# Quick Answer: How many kw does an electric furnace use?

Contents

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.

## How many watts does the average furnace use?

Most gas heat furnaces use less than 600 watts of electricity, or less than half of a typical 15 amp electric circuit.

## Is electric furnace expensive to run?

While the up-front costs might be tempting, electric furnaces cost more to operate monthly. Electricity is more expensive per unit than natural gas, making the lifetime cost higher than gas heating. Electric heating takes more time. The heat from your furnace won’t reach the high temperatures of a gas furnace.

## What size generator is needed to run an electric furnace?

An electric furnace requires a generator to produce at least 10,000 watts if it’s going to keep your home warm.

## What size electric furnace do I need for a 2000 square foot home?

1,500 sq ft 14 – 16 kW 16 – 18 kW
1,600 sq ft 15 – 17 kW 17 – 19 kW
1,800 sq ft 16 – 19 kW 19 – 22 kW
2,000 sq ft 18 – 21 kW 21 – 24 kW

## How many kWh does it take to heat a house?

The average home requires around 12,000 kilowatt hours (Kwh) of heat per year. Therefore, in order to achieve this, a heat pump with a CoP of three would use 4,000 kWh of electricity annually. This figure will depend on the size of your home, how well insulated it is and how much hot water you use.

## How many amps does a electric furnace use?

The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities; however, typically electric furnaces require a draw between 60 and 80 amps.

## How many kW of electric heat do you need per square foot?

Plenum heaters can be sized using 8 to 10 watts per square foot with 8 foot ceilings. Use 15 kW models in structures 1500-2000 square feet. Use 20 kW models in structures 2000-2500 square feet.

## Are new electric furnaces more efficient?

More efficient, but costs more to run

While electric furnaces are far more efficient at converting their energy source (electricity) into heat than other types of furnaces, this efficiency is counterbalanced by the market prices of each energy source.

## How efficient is an electric furnace?

The efficiency range of an electric furnace is very simple; all modern electric furnaces have an AFUE of 100%. That means that all electric furnaces convert electricity into heat energy without any wastage.

## How many kWh does an electric furnace use per month?

A month has 24 x 30 = 720 hrs. A 20 kW furnace running steady would take 720 x 20 = 14,400 kWh.

## Can a 2000 watt generator run a furnace?

Will a 2000 watt generator run a heat pump or a furnace? In general, a 2000 running watts generator doesn’t provide enough power to run a heat pump or electric furnace.

## Will a 6000 watt generator run a furnace?

Stagger Startup. Medium-sized generators will power enough appliances for survival: refrigerator, freezer, furnace fan and lights.

## How many amps does a 20 KW furnace use?

20 kw Heat Strip drawing 30 amps for each 5kw.
