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)
To meet Energy Star minimum standards, a bathroom fan must have an efficacy level of at least 1.4 for small fans (up to 89 cfm) and a level of at least 2.8 for larger fans (90 to 500 cfm). Highly efficient fans can have efficacy levels upwards of 13.ans and Features. Basic fan-only ventilation units can use as little as about 6 watts, for highly efficient models, while many standard units often use around 60 watts or more. In general, electricity usage is related to airflow, measured in cubic feet per minute (cfm) and the fan's energy-efficiency.
