Questions & Answers

Ask a Question
  • What percent efficient is this unit. Does it have a separate combustion chamber and hot air chamber with a blower.

    The manufacturer does not have an efficiency rating for this model  It does not have a separate combustion chamber or blower.  The Fortress is designed as a decorative appliance and while it does produce heat, it is not intended for use as a primary heat source. Thanks for your question!

  • Can this unit be used between interior and exterior which is an all season sunroom, or is there a a different style of fireplace see through fireplace I should look at.

    This could definitely work for that situation.  This type of fireplace is designed for indoor/outdoor use so one side is fully sealed to prevent exterior air penetration.  So if you're sunroom is not fully part of the interior building envelope, you would want this type of fireplace.  If your sunroom is part of the interior envelope, then you could opt for an indoor/indoor fireplace option if you prefer.  Thanks for your question!
