Anyone ever heard of this. I got a guy who wants to finish his basement. He wants us to install baseboard heating and put the switch on a motion sensor so that the heat will kick on only when someone is down there. Strange but a unique idea I guess. Do they make a 220V Motion switch?
intersting concept. Doesn't sound that easy to me. Assuming you can find a 220v motion detector rated for the application. He would have to make periodic trips to the beer fridge to keep the heat going. hmmm. maybe not a bad idea when I think about it.

My local hardware store sells "stand alone" motion sensors, you wire them into your existing light. Stick one of those up in the corner of the room opposite the door, and wire it to a 120v coil of a contactor rated for the heaters. If you feed the heaters with 3 wire, then you can snitch the 120 off of one of the heater feeds. ( using the right size wire of course.) materials: motion sensor, contactor, box to hold it all, hand full of wire. TW Oh yea, the sensor will have to have its "dusk to dawn" feature disabled, but most have a setting or a "test" feature that will do that.

I would also incorpoarate a timed relay into the control circuit in conjunction with the motion sensor. That way When person enters the room heater comes on. Lets say man becomes immobile and motion sensor goes off. Timed relay would keep heater on for a preset length of time (10 min. for example) after man becomes immobile. This would avoid heater short cycling. and man stays warm. If man would come back to life before preset relay's time is up, motion sensor would kick in again, thus resetting the system and avoid interruption in heat.
