# Electric Baseboard Heater Power Consumption Calculator Share the article

If you are planning to buy a new electric baseboard heater or wondering how much electricity your existing electric baseboard heater is consuming then this article is for you. In this article, we will calculate the power consumption of an electric baseboard heater and also look at how much it costs to use one.

Electric baseboard heaters are normally rated between 250 watts to 3000 watts. A 1500 watt electric baseboard heater running for 4 hours every day will consume around 6 kWh of electricity in a day, and 180 kWh of electricity in a month.

This would roughly translate to a monthly electricity cost of \$ 29.16 in the US, £ 64.80 in the UK, and C\$ 28 in Canada.

## Electric Baseboard Heater Power Consumption:

The power consumption of an electric baseboard heater (for that matter any electrical appliance) depends upon two main things,

1. First is the wattage of your electric baseboard heater,
2. And second is the electricity tariff in your area.

Before we jump into calculating the power consumption of your electric baseboard heater let’s see what these terms are and how you can find out your electric baseboard heater’s wattage and the electricity tariff of your locality.

If you already know these terms and just want to use the calculator then please scroll down to see the calculated results or use the calculator yourself.

### What is the Wattage of an Electric Baseboard Heater:

Generally, electric baseboard heaters are rated between 250 watts to 3000 watts.

You can find the wattage of your electric baseboard heater by reading the label on it or just look for your baseboard heater on amazon and you will find its wattage in the description section.

Also, as a general thumb of rule, for every foot (1 ft = 12 inches) increase in length the wattage increases by 250 watts. Hence, an 8 ft (96 inches) baseboard will be rated at approximately 2000 watts.

(If you don’t have time to do this, then don’t worry I have put together a table at the end that shows the power consumption of a range of electric baseboard heaters with different wattages.)

If you don’t know what a watt is then here is a quick explanation,

Watt is the unit of power. It means the rate at which electricity is consumed or produced by a device. For example, a 50-watt TV consumes power at a rate of 50 watts per hour, it does not mean that the TV consumed 50 units of electricity, it means it will consume power at a rate of 50 watts every hour.

So in short, the wattage of a baseboard heater lies between 250 watts to 3000 watts and you can find it by looking at the label on it. With that out of the way, let’s look at what is electricity tariff.

In simple words, electricity tariff is the amount your electricity provider charges you for one unit (kWh) of electricity. I live in Mumbai, India here the electricity tariff is Rs 12/kWh.

(What is a Kilowatt hour (kWh) Kilowatt hours or units of electricity is the energy consumption of a device. For example, a 50-watt table fan running for 50 hours will consume 50 watts x 50 hours = 2500-watt hours = 2.5-kilowatt hours of electricity = 2.5 units of electricity. (1 kWh of electricity = 1 unit of electricity))

To find your electricity tariff, just look into your previous month’s electricity bill and find out your monthly electricity consumption, then just divide your monthly electricity consumption by your total monthly electricity bill, the figure you get is approximately your electricity tariff.

I have put together the following table that shows the electricity tariff of a few countries.

## Electricity Tariff Around The World:

## Calculate Electric Baseboard Heater Power Consumption:

With these two pieces of information in hand, you are ready to find the power consumption of your electric baseboard heater.

Let me show you an example,

I have selected a 72-inch, 1500 Watts electric baseboard heater listed on amazon.

(The 2-wattage you see is for the separate voltage setting, meaning, in 240 volts the baseboard heater will run at 1500 watts, and at 208 volts it will run at 1125 watts.)

Let’s assume we will use this 1500 watts electric baseboard heater for 4 hours every day for the entire month.

Hence, we will calculate the daily, monthly, and annual power consumption of this 1500 watts baseboard heater.

With the knowledge of your electric baseboard heater wattage and your electricity tariff, just use this simple formula to calculate power consumption.

Power consumption of an appliance = Wattage of the appliance X operational hours

Cost to run an appliance = Power consumption of the appliance X electricity tariff

(Operational hours is basically the number of hours you are using your electric baseboard heater)

Now let’s calculate,

### How Much Power Does A electric baseboard Consume:

In our case, wattage is 1500 watts and operational hours are 4 hours in a day, 120 hours in a month, and 1,460 hours in a year.

Hence by using the above formula.

• Daily power consumption of a 1500 watts electric baseboard heater (4 hours) = 1500 watts X 4 hours = 6 kWh
• Similarly, the Monthly power consumption of a 1500 watts electric baseboard heater (4 hours/day @ 30 days) = 1500 watts X 120 = 180 kWh
• And the annual power consumption of 1500 watts electric baseboard heater (4 hours/day @ 365 days) = 1500 watts X 1460 = 2,190 kWh

Now that we know the power consumption just multiply it by your electricity tariff and you will get how much it will cost you to run your baseboard heater.

let’s calculate how much it will cost to run this 1500 watts electric baseboard heater for 4 hours every day for an entire month in USA, UK, and Canada.

• In the US, the avg. electricity tariff is around 16.20 cents per kWh, hence it will cost around \$ 29.16 (180 kWh X 16.20 cents) to run this 1500 watts electric baseboard heater for 4 hours every day for an entire month in the US.
• In the UK, the avg. electricity tariff is around 36 pence per kWh, hence it will cost around £ 64.80 (180 kWh X 36p/kWh) to run this 1500 watts electric baseboard heater for 4 hours every day for an entire month in the UK.
• In Canada, the avg. electricity tariff is around C\$ 0.156 per kWh, hence it will cost around C\$ 28.08 (180 kWh X C\$ 0.156/kWh) to run this 1500 watts electric baseboard heater for 4 hours every day for an entire month in Canada.

### How Much Does it Cost To Run An Electric Baseboard Heater:

For your reference, I have calculated the cost to run this 1500 watts electric baseboard heater for 4 hours daily throughout the entire month in the US, the UK, and Canada.

If your country is not on the table, then just note down the power consumption and multiply your electricity tariff to get the running cost.

The above figures show the maximum power consumption of a 1500 watts electric baseboard heater, however, the actual power consumption can be 10 % – 20 % on the lower side depending on the operating settings and environment.

(I am trying to get my hands on one of these heaters to measure its real-time power consumption using my power consumption meter, I will update the post once I do it.)

Also, most of us use heaters only during winter which lasts for 2-3 months in most places. Hence, your annual power consumption will be much less.

### Electricity consumption Of different Wattage Electric Baseboard Heaters:

For your reference, I have made the below table that shows the power consumption of a range of electric baseboard heaters of different wattages. I have assumed 4 hours of daily operation for an entire month.

As I said before, you can use the power consumption values from the above table and multiply them by your local electricity tariff to get the running cost.

Now go ahead and use the below calculator to find out the power consumption of your electric baseboard heater.

Just type the wattage of your electric baseboard heater, hours of usage, and your electricity tariff, and let the calculator do the math for you.

### Electric Baseboard Heater power consumption calculator:

If you are not happy with the approximate results and you want to know the exact power consumption, then I would suggest you buy a cheap Kill-A-Watt Meter from amazon.

### Calculate the exact power consumption of any Heater using Kill A Watt Meter:

Kill A Watt Meter is a simple device that gives real-time data on the power consumption of any device.

You can check it on amazon using this link – Kill A Watt Electricity Usage Monitor

To use a kill-a-watt meter to calculate the power consumption of your electric baseboard heater, first, connect your baseboard heater plug into the kill-a-watt meter and then plug the kill-a-watt meter in your wall socket and you are good to go.

Then start using your electric baseboard heater and you can see in real-time how many kWh (units) of electricity it is consuming.
