I have a bathroom in my shop building that I use infrequently. I do not want to maintain hot water 24/7 there. I want to use a Bosch 2.5 gallon instant hot water device connected to a cold water line. I would like the outlet to become activated when it detects motion in the bathroom and stay on for 5 minutes or so, or until there is no motion after that time.
The main reason I want to do this is that if I have a switch or plug-in/unplug the heater when needed that I will forget to turn it off or unplug it when I am through.
I see most motion detectors can only control low amperage devices. This water heater is 1,400 watts. Is there such a thing as a motion-controlled outlet that can handle this load?
If not, I suppose I could rig a relay to be activated by the motion sensor to energize the outlet, but I would like to make it more simple.
Another option would be to use a rotary timer like on a hot tub. Are those direct connect to an outlet or do they need a relay involved?
This is the heater I am looking at: https://www.amazon.com/Bosch-Tronic-2-5-Gallon-Electric-Mini-Tank/dp/B0148O658Y/ref=pd_ybh_a_5?_encoding=UTF8&psc=1&refRID=SPZ8JFCMYAS3QM1A36WB
It is 110v and has an adjustable thermostat.
