I want to install electric
radiant heat warm floors in my bathroom. The manufacture recommends a
dedicated circuit. To save
money I would prefer not to install a dedicated circuit. My workaround is to use a switch that would
only allow either the warm floor to be selected or the Jacuzzi tub (3/4 HP
motor already installed on a dedicated circuit). The amp draw of the floor is 2.5 amps and the
motor, if I have my facts correct draws 14 amps. The other option is to tap off of our bedroom
lights and outlets which are on a 20 amp circuit for the warm floor. The outlets in the bathroom are on their own
circuit. I was going to use a single
pole double throw center off switch but when working out an install diagram I
realized the control unit for the floor would be un powered when the Jacuzzi was
selected and it would lose the day date after being un powered for 30 min. The
only switch I found that could work is DPDT 20 Amp switch. I was planning on hooking it up as I have
diagrammed. My question is will this work
or is there a better solution?
