I found another website describing the heat output of cable heat electric flooring with a 3" standard spacing to be 34 BTU'S per square foot.

Rather than trusting this site the cable heat kit I'm going to use is from Warm Tiles (240 Volt DFT 2065 60-70 sq feet 3.3 Amps).

Can you covert Amps to Btu's per hour? Just found this thread here.

With this math I get 3.3 Amps X 240 Volts = 792 Watts

792 Watts x 1 hour = 792 Watthour

792 Watthour x 3.41214148 = 2702 BTU

With the rate of 34 BTU's per square foot I get 2210 BTU's

Which one is right? Is it possible the 19 % drop is allowed for the heat loss through the setting material and tile?

Thanks,

"Btu is a unit of energy not power, not sure why you would need Btu values. Usually things like backup power supplies are rated in Watts or kilowatts.

But here is how you would do it.

Amps * Volts = Watts

Watts * hours = watthours

watthours * 3.41214148 = Btu

So you would need to know amps, volts (usually 120 or 240), and the number of hours.""Btu is a unit of energy not power, not sure why you would need Btu values. Usually things like backup power supplies are rated in Watts or kilowatts.
