Hush-Puppy Quiet Operation & Compact Design

It also features a low-profile, lightweight design and can be mounted with a one inch clearance from the ceiling on only two angle brackets, keeping the unit heater out of your way.

Don't Get Caught in the Cold With a Cheap Heater

With a rugged aluminized steel heat exchanger, baked-on corrosion resistant polyester paint, and casing construction made of heavy guage metal, you can rely on the Hot Dawg to heat your garage or shop for years to come. This is all backed by a full 10-year warranty on the heat exchanger.

Low-Maintenance Upkeep and Efficient Heating Save You Time and Money

The motor on the Hot Dawg has a permanent, long-lasting lubricant straight from the factory. This means that the motor never has to be oiled, reducing maintenance costs, general wear and tear, and operational noise.

A power venting system on the unit quickly and efficiently brings flue exhaust from the unit heater to the outdoors, and requires minimal installation labor.

Electric wiring knockouts and field wiring connections on the heater keep installation costs low and save time during installation and maintenance by simplifying all required electrical work.

Frequently Asked Questions

can the Heater be connected to a thermostat?

Yes! Thermostats most commonly used with the Modine Hot Dawg Heater are single-stage room and two-stage room digital or duct thermostats. Additionally, low temperature thermostats are frequently paired with this heater. These thermostats can be set at lower temperature ranges than traditional residential room thermostats which typically have a range between 60°F to 80°F.

Is this unit set up to run on propane or natural gas?

The Hot Dawg runs on natural gas, but there is a conversion kit available from Modine which can convert it to propane.

Does the Heater vent to the outside of The Work space?

Yes! The venting system allows for vertical venting through the roof or horizontal venting through a wall. Please note that venting components must be purchased seperately and installed by a licensed professional.
