Westech Evacuated Tube Solar Collectors Operation

Step 1:  The absorber coating on the inner glass tube absorbs sunlight and converts it into heat.
Step 2:  Steam forms inside heat pipe which transfers heat rapidly up to the manifold.
Step 3:  A pump circulates water or heat transfer fluid through the header pipe, carrying heat back to the storage tank.  Gradually throughout the day the tank is heated up.
The tank can be boosted by an electric element, gas/oil boiler, or the solar tank can simply feed an existing water heater tank with solar pre-heated water. 

 
 


Westech Collector Mounting

Westech  WT solar collectors can be mounted on a roof, wall or even on the ground. The key is ensuring optimum exposure to the sun through the day.

Design Advantages

Evacuated Tube Efficiency,The vacuum space in the evacuated tube greatly reduces heat loss. This greatly increases the conversion efficiency at higher water temperatures or when the outside temperature is very cold. For a thorough understanding of evacuated tubes
