How To Choose Best Heater For Uninsulated Garage?

There are a few factors you should keep in mind before you buy a heater for a garage that is not insulated. Based on these factors, you will be able to determine which heater is right for you.

1. Heating Method

Uninsulated rooms can be heated using a heater in a few ways. When compared to electricity, natural gas and propane are more cost-effective. It must, however, be installed by a licensed individual with permission from the local authority. Heat may be provided by the following methods:

  • Radiant Heater:  Infrared rays are used to heat the room with radiant heaters. Spot heating is achieved by diversifying the heat outwards using polished reflectors. A campfire is a good analogy. An air-forced heater blows air, but radiant heaters don’t. Natural gas, propane, or electricity can all be used as fuels for this heating method.

Those who like pointed heating methods in a particular direction, such as DIYers or woodworkers, should consider this heating method. As a result of this method of heating, dust is not blown up and ongoing projects are not damaged. There are a variety of sizes and prices available for radiant heaters that can be mounted or carried.

  • Forced-Air Heaters: A forced-air heater distributes heat evenly throughout a room or garage with the help of a fan. Various sizes and prices are also available, as well as different methods of powering the heaters, including AC power, natural gas, gasoline, or natural gas. The natural gas line is connected to it when it is powered by gas.

Whenever fan-forced heaters require airflow, as they produce water vapor and fumes, they blow dust particles into ongoing projects, ruining them by generating a lot of dust. These types of heaters are ideal for garages or storage rooms where woodworking is prohibited or DIY projects aren’t permitted.

  • Convection Heaters: Convection heaters use the principle of enclosed flames to heat an area without any fan power, using the convection heating process. Despite the fact that it takes a little while for it to warm up, this heater is pretty efficient at heating a room, even though it does not provide intense heating like a radiant heater or a forced-air heater. Generally, convection heaters come in either baseboard mounting or portable forms, and you can find them in all shapes and sizes.

2. Power

BTUs (British Thermal Units) or Watts are commonly used to measure the power of industrial heaters. If there isn’t enough insulation in the room, you may want to bring in a heater that has a bit more power. On the opposite side of the heater, winter temperatures are lower without a central heating source.

3. Safety Features

As well as considering the electrical features, safety measures should also be considered when buying a garage heater.

  • Exterior with CoolTouch: The heater’s outer material is plastic or fiberglass, both of which conduct heat poorly, so it remains cool even after producing heat. Portable or wall-mounted heaters are most likely to have these exteriors.
  • Protects against overheating: If the temperature reaches a certain limit, the power button will be automatically turned off.

4. Hardwired or Plugged-in

In a compact room, hardwired installation saves valuable space as it is fixed to a wall or ceiling. In order to connect the hardwired heater, there needs to be the main power source.

In comparison to hardwired heaters, plug-in heaters require no wiring and are faster to set up. In particular, they are ideal for people who don’t use them frequently.

5. Type

A space heater’s power source and heating mechanism determine the best one for an uninsulated garage. Infrared, convection, and panel heaters all use various modes to transmit heat.

Due to their use of fans to distribute the heated air throughout the room, convection heaters are considered to be the most energy-efficient and consistent models. Their coverage is greater, but they are slower and noisier.

A quartz heater or radiant heater is another form of infrared heater that is ideal for small spaces since it quickly heats both the ambient air and the people in the room. Turning off an infrared heater will make you feel cold.

By combining radiant and convection technology, micathermic panel heaters ensure fast and efficient circulation of warm air throughout the room without using fans. Lightweight, compact, and energy-efficient, they are quick and quiet.

Radiators with an oil fill: Heat is produced permanently by oil-filled reservoirs in portable electric models. The heat is distributed by natural air circulation, so they are hot to the touch and slower. The slim, compact design makes it easy to carry around, and they never need to be refilled

Using ceramics: To heat up large garages and maintain target temperatures, they use an electric model that utilizes a self-regulating ceramic. The surfaces remain cool.

These heaters are powered by propane, natural gas, or liquid petroleum gas.

Since they connect to a gas line and require proper ventilation, natural gas garage heaters for uninsulated garages need professional installation. The cost of installation is higher, but maintenance is lower since they do not require refueling.

It is necessary to purchase gas tanks and hose attachments separately for propane products. Electronic ignition may be included for quick start-up and adapters for custom attachments. When there is no power, they can be carried or mounted on walls, making them convenient to use during a power outage.

6. Coverage area

A model’s coverage area is the maximum area it can heat effectively and efficiently, expressed in square footage.

For effective garage heating, your primary heating source should generate at least 10 watts per square foot. Nevertheless, this rule may vary depending on whether your space heater provides primary or supplemental heat, and what type of heating technology it uses.

It is also possible to reach a wide area with some portable products. You should take measurements of your garage, considering things such as the height, insulation level, and window count that may indicate a larger heater is necessary.

In order to achieve optimal performance, it would be best to choose a model that offers more coverage than you need, as the model will be able to handle sudden changes better. Even when the heater is running on low settings, the output will still be maximized and you will be able to reach your target temperature in a shorter period of time.

Avoid unnecessarily consuming large amounts of energy by adjusting the coverage a little higher than recommended. Too small a heater is also a bad choice because it will overheat due to excessive use.

7. BTUs/watts

The British Thermal Unit (BTU) is a standard measurement used to determine how much heat can be produced by a particular heater. If you need to maintain a consistent temperature and withstand temperature fluctuations in garages without insulation, crawlspaces, and high ceiling spaces.

You should choose a natural gas garage heater with a larger BTU capacity. By comparing the heater’s BTU rating and wattage, you can determine the heater’s energy efficiency.

8. Mounting

It is possible to mount heaters on walls and ceilings in both portable and fixed forms. A certified HVAC technician hardwires a natural gas garage heater to vents and gas lines in uninsulated garages.

Mounted:  Since they are hardwired into an existing connection, they are the best space heaters for large, uninsulated garages. Professional installation is expensive, which is one of their downsides. These fans draw cold air from the outside or disperse warm air down by mounting them on walls and ceilings. Basements are commonly equipped with baseboard models. Installation is easy and they are quiet.

Compact design: Compact, lightweight, and often with legs or wheels to ease installation and relocation, freestanding units can also be called standalone or freestanding units. There are some cord storage units onboard, and some are plugged into electrical outlets. Place them on the floor, table, or nightstand for focused garage heating. They are ideal for small spaces

9. Dimensions

Uninsulated garages require space heaters that can be conveniently mounted or moved without taking up much space. It should be mounted on a wall or ceiling, leaving enough space for any ventilation hoses and sufficient clearance from the wall.

Portable natural gas garage heaters for uninsulated garages should be equipped with a handle or wheels to facilitate easy transportation. The Lasko 5160 Ceramic Tower Heater is an example of a standalone model with a space-saving cylindrical shape.

You need to consider your space and mounting type when determining the appropriate size. Those heaters that process large volumes of air generally have larger motors and fans, so they will be larger in size.

10. Warranty

A limited 3-year warranty is included with the Lasko 5160 Ceramic Tower Heater. A one-year limited warranty is usually included with uninsulated garage heaters powered by propane or natural gas.

Additionally, different brands offer different warranty periods for different components, like a one-year heater warranty and a three-year motor warranty. You could lose your warranty if you use the wrong applications and attachments.

Some examples include converting propane models to natural gas without first confirming compatibility, or using garage heaters in bathrooms and damp environments.
