Model HDS Hot Dawg® Separated Heater Combustion Units are a convenient and affordable way to keep your greenhouse plants warm for winter growing. The separated combustion Hot Dawg draws its combustion air from outside to ensure that the unit always has plenty of fresh, clean air to breathe. 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.

Advantages of Hot Dawg Space Heaters

The Hot Dawg® by Modine is designed to generate heat without the expense or hassle of a regular HVAC setup. You don't even need electricity! Here are some of the ways these heaters outperform other units:

• 100% outside air for combustion
• Sealed compartment protects combination gas control
• Ignition control
• Manifold and burner
• Horizontal or vertical concentric venting
• 80% thermal efficiency
• Field convertible to propane
• 100% shutoff with continuous retry

In addition to greenhouses, the Hot Dawg is also an excellent combustion garage heater, It's available as an indoor propane heater, natural gas heater or LP (liquid petroleum) heater with a 10-year warranty.

Install a Modine Hot Dawg separated combustion heater to keep plants, vehicles, equipment and people warm during the winter. Also known as a sealed combustion heater, these units have a design that uses outside air for the combustion process with a secondary exhaust vent. This makes the heater more efficient and prevents damage from indoor air contaminants. It also stops dangerous gas exhaust products from entering the air you and your plants breathe. No electricity is needed, letting you install the heater wherever you have the appropriate venting.

Greenhouse Megastore has a variety of Modine combustion space heater models that burn at 80% efficiency. Maximum hourly output ranges from 24,000 BTUs (single-car garage and small greenhouses) to 100,000 BTUs (any open structure up to 1,200 square feet). You can order a natural gas, liquid petroleum or propane heater that is ultra-quiet. The heat exchanger has a full 10-year warranty, so you can count on its operation for any growing or living space.
