What are the Voltage and Amperage requirements for floor heating?
Both 110/120 & 220/240 systems are available. Mats are 12 watts per Sq Ft, which means you can control up to 137-150 Sq Ft of floor warming at 110/120v (and twice that for 220/240v) per circuit. Each circuit has a 15 amp maximum, and 1 thermostat control is required per 15 amp circuit. A dedicated circuit is recommended, but very small systems of 20 SF only require approx. 2 amps, so you may be able to add on to an existing circuit; a licensed electrician will know the answer for your project.
