How to figure out the Kilowatt Load usage for your WarmlyYours floor heating system?
On the new touchscreen thermostat UDG4-4999, during the startup menu, users will be prompted to enter their KW load usage. Floor Load is the total wattage of the floor heating system that can be found on the installation or electrical plan. A lot of our customers may not know this for a number of reasons (they did not install or order the floor, it may be a replacement, and info on the installation has been lost, etc.) Here is an easy way to help out and get the Kilowatt load they need for this menu step.
Kilowatt load usage can be figured by taking the square footage of the open floor space multiplied by 15 (for tile) or 12 (for carpet and laminate). This gives us the total wattage which we then divide by 1000 to get the Kilowatts.
An example: the user has a 100-square-foot room that is tiled. The math would look like this: 100 sq feet X 15 watts per square foot = 1500 divided by 1000 = 1.5 KW
