Electric Furnace Amp Draw

Electric furnaces are rated in kilowatts.

Electric furnace amp draw.

Electric furnaces range from 10 kilowatts to 50 kilowatts we estimate that a 2 400 square foot home using a modern high efficiency electric furnace uses 18 000 watts for heating when the furnace is being used. The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities. Furnace fans account for 80 percent of the electricity used by furnaces so total furnace electricity use averages about 625 kwh per year. However typically electric furnaces require a draw between 60 and 80 amps.

By multiplying the volts by amps you will receive total wattage. A 10 kw furnace draws 10000 watts. A gas fired forced air home furnace typically requires a small amount of electricity to ignite and operate in your home. The following formula will let you figure it out.

Most furnace fans draw between 500 and 800 watts with an annual electricity use that averages about 500 kwh per year. Most gas heat furnaces use less than 600 watts of electricity or less than half of a typical 15 amp electric circuit. It is a good idea to have solar or generator power to supplement the charging of your batteries when not connected to shore power. The typical furnace will draw about 8 amps of power.

In colder climates heating is required 6 to 8 months of the year with a furnace running 4 hours a day during the colder months. The 12 volt battery system in your rv runs many of your electronics on your camper rv or travel trailer. 10000 240 41 6 amps.
