Garage Heaters

Modine’s wildly popular Hot Dawg line of garage heaters take the job of heating spaces seriously. With no-maintenance electric motors, easy installation, and dependability that lasts for years, the Hot Dawg series ensures that with this line of gas heater, comfort just went up a few notches.

Modine’s Hot Dawg line includes BTU capacities ranging from 30,000 BTUs to a whopping 100,000 BTUs, yet all this performance is housed in lightweight cabinets that mount out of the way, up near the ceiling. They are available in natural gas or propane and come with a 10-year warranty on their heat exchanger and two years on everything else.

Hook-ups to electric service and ventilation are easy, and the noise level is amazingly low.
