underground bunker heater


DEFCON Underground Mfg., installs high quality ventless propane wall furnaces for your underground bunker. These furnaces are almost 100% efficient and approx 30k btu.

Our vent-free gas heaters offer convenient, easy to operate controls on the top of the unit. The push button igniter lights the pilot, eliminating the need for matches. Each unit is test fired in the factory and contains an oxygen depletion sensor that shuts off the unit if not enough fresh air is available. Our heaters use a state of the art powder coat process that produces a durable, scratch resistant finish.

Of all heating sources available, gas heats an area for less than half the cost of electricity.

flooring for underground bunkers


DEFCON can also install high quality flooring to give your shelter a more home-like feel. Traditional wood floors can expand and contract with humidity leaving gaps, but High Pressure Laminate (HPL) is rated best for high humidity, therefore perfect for underground shelters. The special glues used in HPL ensure that your flooring will look nice and function properly for years to come.

Multiple customizable underground bunker floor plans to meet your security needs.
