The solar water heater will absorb energy from the sun and rapidly use it to heat water.

This easy to use set includes a solar water heater and digital thermometer in a plastic case. It can be used outdoors in the sun or indoors with a desk lamp. This set can be used as it is or you can add a data logger and Temperature sensor to monitor how long it takes for the water to get hot, and what happens when it’s cloudy. A Light level sensor will record changes in sun conditions so this can be compared with the rise in temperature.
