These garage heaters also ensure that while you’re working in your garage, you have plenty of high-quality air to breathe. Gas unit heaters draw their combustion air from the outside to ensure the air around you is clean. This supply of fresh air reduces common concerns about dirt, dust and humidity.

Additionally, whether it be 125,000 BTUs or a 30,000 BTU garage heater, you will enjoy such amenities as whisper-quiet operation, finger-proof fan guards, and a long-lasting lubricant, added at the factory, which is designed to reduce wear-and-tear and prolong product life.

When sizing for a garage heater, keep in mind that your garage will not be as well insulated as the rest of your house, plus it will have places where air escapes easily. The garage door(s) will be opening and closing frequently, allowing cold outside air to rush in. Therefore, you will need a unit with greater BTUs than you would for a typical space.

When ordering you will need to choose between a natural gas or propane garage heater.

These unit heaters are often marketed as residential heaters, but they have the durability and performance that puts them in the same league as commercial heaters.

A standout in this category is the Modine Hot Dawg garage heater series. They’re simply designed, have a low profile and install as close as one inch from the ceiling. They are lightweight and easy to lift into position – out of the way of anything else in the garage. Attach two brackets, tighten securely, plug in the power cord, connect the small diameter power vent and the unit is ready for gas service

One of the more impressive features of the Hot Dawg series is the aluminized-steel heat exchanger, which reduces run time and therefore eases wear and tear on the motor. The motor is zero maintenance, self-lubricating, and quiet-running. All of the Hot Dawg line, including its popular 45,000 BTU garage heater model, employ powered venting to clear out exhaust air and maintain air quality in the garage. They can vent to side wall vents or roof vents with ease. These units are built to last and to look brand new even after years of service. The warranty is 10 years on the heat exchanger, two years on everything else.
