wiring radiant floor
Just installed 120v radiant heat pads under wood floor, ran the wires and sensor wire up the wall to an existing thermostat control box. The existing control box controlled a 240v radiant ceiling which we deleted to install recess lighting. The problem I am facing is the power feed I wanted to use is 240v but the new thermostat and radiant floor require 120v. How do I go about change the 240v feed to 120v, it would be nice to run new romax but it would be fine to also use the existing wires and delete the double pole breaker.
Another idea I have is, directly under the thermostat location is a 120v outlet, can I tap into the outlet to get the power or is that a no no. The thermostat has a built-in gfci
It would of be nice to know it was 240v before I place the order for the radiant floor, could order 240v pads. To late now floor is down and it is not coming up.
