How much electricity does a 750-watt space heater use?

Electric heaters use, in general, a considerable amount of electricity compared to other electronic appliances. So how much electricity do electric space heaters use per month?

Though the 750-watt heater is one of the smaller heaters on the market, it consumes as much electricity as a 15 x 42″ LED TV at maximum power! That being said, electricity costs broken down per hour aren’t eye-popping numbers!

To give you an idea of how much it costs to run the heater per hour, it is only around USD 0.09!

From (750 watts x 1 hour) /1000 x USD 0.13. Assuming maximum power for 8 hours a day at 13 cents per kWh.

How much electricity (kWh) does the heater use?

A 750-watt heater consumes an estimated 6,000 watthours or 6 kWh over an 8-hour period assuming it runs at maximum power (thermostat set too high).

Over 30 days, its monthly energy consumption is about 180 kWh. Ultimately its electricity consumption depends on:

  • How many hours it runs
  • Its thermostat setting, i.e. whether it is set to run at maximum or low temperature

How much does it cost to run a 750-watt heater?

The cost of electricity depends on the temperature setting and the duration over which the heater is switched on.

The cost of running a 750 watts heater per hour

The cost of running the heater per hour is only USD $0.09 from (750 watts x 1 hour) /1000 x USD 0.09. Assuming maximum power for 8 hours a day at 9 cents per kWh.

The cost of running a 750 watts heater for 8 hours

Assuming the heater is used for 8 hours per day when set to maximum temperature with an energy cost of 9 cents per kWh.

The daily cost of running the heater is only USD 0.72 from (750 watts x 8 hours) /1000 x USD 0.09. Assuming maximum power for 8 hours a day at 9 cents per kWh.

The cost of running the heater per month

The monthly cost of operating the heater is USD 22.32 from (750 watts x 8 hours x 30 days) /1000 x USD 0.09. Assuming maximum power for 8 hours a day at 9 cents per kWh.

Tips to reduce the energy costs of running a 750-watt space heater

Since space heaters use so much electricity, you may want to limit the electricity consumption of the 750-watt space heater by using a number of strategies. Below you’ll find a few suggestions for reducing the average cost and overall running cost of your heater.

Adjust the thermostat to a lower setting when possible

The heater may have a low, mid, to max power setting. Using a mid-power setting could reduce its power consumption by as much as 50%. Do this when the room is already sufficiently heated or when you’ll be doing an activity that requires you to move around a lot.

Only turn on space heaters when you’re planning to use the room

Don’t leave the space heater running in a room you don’t even plan to use on a given day. Make sure it’s a secondary tool that you utilize only when necessary. Running your space heater all day in an empty room will run up your bill with unnecessary charges.

Unplug the electric space heater when it’s not in use

Unplugging your heater when it’s not in use can save you a few cents on your electricity bill. Devices still draw small amounts of power when they’re plugged in, even if you aren’t using them. Make sure to unplug your space heater if you don’t plan to use it for a time.

Improve its heating efficiency

Clean the heater regularly to remove any dust that may have built up on the heater, which reduces how much energy it is able to radiate. You can vacuum the heater or blow off the dust using compressed air or a blower.

How many amps does the heater draw?

The space heater draws an estimated 6 amps of current at 110/120V when set to maximum heat and about 3 amps at an eco or mid-level setting (if it has one).

The heater can be plugged into a regular 13 or 15-amp outlet, wired with at least 14 AWG wire that’s connected to a shared or dedicated 15 or 20-amp breaker as long as the maximum current rating of the breaker and wiring is not exceeded.

Should the circuit breaker trip, consider running the heater in eco mode or running the heater alone on the electrical circuit.

The power consumption of a 750-watt space heater uses?

A 750-watt space heater uses an estimated 750 watts of power when set to the maximum or high setting and about 375 watts when set to the low or eco setting ( for the models that have the feature).

Should you plug the space heater into an extension cord?

While you may be able to plug the space heater into an extension cord, many manufacturers recommend that it be plugged directly into a 110V outlet or receptacle.

Many extension cords are low quality, overrated, prone to overheating, and can melt or catch fire when the current draw exceeds the current handling capacity of the extension cord.

Only plug the heater into an extension cord if you are sure that it is able to supply the rated current draw of the heater.

Average cost and running cost of a 750-watt space heater

A 750-watt heater can use as much as USD 22.32 over the period of a month if used continuously at maximum power.

You can plug The heater into a regular 13 or 15-amp outlet or connect the heater to a shared or dedicated 15 or 20-circuit. Avoid using an extension cord, and instead, plug it directly into a wall outlet.

How much does it cost to run a 1,500 watt heater for 8 hours?

A 1,500-watt heater will simply cost approximately double the cost of a 750-watt space heater. This means if run on high for 8 hours, the cost will be about $1.44.

How much does it cost to run a 1,500-watt heater for 30 days

A 1,500-watt heater will cost about $44.64 if run for 8 hours per day for a month straight.

How much electricity does a space heater use per hour

The amount of electricity a space heater uses per hour depends on it’s wattage, the setting it’s run on, and what type of heater you buy.
