Electric baseboard heaters can provide an excellent way to keep you warm during those freezing cold months when you are longing for spring. They also offer many advantages to homeowners as well as investment property owners. However, be advised that along with the advantages that electric baseboard heaters provide there are also some disadvantages that you should be aware of as well. First, we’ll try to answer what are electric baseboard heaters and how do they work? Then we’ll see if we can answer the question, how much electricity does a baseboard heater use.
Electric baseboard heaters are one type of electric resistance heater that is installed on the wall along the floor. They have metal fins inside that heat the air as the air moves past the metal fins. As the cool air falls and goes through the metal fins, the cool air is heated and rises and this is how the room is heated. Electric baseboard heaters are normally installed beneath window both to take advantage of any falling cool air from the window and because windows are located on outside walls where heat may be lost due to low or no insulation.
Electric baseboard heaters can be cheap to install because they do not require any ducts to be used like in a central HVAC system. This keeps costs to a minimum when building an edition that would be difficult to heat or when remodeling an investment property. Electric baseboard heaters can also be a good option if you live in a climate that does not see very many cold days. They can be a good option versus installing a heat pump.
Electric baseboard heaters allow you to heat different areas of your home or office independently of one another. This can be advantageous for those who live in families or work in offices where one person is cold all of the time and the other person is always freezing. This can also be advantageous if you live in a large home and only want or need to heat your bedroom at night and do not want to pay to heat the entire home. For example, you could set your main thermostat on 65 degrees and in your bedroom have a baseboard heater set to 70 degrees. This way you can be warm in your bedroom at night.
For all of the advantages that electric baseboard heaters provide there are also disadvantages as well. The main disadvantage being electricity usage. Many people ask how much electricity electric baseboard heaters use. Do baseboard heaters use a lot of electricity? Typically electric baseboard heaters consume about 250 watts per foot. This means that if you have a 6 foot electric baseboard heater installed in your bedroom that it would consume about 1500 watts (250 watts per foot x 6 feet). Many people will tell you that baseboard heaters are efficient. And in regard to the amount of electricity that is turned into heat they would be correct. Because they are resistance type heaters they convert nearly 100% of the electricity into heat. However, do not be fooled. Heat pumps are more effective at keeping your power bill low than electric baseboard heaters are.
How much electricity does a baseboard heater use? Let’s do an example of how much a small home with only electric baseboard heaters could cost. For the example let’s say that the house if 1,000 square feet with 3 rooms and one bathroom. Each room has one 6 foot baseboard heater, the bathroom has a 2 foot heater and the living has two 6 foot heaters. So we have 5, 6 foot heaters and one 2 foot heater for a total of 32 feet of baseboard heaters. Remember from before that the average watts per foot is 250 watts. So 32 x 250 = 8,000 watts. So for every hour that the baseboard heater is on you will use 8,000 watts of power. Now let’s say that they run for 8 hours per day for 30 days. 8 hours x 8,000 watts x 30 days = 1,920,000 watthours. If we divide that by 1,000 we get the kilowatt hours which is what you are billed on and that equals 1,920 kilowatt hours. Now if we multiply that times say $0.10 we get $192.00 just to run your baseboard heaters to heat your home.
So, the biggest disadvantage is the usage of the electric baseboard heaters. Do they put off good heat? Yes. Are the cheap and easy to install? Yes. Are they expensive to run? Yes. There is one alternative and it is the electric hydronic baseboard heater. They use a liquid inside that is heated and radiates the heat in the room longer than the metal fins do. This means that they may run less often than regular electric baseboard heaters. But be aware that they also use the same wattage when they are running.
