Heating a large space such as a large living space or a warehouse can be a bit challenging. You will need to carefully look at possible options and weigh the pros and cons of each of them.
The best way to heat a large space, in the long run, includes forced air systems and radiant floor heating systems. But for temporal or short-term heating, smaller and portable heaters such as space heaters will suffice.
But you need to keep in mind that finding the best way to heat a large space will also depend on a number of factors, including the size and layout of the space, and the budget available for heating. In general, the most common ways to heat large spaces include:
- Forced-air heating systems, use a network of ducts to distribute the heated air throughout the space.
- Radiant heating systems, use radiant heat to warm the space directly, without the need for ducts.
- Boilers, use heated water or steam to warm the space.
- Electric heaters, use electricity to generate heat in specific areas.
Additionally, it is always important to ensure that the space is well-insulated to prevent heat from escaping and to go for energy-efficient heating systems to minimize costs. It may be helpful to use a combination of heating methods, such as radiant floor heating and forced-air heating, to create a more comfortable and evenly heated space ( though this can be costly)
Challenges of heating a large space
Heating a large space such as a warehouse or a commercial building can be challenging for a few reasons. One of the main challenges is the sheer size of the space, which can make it difficult to heat evenly and efficiently.
Another challenge is the fact that these types of buildings often have high ceilings, which can cause heat to rise up quickly leaving colder air underneath, making it harder to maintain a consistent temperature throughout the space.
Additionally, large buildings often have a lot of windows and doors, which can also make it difficult to maintain a consistent temperature by letting heat escape.
On top of that, heating a large space can be expensive, particularly if the building is not well-insulated or if it is located in a region with extremely low temperatures.

Best way to heat a large garage
There are several ways to heat a large garage and some options to consider include: (from least to most effective)
Space Heaters
Space heaters are a portable and affordable option for heating small areas of a large garage. Depending on the area to heat, you might need to place many units to adequately heat your entire garage.
Space heaters were created to warm a single room or tiny area, so they might not be effective at heating a big garage on their own. Nonetheless, they can be utilized to supplement other heating resources or to provide targeted heat to certain locations of the garage.
To make use of a space heater to heat a huge garage, you’ll need to choose a heating system with enough power to heat up the area. Heaters are rated by their BTU (British Thermal Unit) result, which shows the amount of heat they can produce. For a huge garage, you’ll likely need a heating unit with a high BTU outcome, such as 10,000 BTUs or even more. Such as the Mr. Heater unit below…
- 10,000 BTU Natural Gas heater to heat spaces up to 250 sqaure feet.
- Radiant heat burner
- Automatic low oxygen shut-off system (ODS). CSA Certified
- Operating this heater at altitudes over 4,500 FT above sea level could cause pilot/ODS to shutdown the heater.
- Legs and wall mounting hardware included
To take full advantage of the effectiveness of a space heater in a big garage, you ought to additionally think about the following:
- Positioning: Put the heater in a central location or in an area where you’ll be spending a lot of your time, such as near a workbench or device storage space area.
- Insulation: Shield the garage to minimize heat loss and also enhance the effectiveness of the heater. This can consist of adding weatherstripping to doors and windows, sealing voids and splits in the wall surfaces and also the ceiling, and also including insulation to the wall surfaces as well as the attic.
- Ventilation: Appropriate ventilation is very important to make sure the safe and also efficient operation of a space heater. Keep windows and doors open up to permit fresh air to flow, and also ensure the heating system is positioned in a well-ventilated area.
- Timing: Make use of the heater only when you remain in the garage, and transform it off when you delegate conserve power, and lower the threat of a fire.
By following these tips, you can use a space heater to help heat a large garage, but it may still be necessary to supplement with other heating sources that I have listed below to fully heat the space.
Gas or Propane Heaters
Gas or propane heaters are a more powerful option than a space heater and can heat a larger garage more efficiently and also can operate independently of an electrical power source. They can be mounted on the wall or ceiling, and some models come with a thermostat to help you control the temperature.
Nevertheless, they do call for a reliable source of gas, such as a propane tank or gas line, as well as they may be extra expensive to operate than various other types of heating systems.
To utilize a gas or gas heating unit to warm a huge garage, you’ll need to choose a heater with sufficient power to heat the space. For a large garage, you’ll likely require a heating unit with a high BTU output, such as 30,000 BTUs or even more. This is one I have used in the past…

Forced Air Furnace
If your garage is attached to your home, you may be able to use the same furnace for the house to heat the garage as well. This can be an effective way to heat a large garage, as it can distribute heat evenly throughout the space and can be controlled with a thermostat.
To use a forced-air furnace to heat a large garage, you’ll need to connect your network of pipes or ducts to flow to the garage. Help from an HVAC tech may be required to install it properly.
Radiant Heaters
Electric radiant heaters are another option for heating a garage. They work by emitting infrared radiation, which warms objects and people in the room rather than the air itself. This can make them more efficient than other types of heaters.
To heat a large garage with a radiant heater, you would need to determine the size of the garage and the amount of heat needed to maintain a comfortable temperature.
One option would be to install multiple radiant heaters around the garage, spaced out in a way that will ensure even heating throughout the space. You could also consider installing a radiant heating system under the floor, which can be an efficient way to heat a large garage as it heats the entire floor evenly.
It’s important to consider the size of the radiant heaters you choose, as well as the power output and heating coverage of each unit. You may also want to consider installing a thermostat to help regulate the temperature and ensure that the garage stays at a comfortable level.
Infrared Heaters
Infrared heaters work by emitting infrared radiation, which is a type of electromagnetic radiation with a longer wavelength than visible light. This is absorbed by objects and surfaces in the garage, warming them up. These heaters are typically mounted on the ceiling or wall, and can be an efficient and cost-effective way to heat a large garage.
