Top 6 Best 110v Garage Heater – Guide To Heating Your Garage

Most garage heaters are powered through 240-volt plugs. So, what do you do if you have standard plugs? Can you still use a 110v electric garage heater?

110 volts is still the most standard power outlet in many homes in the United States. These power outlets have spots for two plugs and are rated at 15 amps. If you have these standard outlets, you’ll be able to use any of the best 110v garage heaters in this review.

Remember, 110 volts and 120 volts are usually used interchangeably; think of them as one and the same.

110v Electric Garage Heater Comparison

Voltage Differences: 110V, 115V, 120V, 220V, 230V, 240V

It is easy to get confused with the following terms used to describe voltages: 110V, 115V, and 120V. Interestingly, these terms refer to the same thing. Any standard live wire in your house has a voltage rating of 120V. This voltage is in comparison with the neutral wire which has 0 voltage.

However, this level of voltage is not maintained during consumption. If you connect a long extension cable to a socket on your wall, the voltage at the end of the socket is likely to be lower than that on the socket. This voltage reading may drop from the original 120V to 115V or even 110V.

This means that if you connect an appliance to a long extension cord, the device will get less than 120V of power. Thus, for the appliance to function properly, it must be configured to operate with a lower level of voltage than the typical 120V.

Many typical household electric appliances are labeled with much lower voltages than 120V. The information means that you can safely use the appliances even when the voltage drops slightly.

Similarly, the voltage terms 220V, 230V, and 240V should not sound confusing to you. To understand what they mean, remember that the utility companies supply 240V of power to domestic customers. This means that the main supply in every home in the USA has a standard voltage of 240V.

However, the companies do not provide a single line with 240V into homes. The supply consists of two phases of 120V each operating at 180 degrees out of phase. This means that the voltage of your home (which is based on AC) alternates between -120V and +120V. The neutral line in the home is 0V.

If you choose to use both phases at the same time, then the voltage in the home alternates between -240V and +240v. These figures may drop slightly to -115V and +115 (leading to 230V) or even -110V and +110V (leading to 220V).

How to Choose the Right Voltage Heater for your Garage

Heaters come in a variety of voltages. Choosing the right voltage heaters is one of the most important decisions that you have to make when getting a heater for your home or office. If you end up with a heater of the wrong voltage, the chances are that you will not achieve the goal of heating your indoor space.

Using a heater with excess voltage on a low-voltage circuit is undesirable. If you install a 240V heater on a 120V circuit, then it is likely that the heater will not even turn on.

However, if it turns on, it will emit very little heat that may not even serve your purpose. Furthermore, when you connect a high-voltage heater to a low-voltage circuit, you will be running the risk of having a damaged heater.

Similarly, using a low-voltage heater on a high-voltage circuit is undesirable. If you connect a 120V heater on a 240V circuit, you will end up with a lot of excess heat.

The heater will get overworked and, most likely, damaged after a short time. Besides, the temperatures may rise rapidly and beyond the point required to keep the indoor environment cozy.

One way of determining the right heater voltage is by looking at the circuit breaker. The 120V circuit breaker is visually different from the 240V one.

Whereas the 120V circuit breaker has figure 20 marked on its surface, the 240V one has figure 15 marked on the surface. You can use this information to ensure that you get a heater of the right voltage for your house.

Alternatively, you can use a voltmeter to determine the voltage of the heater. However, remember that using a voltmeter to determine the voltage of heaters of any other electric appliance is a high-risk activity because live wires are involved. Ensure that you observe all the recommended safety precautions during the process.

Garage Heater Types and Costs

Electric garage heaters convert electric energy into heat energy. The heat energy is then used to warm the air in indoor and outdoor spaces, in this case, the garage.

Electric heaters vary in terms of design, heating capacity, and mounting options. Some electric heaters have modern designs that are used to enhance the aesthetic value. For others, functionality s more important than aesthetics.

Electric heaters can be used as freestanding devices or mounted on the wall or ceilings. It is also possible to keep electric garage heaters on a flat surface in your garage. Heaters that are usually mounted on the ceiling or wall are sold with special brackets.

The main cost of electric heaters is electric power. This largely varies with the capacity of the heater and the length of time that you keep the device on.

However, it is typical for people to pay an additional $80 on their monthly electricity bills as a result of using an electric heater as a source of supplemental heat.

Propane Gas Heaters

These heaters burn propane gas to produce heat. Most propane gas heaters are designed to be used in outdoor environments. This is because the burning of propane produces the highly-toxic carbon monoxide gas. However, it is safe to use propane heaters in your garage.

The main cost associated with propane heaters is installation. You may need the services of a certified expert to ensure that the installation process is properly completed. Occasionally, you may have to conduct basic maintenance procedures to keep the heater in excellent working condition.

Natural Gas Heaters

Installing a natural gas heater in your garage may cost you $1,000. This amount covers the fees of a certified HVAC technician and other additional items that you may have to purchase.

However, just like is the case with propane heaters, it is easy to operate natural gas heaters. The prices of natural gas and propane are lower than those of electric power. You may also incur small additional costs of maintaining or repairing the heater to keep it in good shape.

What Size Electric Heater Do I Need for my Garage?

garage heater size

The size of an electric heater that is appropriate for heating your garage depends on several factors, including the insulation level and size of your garage.

Garages that have normal insulation levels neither require additional nor less heating than those with either high or low insulation levels. Similarly, large-sized garages will require more heating than small-sized ones.

The standard method of determining the right size of the heater for your garage involves calculating the size of the garage and then converting this value into wattage requirements.

It is assumed that for every 1 square foot of space, 10w of power is required to keep the temperature within the desired levels. However, this may greatly vary based on the factors mentioned here.

For demonstration purposes, we can assume that a garage measures 20 feet by 20 feet. Therefore, the surface area of the garage is the product of its dimensions, which is 400 square feet. In effect, the garage requires 4,000 watts of heat.

However, this figure will not be helpful because the heating size of garage heaters is usually indicated in British Thermal Units (BTUs). To convert wattage into BTUs, we multiple our values with a factor: 3.41. Therefore, 4,000w is equivalent to 13,640BTUs.

You may have to make a few adjustments to the BTU value based on the insulation level of the garage. If the garage has a lot of openings, then it may be wise to adjust the BTU value upwards by a small percentage (10 or 20).

The additional BTU value will cover for increased draftiness. Conversely, you may need to reduce the BTU by 10% of 20% if the garage is warmer than normal. You can then look for a heater that has BTU values that fall within your range.
