On this garage heater review, we’ll kick off by taking a look at the best 2 car garage heater to keep your room warm during winter.
We’ll also discuss 2 car garage dimensions and sizes, the level of BTUs you need, garage heater placement, and the average temperature for your garage to prevent condensation that could potentially damage a lot of things in there.
It’s important to realize that different heaters have their pros and cons, which is why you need to choose one depending on your needs.
Let’s dive into the best heater for 2 car garage reviews.
What is the Standard Size of a Two Car Garage?
Getting the right dimensions for your two-car garage will enable your ample space for parking the cars and loading and offloading them. You may need additional space in your garage for other activities.
The activities may include carrying out your hobbies down in the garage. Here is a brief discussion of how you can determine the right dimensions of a garage for two cars.
First, consider the size of the cars when determining the dimensions of your garage. The size of the cars is not uniform. Some cars, such as pickup trucks, may be as large as 16 feet long. This largely varies with the design. Measure the length and width of the cars that you intend to store in the garage.
Once you have the lengths and widths of the cars, add a few feet of space to enable you to maneuver around them while inside the garage. The extra space may be any figure from about 30 inches.
You need extra space for storage and other activities. Typically, a space of about 4 feet will be enough for one to store a few things within the garage. The extra space depends on what you intend to do in the garage and your preferences.
However, remember that every additional unit of space will cost you extra money for construction.
Additional space is also required for the door. 2-car garages can have either one large door or two separate ones. The choice of the type of door is a personal choice. Large doors that measure about 16 feet wide are usually enough to cover a 2-car garage.
Alternatively, you may install two doors, each measuring 9-feet on your garage. Nevertheless, remember to leave an additional space of 2 feet on each side of the door.
After all these issues have been factored in, the final size of a 2-car garage door may be between 20 square feet and 24 square feet.
How Many BTUs Does it Take to Heat a 2-Car Garage?
Understanding the number of BTUs needed to heat your 2-garage space will help you in choosing the right device.
If you install in your garage a heater with less heating capacity than what is required, then you will not have the desired level of comfort. Cold zones are likely to develop in certain areas of the garage as the small heater struggles to cover the entire size.
You can estimate the number of BTUs needed to keep the garage warm by following this procedure. First, determine the area of your 2-car garage by multiplying the length and width. If your garage measures 20 feet by 20 feet, then the area is 400 square feet.
Divide the area of the garage by a factor of 200 and then multiply the result with a factor of 9000. For a square-shaped 2-car garage that measures 400 square feet in area, the total number of BTUs required will be 18,000.
However, you may have to factor in the level of insulation of the garage before settling on the number of BTUs. If a garage is heavily insulated, then it may be wise to reduce the required number of BTUs by 10% or 20%. Finally, choose a heater with a capacity that is at least the number of calculated BTUs.
There is no one temperature level at which you should maintain your 2-car garage. In practice, the ideal temperature depends on several factors, including the location of your garage, weather seasons, and your preferences.
It is always necessary to keep the temperature of the garage higher than the prevailing dewpoint. If the temperature falls below the dew point, then the resulting accumulation of moisture may cause the development of mildew on the surfaces of your garage.
Moreover, if the temperatures of your garage fall to very low levels, such as 32 degrees Fahrenheit, the resulting weather conditions may cause damages to your car batteries.
It is wise to maintain the temperature of your garage at any level between 65 degrees Fahrenheit and 85 degrees Fahrenheit. This temperature range is important as it keeps the batteries of the cars safe and the mildew away.
Moreover, the temperature range of between 65 degrees Fahrenheit and 85 degrees Fahrenheit is ideal for keeping the environment in the garage cozy. You can comfortably work on your side projects when the temperature in the garage remains within this range.
Where should I Place my Garage Heater?
The correct placement of a garage heater can immensely contribute to making the space ideal for anyone to stay in for a long time. Also, correct placement of the heater can ensure effective heating and efficient utilization of electric power, if you are using an electric space heater.
For typical wall-mountable electric space heaters, ensure that you place them on walls that are directly opposite the garage door.
The heater should face the garage door to ensure the effective distribution of the heat across space. Moreover, when the heater faces the door, its effect directly counters cool air drafts that get into the garage through the door.
Ensure that your heater is positioned far away from combustible materials. This applies when you use your electric or gas heater is freestanding or wall-mounted. Ensure that all combustible materials, including fabric and plastics, are placed at least three feet from the heater for safety reasons.
