2,000-watt Electric Heater | 7 Answers You Should Know

A 2,000-watt electric heater is a good heating option to keep a medium-sized room of about 300 sq. ft warm during the winter.

There are some important considerations to help you use to install the heater properly, use it heater safely, and get a good idea of the indicative running costs of the heater.

So, in this post, I have compiled:

  • 7 key answers to commonly asked questions about suitable space for the 2,000-watt heater, cabling information,
  • how to maintain it,

and indicative costs of running the heater to help you decide the 2,000-watt heater is the right fit for your heating needs.

#1. What Size of Breaker for a 2,000-Watt Heater?

A 2,000-watt, 240V electric heater should be connected to a 15 amp double pole circuit breaker.

According to the NEC 2017 guidelines, the over-current protection device’s rating should be 125% of the continuous appliance’s current rating.

The continuous current rating for a 2,000-watt, 240-watt heater is 2000/240=8.3A.

8.3A x 125% =10.4A, approximately 11A. The next standard circuit breaker size is 15 amps.

The heater should be connected to a dedicated circuit to avoid tripping the circuit breaker likely when the combined current draw from additional appliances exceeds the 15A rating of the circuit breaker.

#2. What Wire gauge for 2,000 watt heater?

You can use 14 AWG cable for the 2,000-watt heater or a smaller gauge (even higher current rating). 14-gauge is rated 15A and matches the recommended 15A circuit breaker rating.

If the heater needs two conductors and the ground wire, 14/2 wire works fine.

Selecting a suitably sized cable prevents the danger of cable failure from overheating when the conductors and insulation are exposed to higher than recommended temperatures.

#3. How many amps Does a 2,000-Watt Electric Heater Draw?

A 2,000-watt heater draws about 8.3 amps at 240V when operating at full power.

Some heaters may have a single power output setting while others may have the option to select lower power modes.

Therefore, check which power mode options your electric heater has.

A heater with both high and low power settings draws the maximum current of 8.3 amps when set to the high power setting and a lower current that corresponds to the power output at the low setting.

While a single power output heater draws the maximum current all the time when the thermostat is on and zero when it is switched off by the thermostat.

#4. How many square feet a 2,000 watt Heater is heat?

2,000-watt heaters are generally suited to heating spaces of about 200 – 300 sq. ft, depending on the heater design – fan or no fan option, radiator type, or single electric element type.

Therefore always consult the user manual for your specific heater model for guidance.

In addition, there are other factors that affect how large a room the heater can ably heat such as how well insulated it is, the number of windows, and the ambient temperature.

In general, insulated spaces, spaces with few windows, and locations with warmer climates need less heating.

#5. How Much Electricity (kWh) Does a 2,000 watt Heater Use?

The 2,000-watt heater consumes roughly 2,000 watts of electricity.

The estimated annual consumption for this heater works out to about 7,300 kWh – assumes about 10 hours of operation per day.

Note: These kWh are indicative, the actual estimated annual energy consumption varies according to the heater’s usage pattern.

Your heater’s annual consumption may differ depending:

  • on the mode you set – high power, maximum energy consumption versus a low power-economic mode.
  • how high or low the temperature the heater should heat the room to. Selecting higher temperatures increases the energy consumption.
  • How well insulated the space to heat is. Opening the door to a room the heater is supposed to heat increases your energy consumption.

and finally, the prevailing climate of the area – overall consumption will be lower in warmer winters as an example.

What Is the Cost per Hour of Running a 2,000-Watt Heater?

Assuming an estimated daily energy consumption of 20kWh and an electricity tariff of $0.133, a 2,000-watt heater will cost approximately ¢ 0.11.

This is based on about 10 hours of operation per day. Note: The running costs are indicative, the actual running cost varies according to the heater’s usage pattern and local tariff.

This is calculated using the formula, the heater’s estimated hourly energy consumption (kWh) x the electricity tariffs for your location.

What Is the monthly cost of Running a 2,000-Watt Heater?

Assuming an estimated monthly energy consumption of 600kWh and an electricity tariff of $0.133, a 2,000-watt heater will cost approximately USD 79.8.

This is based on about 10 hours of operation per day. Note: The running costs are indicative, the actual running cost varies according to the heater’s usage pattern and local tariff.

This is calculated using the formula, the heater’s estimated hourly energy consumption (kWh) x the electricity tariffs for your location.

How much does it cost to run a 2,000-watt heater for 24 hours?

Assuming an estimated daily energy consumption of 20kWh and an electricity tariff of $0.133, a 2,000-watt heater will cost approximately USD 2.7.

This is based on about 10 hours of operation per day. Note: The running costs are indicative, the actual running cost varies according to the heater’s usage pattern and local tariff.

This is calculated using the formula, the heater’s estimated hourly energy consumption (kWh) x the electricity tariffs for your location.

#6. How many BTU is a 2,000-watt heater?

A 2,000-watt heater has an estimated BTU/hr of 6,820.

This can be calculated using the ratio, 1 W = 3.41 BTU/hr. 2,000 watts is 2,000 x 3.41 = 6,820 BTU/hr.

#7. How to Maintain the Electric Heater Safely?

Periodically maintaining the electric heater helps ensure that is continues to work well and efficiently too. The basic maintenance required involves wiping off the dust from the heater body and vents periodically.

To maintain the heater safely:

  1. Always switch off the electric heater first and allow it to cool.
  2. Next, proceed to wipe with a damp cloth any dust build up on the vents and wipe the vents dry. You may need a vacuum cleaner to remove the dust behind the vents.
  3. Reconnect the heater to the electricity supply after it has dried properly to prevent electric shocks!

Summary

A 2,000-watt heater rated 240V draws a maximum current of 8.3 amps when running.

This heater may have a single power output or have more operating modes with lower power consumption depending on the desired level of heating and energy-saving goals desired.

The 2,000-watt heater has a BTU/hr of about 6,820.

To operate safely and reliably, the 2,000-watt heater should be connected to a 14 AWG cable and protected with a 15A circuit breaker.
