About This Product
The collector is tilted to face the light, filled through the funnel and set in sunshine or under a halogen lamp indoors, with one thermometer at the collector inlet and one in the tank. Readings every 5 minutes show warm water rising into the tank on its own, so students can see thermosiphon flow and calculate the heat taken up by the water.
Frequently Asked Questions
Does the Solar Water Heater Model STEM Lab need a pump?
No. Heated water becomes less dense and rises into the tank by thermosiphon action, drawing cooler water down into the collector.
Can it be used indoors?
Yes. It is meant for direct sunlight outdoors but can also be run under a high-intensity halogen lamp.
