innovations in water conservation, especially hot water which has a large amount of energy added to it, take many forms. Tankless water heaters eliminate the waste of having hot water constantly losing energy to the environment, and solar heaters cleverly pipe water to an energy collector in order to defray much of the energy required to heat water up to an acceptable temperature.
While both can reap real benefits, either one requires a significant cost and/or time commitment to set up. One less-involved alternative is the QiQi smart shower controller. Rather than helping to heat the water in a better or more efficient way, it addresses the issue of leaving the shower on too long to heat up.
Instead of turning it on and testing intermittently with your hand to see if it’s hot, you simply use a mobile app to turn it on. When the temperature is to your set point, it turns the shower off and alerts you via your phone that the shower is ready. Saving time and energy simultaneously—what’s not to like?
On the other hand, if you have enough time (and perhaps an understanding HOA) you can build your own solar heater yourself, as Jake Teater demonstrates in the video seen below:
