So You're Getting a Garage Heater

While for many people a garage is nothing more than a seldom-visited repository for old cans of paint and spare rolls of paper towels, others treat the garage like a valued part of their homes. This can be so simply because it is regularly used as the protective parking spot for a vehicle or because it is the site of frequent mechanical tinkering, workout sessions, discussions about sports, and so forth.

If your garage is treated as the latter, ostensibly serving as yet another room in your home, then you are likely acutely aware that few garages are nearly as warm and welcoming as the other rooms in the residence. Even a fully insulated garage will still grow quite cold during the winter if it does not enjoy a dedicated source of heat -- insulation can slow the loss of heat when the ambient temperature is cold, but it cannot provide any warmth and is rarely effective enough to utilize the bit of heat passed through walls touching the home.

Simply put, if you want a garage that is not going to be freezing cold inside when the weather is freezing cold outside, you will need to get a garage heater. Choosing which heater will best serve your garage (or your other similar space, as the same unit can be used for most freestanding workshops, sheds, steel buildings, barns, and so forth) is not a complicated process, but it can represent a large investment, so it merits careful deliberation nonetheless.

No garage heater will ever be purchased for its aesthetics. These are objectively unsightly devices not suited for a space designed to please the eye, but rather purpose-built to warm up an area intended for safe storage of vehicles, tools, and sundries and often used for hands-on work at repairs or hobbies, for physical exercise, or for any project too messy or odorous for completion inside the home.

In fact, there are really only three primary considerations that will inform your process of choosing a garage heater. These are interior area, energy source, and heater price.

As the size of your garage (or workshop) is the factor over which you have the least control, it merits primary discussion. To fully heat a spacious two- or three-car garage, you will need a heater that can produce approximately 45,000 BTUs of heat per hour. If you try to save money by buying a smaller unit that cannot properly heat the space, you will end up dealing with a chill even while using the heater and/or ultimately spending more money anyway as the device will have to run for much longer to compensate for its lack of power. For a smaller space, such as a narrow single-car garage, a heater producing between 10,000 and 20,000 BTUs should suffice.

As for energy source, many garage heaters burn propane or natural gas to produce heat while others are powered by electricity. Consider the type of wiring already present in the space you need to warm, as some heaters may require an outlet with voltage your home can't currently provide. Some smaller heaters use bottled propane while others connect to a hard-lined source of natural gas. There is no right or wrong way to create heat, merely the most logical fit for your household.

A Few Words On Garage Heater Safety

When properly installed and operated according to their instructions, garage heaters are safe and reliable units. Many come with impressive multi-year warranties which serve as a testament to their reliability.

But the cautious person will still take a few extra steps to ensure their home remains safe even once they are comfortable with their new garage heater. The simplest way to make sure the heating unit never presents a danger to the residence is simply to never use the heater when you are not home. If you will be away from home for an extended period of time, consider not only turning the heater off, but also unplugging it completely.

The standard garage tends to house a number of flammable and/or combustible materials. These include everything from pressurized cans of paints, tins filled with solvents, bottles of motor oil, gasoline in a container or in the tank of a vehicle, and much more as well. When properly stored, these inherently volatile compounds are perfectly safe, but as adding a heater to a space also adds a heightened potential for sparks or enough heat to generate a flame, it's important that you carefully re-consider how and what you keep in your garage before you choose to add a warming element.

Take the time to rearrange your storage space, moving flammable and/or combustible materials as far from the heater as possible. Also take the time to check the exhaust vents and air intakes of your heater on occasion, making sure airflow is not restricted to or from the unit.

A Few Fine Garage Updates

If you have installed a heater in your garage, workshop, barn, or other space, the next item you should procure and install is a smoke alarm. Ideally you will choose a unit that also detects carbon monoxide. Install this vital piece of safety equipment on a ceiling near the heater but not directly in the path of the hot air it produces, as this may lead to false alarms as the detector encounters dust or bits of particulate matter stirred up into the air.

Adding weather stripping around the door of your garage can keep out cold air and moisture, helping you to maintain a warmer, cleaner interior at minimal cost and with relatively easy installation. These strips of rubber usually secure to the ground and frame of the garage with a built-in adhesive or else using epoxy resin or another glue. Weather stripping is a wise idea especially in older garages where the seal between the door and frame is lacking.

And as you want your garage to be a welcoming place ideal for work, recreation, or exercise, make sure that it is a well-lighted space. LED tube lighting costs relatively little and is highly energy-efficient but adds more than enough brightness for work under the hood of your car or for a game of darts with the guys.
