Keep Your Garage Warm and Comfortable with a Unit Heater
A high-quality garage heater ensures you stay warm and comfortable while working, all while maintaining clean, breathable air. Gas unit heaters draw combustion air from outside, preventing dust, dirt, and humidity from affecting your workspace.
Whether you need a powerful 125,000 BTU heater or a compact 30,000 BTU model, these units offer premium features like whisper-quiet operation, finger-proof fan guards, and factory-added lubricants to minimize wear and extend product life.
Choosing the Right Garage Heater
Garages typically have less insulation than homes and frequently allow cold air in through doors that open and close often. As a result, selecting a heater with sufficient BTUs is essential to maintaining consistent warmth. When purchasing, you’ll also need to choose between a natural gas or propane unit, depending on your fuel preference.
Built for Durability and Performance
While often labeled as residential, these unit heaters are built to commercial-grade standards—offering reliability and longevity. A standout choice is the Modine Hot Dawg series, known for its compact, low-profile design. These heaters mount just one inch from the ceiling, keeping your space open and clutter-free. Installation is straightforward—simply attach the brackets, secure them in place, plug in the power cord, and connect the vent for gas service.
Why Choose the Hot Dawg Series?
- Aluminized-steel heat exchanger reduces runtime, minimizing motor wear.
- Zero-maintenance, self-lubricating motor for quiet and efficient operation.
- Power venting system clears exhaust air, ensuring clean air quality.
- Flexible venting options—install through a side wall or roof vent.
- Built to last—maintains its sleek appearance even after years of use.
- Industry-leading warranty—10 years on the heat exchanger, 2 years on other components.
