Solar Water Heater Model
Product Code : SCL-PLE-11697
Quick Answer: The Solar Water Heater Model shows how sunlight heats water using a matte-black fluted collector under a transparent cover, linked by pipes to an elevated insulated tank so water circulates on its own by thermosyphon.
Last updated: 18 October 2026
Key Features
- Matte-black fluted absorber plate collects solar radiation.
- Transparent cover traps heat by the greenhouse effect.
- Elevated insulated storage tank with inlet and outlet ports.
- Thermally conductive pipes join the collector to the tank in a closed loop.
- Frame tilts to face the collector towards the sun.
Technical Specifications
| Specification | Value |
|---|---|
| Collector | Matte-black fluted absorber plate |
| Cover | High-transmittance transparent glazing |
| Storage tank | Insulated, elevated, inlet and outlet ports |
| Pipework | Thermally conductive tubing, closed loop |
| Frame | Adjustable tilt angle |
| Circulation | Natural convection (thermosyphon) |
How It Is Used
The model is set in sunlight with the collector tilted towards the sun. Water in the collector warms, becomes less dense and rises to the tank, while cooler water flows down to replace it. Students measure the tank temperature over time to see solar energy being stored as heat without any pump.
Frequently Asked Questions
Does the Solar Water Heater Model need a pump?
No. Water circulates between collector and tank by natural convection, the thermosyphon effect.
Can the collector angle be changed on the Solar Water Heater Model?
Yes. The frame has an adjustable tilt angle so the collector can be aimed at the sun.
