Shelter Heating and Cooling

Steel shelters installed with 6 to 10 feet of dirt cover do not pose a heating and cooling issue. In the severe temperature variations (-20F to 100F) the interior of the shelters stay within a 20-degree temperature range (45F to 65F). In warmer areas, the air vents may require a deeper and longer horizontal run to cool the intake air before it enters the ventilation system.

We sometimes install a wood burning stove to heat the shelters during cold spells. These stoves cannot be used during threat time of nuclear fallout or war gasses, as the air to the stove is not filtered. We provide gas tight shut off valves for closure during those high threat times.
