal bridge - copper and aluminum expand at different rates—our collectors design takes this in to account so there is less risk of buckling or cracks in the tubes.
