On Solar Tube Performance
Heats 5 gallons of water from 68°F (room temp) to 122°F (above hot tub temp) in four hours if recirculated by a pump.
Jumps temp of any input water circulating through by 37°F at flow rate of 5 gallons per hour (pump required).
Heats water at a rate of 165 watts. Twice the energy collection rate of solar panels!
20 1/2″ long (500mm) X 2 1/4″ outside diameter (58mm) X 1 3/4″ inside diameter (43mm)
Box of Ten (10) Solar Vacuum (evacuated) tubes only.
Do not exceed 100 psi (Ok for most city supply pressure). Closed systems must have relief valve.
HIGHLY EFFICIENT SOLAR THERMAL COLLECTOR. Sunlight is extremely powerful. Steam & burn danger without proper handling. Remember to never connect to a closed system without pressure relief. Do not touch internal components while heated.
