Choosing a heating system for your shop or garage can prove to be a challenging task if you’re unsure what to look for. This guide covers the basics of what you need to know in buying the best shop heater for your work space. Before you buy, there are some factors you will need to consider.
It’s hard to work with numb fingers when temperatures reach bone-chilling digits. Since most workshops and garages have very little, if any, insulation, it can get pretty frigid during the winter months. Winter weather and freezing temps can also be bad news for woodworking. Cold temperatures can cause glues and finishes on wood to not dry properly. Even worse, freezing temperatures often causes wood and lumber to crack as moisture is drawn out from the cold, dry air.
A heating system for your workshop will allow you to work comfortably year-round. When it’s time to install a shop heater for your workspace some very key points can help you in achieving better efficiency and cut your energy costs.

Why A Conventional Space Heater May Not Be Best for Your Shop
If you have a small workshop or work out of a home garage, you may be thinking a conventional heater such as a space heater is sufficient. The type of work or materials that are being used frequently in a shop could pose a serious risk with conventional heaters. Factors such as dust from woodworking, paint particles or spray finishes could pose a fire hazard, not to mention often result in burner issues with conventional heaters requiring the need for service calls.
Types of Shop Heaters
Heating units come in various forms. When you’re considering efficiency in terms of cost and heating adequacy it’s important to know the difference in what each type of unit has to offer. If you know very little about how heaters operate, it can get confusing when trying to decide which type of heating system is right for your space.
A gas or electric forced-air shop heater blows out warm air to heat up a room. This is the more economical option especially if hooked up to natural gas. Keep in mind, however, this heater blows out air which will stir up dust particles along with it. This would not be an ideal choice heater for a woodshop where you will be frequently cutting wood or working on painting and finishing projects.
Mr. Heater MH60QFAV | 60,000 BTU Propane Forced Air Heater
Forced-air gas heaters require a vent typically routed through the attic and roof or through a sidewall. Some models include a vent kit with it. It also requires an electrical hookup to power the blower so placement should be near an electrical outline in addition to the gas line. For woodworking shops or where paints and finishes may be frequently used, a heater with a separate combustion chamber is recommended. These types of heaters are designed to draw in fresh air from outside rather than circulating paint and dust-laden air.
Infrared Shop Heaters
This is a type of gas heater which radiates heat by heating up objects in the room that in turn radiate heat into the air. For woodworking projects and workshops infrared technology offers the best shop heater as it doesn’t stir up dust or particles into the air. If your shop has concrete floors this type of heater will provide more uniform heat throughout the shop for a more comfortable working environment. An infrared shop heater also maintains the humidity levels so it won’t affect materials such as lumber.

An important safety factor to consider when installing this type of heater in a garage or industrial shop is location and proximity to combustible materials. In order to feel the immediate effects of the warmth this type of heater produces you need to be within a certain range. It takes much longer to heat up an entire room as opposed to forced-fan air heaters. Be sure to read clearance requirements for these types of heaters prior to installation and ensure safe distance from combustible materials.
Electric Garage Heaters
Electric heaters are a popular choice among consumers as they’re easier and safer to install. An electric heater generates heat using electrical energy and generally uses a built-in fan to disperse heat. Many portable units use a standard 110-120 volt plug; however the units designed for industrial use often require 220-240 volt. This is an important factor to look at before purchasing as well as the required circuit breaker.
Choosing the Right Size
Finding the best shop heater for your workshop will require some measuring to get the right size. Trust me when I say this isn’t something you want to take a guess on especially if you’re looking to save on energy costs. If you’re going in blind hoping to get help from an ‘expert’ at a hardware or department store for a shop heater, they may convince you that a ceiling-mounted heating system designed for a warehouse is what you need.
An oversized shop heater even on a low temperature setting will frequently cycle and waste energy. Likewise, some industrial heaters require a minimum clearance of 8 feet from the base of the unit or require special permits for use in a building with 7-8 foot ceilings. On the other hand, a unit that is too small for the size of your garage or shop will not heat it up effectively and can run the risk of overheating trying to reach the set temperature.
NewAir G73 | Electric Garage Heater | Heats up to 750 sq.ft.
Choosing the right size heater for your workshop should be based on the following:
- Square footage of your garage or workshop
- Ceiling height
- Climate zone you live in
The amount of heat a unit puts out is measured in BTUs (British Thermal Units) and this number can help provide a general idea on what size model you need. The general recommendation for smaller workshops and garages such as a 1-2 car garage is a radiant or infrared heater. A fan-forced air heater that produces 1500 watts is also a suitable option. For larger work spaces where you want warm air throughout the entire garage consider a gas-fueled unit or a 4,000-5,000 watt heater for effective heating capability.
Buildings that are not insulated, especially larger buildings, will require a heater that can produce more heat. This means choosing a model with a greater BTU rating. These types of buildings are also known for losing heat quickly when the garage door is opened and in particularly colder climates. The best shop heater types for non-insulated buildings are infrared or radiant heaters.
Installation and Safety Guidelines
When choosing any type of gas shop heater it is highly advised to have it properly installed by a professional installer or the gas supplier. It is critical that installation is done properly to meet all guidelines, codes, and requirements. If any adjustments, alterations, service or installation is not done properly it could result in serious injury or even death. If you don’t really know what you’re doing, let a trained professional do it!

You should also be sure the unit you’re considering is rated for use in the type of building you have. For instance, if you work from a home garage or out of a residential workshop industrial heating units will not permitted by building inspectors.
With electrical shop heaters most are too powerful to plug into a common household outlet. Most workshops are already wired for more powerful appliances, but if your unit will be hardwired directly you need to be sure all wiring meets the national and local codes. Plug-in models are much easier to install but still require a circuit that meets the amperage and voltage the unit requires. For hardwired electric heaters you should consider having a trained electrician install the unit if you aren’t familiar with wiring and circuit requirements.
VIDEO | How to Install A Gas Garage Heater
For gas or alternative fuel-run heaters you will need a ventilation system. Heating systems that run on alternative fuels produce by-products, particularly carbon monoxide. A fully or well-insulated garage is not ideal for a gas or fuel sourced heater as they typically don’t have a proper ventilation system. Putting in a ventilation system will reduce the efficiency of the insulation and can add to your total cost. In addition to having proper venting in place, a carbon monoxide detector is also recommended.
