A garage is one place that is difficult to warm in the heart of winter. One of the reasons is that the central heating system isn’t always enough to boost the garage’s temperature. If it’s detached, it’s even worst because you have to find another alternative to get the warmth in there.
One of the popular types of garage heaters is electric space heaters. However, most of them will increase your heating bills significantly. If you like spending time in the garage even in winter, you want to find a heater that will provide the needed warmth without cranking your heating bills.
An excellent option would be gas ceiling heaters for garage. At one end, these units are energy efficient than electric heaters and provide clean heating. On the other end, they save floor space that you can use to store other tools and equipment.

How Much Does It Cost to Run a Natural Gas Garage Heater?
The cost of running a natural gas garage heater depends on the length of time during which the heater is on and the unit cost of natural gas.
You can control the length of time during which the heater is on. The time depends on the heating requirements of your garage and your preference.
Natural gas is measured in units called therms. One therm of natural gas contains 100,000 BTUs. If you have a natural gas heater with a standard capacity of 30,000 BTU rating, then it will run for about 3 hours on one therm of natural gas.
The unit price of natural gas is $0.28 per hour. If you run the heater for 10 hours every day for a month, then the cost of keeping your garage warm for the entire month would be $84.
Gas VS Electric Garage Geater – Which is Better?
Both electric and gas heaters provide reliable and effective sources of heat for garages. However, there are essential differences between the two sources of heat that you may need to consider when deciding which heating method to use.
It is cheaper to run a gas heater in your garage than an electric heater in terms of cost. Electric heaters that depend on electric current to generate heat have higher operational costs than heaters, which burn natural gas to produce heat. The unit price of electricity per hour is higher than that of natural gas, which is $0.28.
There are significant differences in the installation costs for electric and gas heaters. Electric heaters are sold in a ready-to-use form. You only need to connect them to the mains supply and turn them on to have a warm room.
Gas heaters may need to be vented either through the wall or the roof of your garage. The venting process is detailed and requires the input of a technician. Furthermore, to use gas heaters in the garage, you will have to reroute the main gas line.
This procedure, in most cases, is expensive. As a result of these differences, the cost of installing a gas heater is by far higher than that of installing an electric one.
Gas heaters are noisier than electric heaters. When electric heaters get turned on, they produce low-level noises in the form of buzzes or pops. However, the noise subsidizes after some time.
Gas heaters are quite noisy because of two reasons: the combustion process and fans. For heaters that have inbuilt fans, their operation is quite loud.
Even for the gas heaters, which do not have fans, a considerable noise level is produced as the natural gas gets burned in the combustion chamber. The noise of the burning gas may be amplified if your garage is large and empty.
How Do you Size a Natural Gas Garage Heater?
It is not easy to determine the accurate size of a natural gas heater for a garage because many factors affect garages’ heating requirements.
Garages are typically drafty than indoor rooms. As a result of garages’ drafty nature, a lot of heat energy is wasted to the outside environment. Thus, it would help if you produced enough heat energy to compensate for the losses.
Also, the insulation level of garages is often more insufficient than that of the main indoor spaces. Poor insulation of the garage means that a lot of heat energy is lost through crevices and other openings.
Similarly, you must consider the amount of heat energy that is lost and factor it into your calculations for the garage’s heating requirements.
To quickly determine the size of a natural gas heater suitable for your garage, first determine the area of the space by multiplying the length by the width. If you have a square garage that is 200 feet wide, then its area will be 400 square feet.
Second, divide the area of the garage by 200 before multiplying the answer with 9,000. The final answer will be the number of BTUs needed to keep the garage warm.
In our example, the total number of BTUs needed to adequately warm the garage would be 18,000. You will work with this figure when selecting a natural gas heater for the garage.
However, it is necessary to consider other factors such as insulation and even the height of the garage ceiling. Garages or any high ceilings spaces have higher heating requirements than those with lower or average ceiling heights.
Picking a heater for your garage doesn’t have to be challenging if you know what to look for. The most important factor is to estimate your room’s size and determine how many BTUs you’ll need.
Most gas ceiling heaters for garage have higher BTU levels and will be enough for 2 or 3 car garages. If you’re asking for only one heater, I’ll recommend Modine HDS45AS0111 Natural Gas Hot Dawg Garage Heater because it’s big enough for 2 to 2.5 car garages.
