Active solar water heater
“How can we create another iteration of an active solar water heater?”
Batch-collector solar water heaters are one way of heating water using solar power, but as engineers, we are never satisfied with just one way of doing things! So, how can we innovate on this design to create a new system? Well, let’s think about it. We know that using a cylinder to store heated water is a well thought out design choice. But how about we were to modify how it is heated up? Instead of just having a passive system where the cylinder is warmed by the sun, let’s instead extract it using a solar powered pump, push it through a solar panel, and let it come out back into an isolated part of the cylinder as heated water, which has a pump to escort it to the user’s house. These pumps will come equipped with two ball valves to stop the pumps in case the solar panel is no longer in use.
