Hot Dawg® Model HDS
separated-combustion, gas-fired unit heater.


The separated combustion Hot Dawg draws its combustion air from outside to ensure that the unit will always have plenty of fresh, clean air to breath. This fresh-air supply reduces common concerns about dusty, dirty or humid applications. In addition, by drawing the combustion air from the outside, the overall heating efficiency is increased. The Modine Heaters are designed for Overhead Mounting in Residential Garage applications or Greenhouse Heating applications.

In short, the Hot Dawg separated combustion unit gives you the added advantages of:

  • Less maintenance in dusty environments.
  • Improved efficiency by using outside air for combustion.
  • Greater durability in "hostile" environments
  • (Environments possessing substances that may deteriorate the performance of the unit).
  • External thermostat and gas connections.
