Do Floor Radiant Heating Pads Require Dedicated Circuit

With a 4 5 amp draw by the floor why can t we use the existing 20 amp circuit that is shared by the bathroom outlets.

Do floor radiant heating pads require dedicated circuit.

The heating wire that would go in is rated at only 300 watts. Under floor heating is much different than electric strip coil heaters. Is there really a danger in hooking this up to my bathroom bedroom circuit. The electrician also can install the control panel heating sensor in the wall.

Per the electrician quotes this is a huge p i t a. I want to put in under the tile floor heating in my bathroom which is being renovated. What i would do is figure out the square footage of radiant heat it doesn t have to go next to the walls and calculate the wattage. The current requirements of radiant floor heating systems usually require a dedicated system.

However small circuits under 20 sqft can be made with just 2 amp current maximum meaning they can be installed on the existing circuit. The instructions that come with the heating cable say that the circuit for the heating wire must be separate. This is impossible to do. If you re installing radiant floor heat in an existing room you ll need a dedicated 15 to 20 amp gfci protected circuit to power the system and an excuse to lay a new tile floor.

Some of the under floor radiant heat systems don t require a dedicated circuit. If you re remodeling it s a good time to satisfy both requirements. A bathroom size warm floor retrofit will cost 400 to 700 including the cost of the new tile.
