Electrical Consumption for SunRay Barrett Sauna - 20 minutes

Assuming the 1290 watts refers to the wattage of an infrared sauna, the electrical consumption in kilowatts can be calculated as follows:

kilowatts = (wattage * time) / (1000 * voltage)

If the sauna is used for 20 minutes and operates on a standard US voltage of 110V, the electrical consumption would be:

kilowatts = (1290 * 20) / (1000 * 110) = 0.24 kW

Therefore, the electrical consumption of a 1290 watt infrared sauna operating at 110V for 20 minutes is approximately 0.24 kilowatts.
