A good garage is a warm garage. Even the most economical car enthusiasts agree with this claim. A time in winter, the Belgian four-wheeled friend was forced to endure severe frosts that are slowly turning into the past. Car owners have been convinced that even minimal heating costs in winter are not as high as repairing a car that often freezes in the winter. Many people are also attracted to the opportunity to start the car right away, rather than waiting for it to warm up.

It's not difficult to solve the heating problem, as the store offers a wide range of electric, gas, diesel and infrared garage heaters. It's still to choose the appropriate model. Please read our article carefully to select the best garage heaters for you and your family.

Buying Guides

Manufacturers offer car owners the most varied models of heaters for temporary heating. Users can operate them on electricity, diesel fuel, liquefied gas, etc. When figuring out which are the best garage heaters, one should consider the room's area, how well it is ventilated, the acceptable air temperature, and other factors.

1. Model Options

The first option is a diesel-powered heater. The combustion is powered by an air-pump fan, which requires a small amount of electricity to operate such a device. Hot air enters the heat exchanger and then spreads throughout the room. Combustible products are removed through chimneys. 

Using a diesel heater, you can warm up very quickly, even in a room without insulation. These are compact devices that can be installed anywhere suitable. It should be remembered that during diesel heater operation, oxygen contained in the room is consumed, so care must be taken to ventilate the garage. Modern models are equipped with remote control. The long-term operation of such a device is considered entirely safe.

The second option we want to mention is a gas heater model, a more modern version of a gas heater. The device is equipped with a thermostat, allowing you to change the temperature to heat the air and save fuel. The protective case of such a device can heat up to 60 degrees. This reduces the risk of fire or burns, but care should be taken when handling the gas heater.

Although the costs for units operating on liquefied gas are pretty high, moderate fuel consumption allows you to recoup these costs during the first few months of operation. This heater is considered to be the best choice for a garage that is only heated periodically.

Next, electric heaters are the standard model of today's garage heaters. Electric heaters are extremely easy to operate. They must be installed in the right place, then connected to a power source. The thermostat's presence enables you to regulate the heating of the air in the garage. Arguably, electric heaters are the most accessible and most affordable way to organize heating in a garage. These are safe and convenient devices, but their operating costs can be pretty high.

Last but not least, infrared heaters are great for continuous heating to prevent the engine from freezing. Infrared heaters are convenient because they can be placed on the ceiling, directing radiation to the floor. Therefore, you can quickly and effectively warm up the entire room. The use of devices of this type is relatively safe and economically beneficial, as the energy consumption is much lower than when using traditional electric models.

In general, each garage heater has its features and characteristics that suit every kind of garage. Please calculate carefully to choose the most suitable option.

2. Engine Power

If you choose a garage heater for the garage, you need to calculate the desired device's strength. This requires data on the number of windows, insulation, and floor space. Only after the assessment can you decide the number of the best garage heaters and how much energy to receive. Calculations are often performed by experts taking into account more factors. It is essential to understand that not having a definite formula will allow an inexperienced person to decide the required strength independently.

3. Main functions

Before buying any unit each person complies with specific criteria that they like. When choosing a heater, the features are as follows:

  • Air exchange: This indicator is significant for the heat gun. The higher this value, the more heat currents accelerate, and as a result, the room heats up for a short period.
  • Ability to change modes: It is very convenient to change its capacity during the heater's operation. It is also economical, as some devices have minimal heating that can operate without refueling for two weeks.
  • Timer Setting: With its help, you can set a time of intense heating, after which the heater will turn off on its own.
  • Noise level: When the diesel heater is working, there will be noise in all cases. This is a fundamental metric. Then it must be taken into account. Note that a 45 dB reading may be considered adequate.
  • Auto-off function when overheating: If the case falls accidentally and the heater starts to overheat, there will be no fire danger, such as the thermostat will operate.

4. Materials

The metal casing is much better than plastic and composite. First, the metal is more substantial, and second, if the electricity is cut off enormously, the red hot electric heater will not harm the metal body of the heat gun. At the same time, the plastic can melt and cause a fire.

5. Machine shape

Cylindrical devices can warm a room many times faster because their heating element is a spiral. This option is more suitable for an electric garage if you need to heat the car in the morning quickly.

The selection of a rectangular thermo-electric heater might also be available for the garage, but it is suggested to be more affordable for heating a home and private home. That's because rectangular heaters are connected to the type of internal heating element - a mesh, which doesn't dry out the air and is less dangerous than spontaneous combustion.

1. Are the Garage heaters worth it?

In general, if you use your garage for anything other than parking your car or storage space and spending any time inside, it's well worth it. In case your garage is not insulated, any heat you give to it can essentially be lost out the door, through the wall, or the roof.

2. Is a hot garage harmful to my car?

Frequently, people believe that a hot garage is even worse for their car. In contrast, a heated garage is even better for your vehicle. When your car is covered in snow or salt, storing it in a garage warm every night can speed up the rusting process a bit.

3. What is a suitable temperature for the garage?

The temperature depends on how you use your garage and where you live. A good rule of thumb is always keeping your garage above the average dew point to form steam. This is typically around 40°F for inland states and around 65°F for coastal conditions.

4. Is the infrared garage heater good?

Garage heating is the solution. The infrared heaters work well in shack buildings built outside or away from home. Additionally, infrared garage heaters keep the rooms above your garage warm. Infrared garage heaters heat people and objects directly, heating the ambient air to the set temperature.

5. What capacity electric heater do I need for my garage?

It is advisable that when sizing a heater is 10 watts per square foot. For instance, some electric garage heater like NewAir Garage heater has a capacity of 5600 watts, which means it can efficiently and effectively heat an area to 560 square feet.
