Garage heating with electricity

In order to properly use garage features, you must first install a suitable garage heater. Usually, garages are made of concrete walls. As a result, many garages are already unbearably cold in the fall. Installing a garage heater can create additional usable or even living space.

First step: clarify the need

Before installation, it should be clear what the heater will actually be used for. There are some interesting options when it comes to garage heaters. Popular heating systems are mainly based on gas, wood, infrared, electricity, and solar energy.

Examples are:

  • gas heating (fans, radiators);
  • electronic heating from 1500 KW;
  • oil radiators, diesel heating;
  • wood stove.

Make the right choice in heating

A heated garage room is ideal for various works in winter. You can also use the garage as a regularly used living space or for a party. In most cases, the garage can be implemented with a simple heater. In this type of use, heating is very convenient and, most importantly, cheap.

However, garage space should be well heated, for example, with underfloor heating or electrically powered heating. There must be enough space in the garage room and ventilation.

When heating, for example, a window or a ventilation grille should provide an air supply. Without this, it will quickly become stuffy if used regularly. There are also rights and obligations that must be observed during remodeling work.

Different requirements for garage heaters:

For car:

  • Provide low humidity.
  • Permanent frost protection is useful.
  • Low acquisition costs, low maintenance requirements.

How to install an electric garage heater?

There are two styles of electronic garage heaters on the market, wired and corded. Corded models are the easiest to install and require the least amount of work.

Most corded electronic heaters are the easiest models to operate and install and since many of these heaters are floor units, they are incredibly portable. Simply plug your wired garage heating device into an area of your garage, usually next to the back wall facing the door, and turn it on.

Another style of corded garage heater is the ceiling or wall-mounted model. For these heating devices, install the unit with a mounting bracket in the desired location.

The main thing to keep in mind here is that you must ensure that the unit’s power cord can reach its electrical outlet and that the area directly below the unit is clear for at least 60 to 91 cm, to ensure optimal heat flow and prevent unnecessary safety hazards.

Installing a wired model is a bit more complicated, but you can easily tackle it yourself, although if you are inexperienced with this type of project, it is recommended that you hire an electrician.

To install a wired garage heater, you run a sheathed wire from the circuit breaker box to a junction box that you install where you intend to mount your heating unit.

You can also install a thermostat by running the wire to the thermostat first and then from the thermostat to the junction box. Once all the wiring is done, your new heating tool will run off of your home’s electrical system and all that needs to be done is mount the unit to your wall or ceiling with the help of a mounting bracket.

What size electric garage heater do I need?

Garage heaters are one of the smartest investments you can make if you plan to spend a lot of time tackling projects during the colder winter months. But while they are capable of making your garage warm and comfortable, choosing the wrong size is like throwing money out the window.

Why? Because if you buy one that’s too small, the heat it throws off simply won’t be enough to do the job and it will need to be replaced.

Also, if the unit is too small, the heater will run constantly, trying to meet the demands of your garage, increasing the cost of operation. And if your garage heater is too large, you’re overpaying for a model that’s producing too much heat and wasting unnecessary energy.

So how do you determine what size garage heater is perfect for your space?

While there are ranges available online, one of the most accurate methods is to perform the following calculation. With some accurate measurements, you can easily determine what size heater is perfect for your needs.

First, you must determine the square footage of your garage. To do this, you will multiply the length of the interior by its width. So, for a garage that measures 9 ft by 9 ft, your calculation will be 81 square feet.

Next, you’ll multiply the square footage of your garage by the ceiling height to arrive at the total cubic feet of your area. So, based on the example above, if your ceiling is 9 ft high, your calculation will be 9 x 81 = 729 sq ft.

You will now subtract the lowest winter temperature in your region from the temperature you wish to maintain in the garage to determine the temperature increase your unit should generate.

For example, if the winter low in your region is 21 F degrees, and you want to maintain a temperature of 158 degrees, your calculation will be 158 – 21 = 137 F.

Purchasing the right unit for your needs will save you money by allowing you to buy the most affordable model for your space while ensuring that your operating costs stay as low as possible. More importantly, you’ll be able to relax, knowing that your heater is perfectly capable of keeping your space warm and comfortable.

While this method is essential for some brands that don’t specify the heating coverage of their models, there is an option for anyone who isn’t interested in tackling math problems just to determine what size garage heater product is right for you.

Many of the better brands have decided to make it easy. While most models were only used to list the BTU heating output the unit was capable of, many of the most popular options now list the size of the area they are capable of heating a room.

Simply measure the square footage of your garage, look at the box or research the model online and choose a model that is capable of efficiently heating your workspace.

What’s the best heater for a garage?

If you’ve ever tried to tackle a project or do routine car maintenance in your garage during the winter, you know how unbearably cold it can be.

But by purchasing the right garage heating unit for your space, you can keep your garage warm and comfortable year-round. But before you buy any unit, you should consider two things: which style is right for your needs and which brand makes the best models on the market.

Type of garage heater: There are several styles of garage heaters available that allow these units to control temperatures differently. The three styles you will find on the market are convection, radiant and forced air models.

Convection garage heaters are designed with an enclosed flame or heating element that heats the air inside the unit. This heated air rises without the use of an internal fan. These are the most affordable units on the market and come in either mounted or portable models.

While great for a small space and perfect for someone on a tight budget, these models will take a long time to heat your workspace. Radiant garage heaters are designed with reflectors that redirect infrared heat, making them ideal for spot heating or, in the case of high-end units, for heating a large space. These models radiate heat into the workspace without the use of a fan, so if you’re a do-it-yourselfer and want to eliminate blowing dust and ruining the finish of a project, radiant models are ideal for your needs. And since these heaters are available in various sizes and come in electric, gas, and propane models, you can easily find the perfect unit for your specific needs.

Electronic models, while cheaper than gas-fired units, will cost more money to operate, as they will use electricity to generate the heat needed to warm your space.

Portable or Mounted

Once you’ve determined the style of garage heater that’s right for you, you need to decide whether you want a portable or mounted model. Stationary and portable models have their own specific pros and cons.

But by looking at each style individually, you’ll be able to decide which style is perfect for your needs. Stationary garage heaters are attached to the ceiling or wall of your garage. They are available in a variety of fuel, size, and price options, and most are capable of providing incredible performance.

The downside to these models is that they generally cost more than their portable brethren, but if you spend a lot of time in your garage, you’ll enjoy the fact that these models don’t take up floor space, you don’t have to worry about tipping the unit over or tripping over a power cord.

Portable units

Plus, if you need to use your unit elsewhere, you can just pick it up and go. There are a variety of styles, some are ideal for use as a spot heating tool and others are perfectly capable of heating large rooms easily.
