Garage Heater Buying Guide and FAQ
Types of Garage Heaters
Garage heaters can take many forms based on what you require in your workspace. From small personal heaters right up to units that are capable of heating cavernous job sites there is a heater that would be perfect for your needs. As a basic rule of thumb, electric heaters have a ten to one ratio of watts to square footage heated. Therefore a 3000 watt heater will heat a space that measures 300 square feet. Listed below you’ll find some of the major heater styles as well as information on their characteristics.
- Fan Forced
Fan forced heaters utilize a fan to move air past a heated electrical element. As the air moves past the element it becomes heated before moving out into the room. Fan forced heaters provide soft, comfortable, and gradual heating and are well suited to smaller rooms which do not need to be heated immediately after the heater is switched on.
Ceramic heaters replace the electrical element in fan forced heaters with a ceramic heating element to provide more heat while using the same principles. As such, ceramic heaters are suited to heating larger rooms. They also have a greater ability to focus the heat being produced than do their fan forced counterparts.
Quartz heaters utilize infrared radiation to provide greater heat which is often compared to that of the sun. They are very useful for heating people and objects but less so for heating air as the infrared heat produced is of a different spectrum than the absorption spectrum of air. Quartz heaters use metal reflector sheets to direct the heat in the direction it is needed and are well suited to heating larger rooms as well as outdoor spaces.
- Propane/Natural Gas
Propane and natural gas fuelled heaters work on the principle of an extremely controlled flame within the unit heating the air inside before a fan pushes the heated air out into the room. These are the most common kinds of heaters found in industrial applications and can produce large quantities of heat for extended periods of time. Residential applications often value electrically generated heat over propane or natural gas because of the simplicity of plugging the unit into a wall over refilling and fuelling with compressed gas.
- Free Standing or Wall Mounted
The question of free standing or wall mounted heaters essentially comes down to your own application and personal preferences. Free standing heaters can be moved around a space which is useful if you need to direct heat to a few different locations. They can, however, provide a tripping hazard when sitting on the floor which is not ideal if you will be moving around your garage or workspace a lot. Wall mounted heaters remove the tripping hazard as they are not typically in an area that you would find yourself moving about in. The downside to this is the fact that they are difficult to move once they have been installed and therefore cannot be transferred as needs be. One upside of mounting propane or natural gas fuelled heaters on a wall is the fact that you are able to isolate all of the necessary piping and fuel bottles away from walkways. If your heater is mounted on an exterior wall it is also easier to run piping for venting to outside your workshop.
Safety Features to Look For
Modern garage heaters come with a wide variety of safety features to ensure that nothing bad comes from having an extremely hot object inside the walls of your house or workshop. A major safety feature to look out for would be overheating protection. This system will detect if the heater is producing too much heat and therefore becoming unsafe, stepping in to switch it off before any damage is done to your home or the heater itself.
Another extremely useful safety precaution is tip-over protection. Imagine your heater gets inadvertently knocked over and is laying face-down on the floor. This is bad enough in a garage but could be disastrous on a carpet inside a house. Sensors inside the heater will detect when the unit has been knocked over and shut it off immediately so as to minimize the risk of a fire starting.
Safety Precautions when Using a Garage Heater
Garage heaters are, by their very nature, capable of generating intense quantities of heat. Even electric heaters, which lack the controlled but active flame of propane/gas burning heaters, can start fires and have other adverse effects if used improperly. There are a few things to consider when using a garage heater in a safe manner.
Firstly, you should always make sure that any gas bottles or fuel sources are kept well away from your heater. Fuel sources can include oils, aerosols, gasoline/diesel storage containers, firewood, and any other flammable material. If possible you should keep substances that can add fuel to a fire are kept in a separate storage area, be that a different room from the one being heated or a specifically designed fireproof cabinet.
Second, you should try to keep your garage heater out of the path of foot traffic and other movements. This may mean mounting the heater on a wall/ceiling or simply finding a place for it that’s well out of the way. Avoiding the possibility of the heater being knocked over should be of high priority. Although modern garage heaters feature safety systems that will shut the heater off if it gets knocked over it’s always better to be safe than sorry when dealing with fire risks and ignition sources.
Third, you should make sure that your new heater is in good condition when it arrives and that you frequently check on it to make sure that it hasn’t become damaged without your knowledge. As you might imagine, the manufacturers of garage heaters want their operation to be as safe as possible and they will happily replace the faulty unit if it arrives with damaged components. If you have an electric heater you should make sure that the power cord is not frayed and is in good condition. Gas fuelled heaters should have their burner nozzles inspected to make sure they’re functioning as they were designed to do. If you are not comfortable performing these inspections yourself you can always take your heater to someone who is certified in their maintenance.
With any kind of heater, you should make sure that the motors/fans are free of dust and debris and that you keep any accessible areas of the heater clean. Dust and lint can prove extremely flammable and making sure they don’t build up on your heater can save you from an unnecessary fire.
Finally, any gas fuelled heater will require exhaust venting. Make sure that the exhaust piping ends up outside the building in the fresh air and that it isn’t being expelled near any windows or HVAC intakes. When used correctly and given their proper respect garage heaters are an excellent way to keep warm and keep working through the cold winter months.
