How do i calculate how many watts does a dehumidifier use?

Answer 1

The EnergyStar site, reliable on these matters, points to an interactive calculator on myenergystar site. This estimates the real power consumption based on room size and its humidity (you must give a subjective evaluation). Another choice in the form, for determining power consumption, is to measure how much water is condensed inside every day. This works if you already have the dehumidifier running, The interactive dehumidifier power calculator is at http://www.myenergystar.com/ProductsAndDiscounts.aspx?type=dehumidifier&menu=calculator Guido (tguido56)

Answer 2

There are a few variables here. What the dehumidifier is used for room or whole house, relative humidity where you live and what the setting of the dehumidifier operates at. Look for the nameplate on the humidifier. There it should tell you the wattage that it operates at. If not use the equation Watts = Amps times Volts. Kilowatts per hour is what your utility meter reads and that is what you get billed for. The more the unit operates the higher the cost is to you.

Answer 3

To calculate the watts used by a dehumidifier, you need to know the voltage and amperage of the unit. The formula to calculate watts is watts = voltage x amperage. Simply multiply the voltage (usually 120V in the US) by the amperage (found on the dehumidifier's label or specifications) to determine the watts used.

Answer 4

Divide the wattage by the voltage - this equals amps.

Answer 5

Look on the nomenclatre to find your volts and amperes. Multiply them to get your watts.
