Q: What is a Hot Dawg?
A: It's a low-profile gas-fired unit heater that is designed to heat your work space. It is certified for residential, commercial, and industrial use.
Q: Where can a Hot Dawg be used ?
A: The Hot Dawg was designed to provide heat to places where it normally wasn't found, particularly garages and woodworking shops. With a Hot Dawg installed in your garage, you can now work in a safe, heated environment. Whether you are simply taking your kids in and out of the car, leaving for work in the morning, or working on your hobbies, the Hot Dawg makes the garage usable 24/7, 365 days a year. See the attached brochure (Retrieve a Brochure) for more examples.
Q: Where does the Hot Dawg get its combustion air?
A: The Hot Dawg draws air from within the space being heated (power exhausted, HD model) or from fresh, outside air (separated combustion, HDS model).
Q: Why should I choose the separated combustion model rather than the power exhausted unit?
A: The separated combustion unit requires less maintenance in dusty environments, improves seasonal efficiency, provides greater durability in hostile applications, and has external thermostat and gas connections. This unit is especially popular in woodworking shops where wood particles float throughout the air.
Q: Can I control the temperature in the space with a Hot Dawg?
A: Yes, the Hot Dawg unit heaters work with a standard or programmable thermostat similar to the one you would find in your home.
Q: What type of fuel feeds the Hot Dawg ?
A: The Hot Dawg can operate on either natural or propane gas. The gas type must be specified when ordering.
Q: Does the Hot Dawg vent to the outside of the garage?
A: Yes, it is supplied with a factory-installed venting system that allows for either vertical venting through the roof or horizontal venting through a side wall. Vent pipe must be purchased separately and installation should be performed by a licensed contractor.
Q: What size Hot Dawg is needed to heat my work space?
