These 3 heaters would require 12/2 wire and a 20 Amp 2-Pole breaker if they were to all be placed on the same circuit. If more heaters are needed either run a new circuit or increase the wire and breaker size to accommodate the load.)5.hese 3 heaters would require 12/2 wire and a 20 Amp 2-Pole breaker if they were to all be placed on the same circuit.

Ceiling fans help cool a room by moving air which causes evaporative cooling. Fans range in size from 36 inches to 56 inches using 55 to 100 watts, a typical 48 inch ceiling fan will use 75 watts. Click calculate to find the energy consumption of a 48 inch ceiling fan using 75 Watts for 3 hours a day @ $0.10 per kWh. Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5)
How much energy fans use depends on the size of the motor, pitch of the blades and what speed is selected. Savegreenly recently tested the power use of fans, air purifiers and humidifiers and found a big difference in how many watts they each drew.Testing A Box Fan's Energy Use. The first fan we tested, shown above, was a common box fan which sells at discount stores for around $30.This model is made by Galaxy.avegreenly recently tested the power use of fans, air purifiers and humidifiers and found a big difference in how many watts they each drew.
