Let me briefly explain thermal capacities of Heating, Ventilation,  and Air Conditioning (HVAC):


Normal operation

  1. Outside temperature is 20 degrees
  2. A normal house protects 10-30 degrees
  3. With out heating, the temperature of the house could be from 30-50 degrees
  4. Older heating units raise and maintain a 20-30 degree difference
  5. With heating, the inside temperature of this house could be from 50-80 degrees
  6. When it is 20 degrees outside, the Garden House can maintain an inside temperature of about 72 degrees


Now watch what happens!!!!



Extreme operation


  1. Outside temperature is (-12) degrees
  2. A normal house protects 10-30 degrees
  3. With out heating, the temperature of the house could be from (-2)-18 degrees
  4. Older heating units raise and maintain a 20-30 degree difference
  5. With heating, the inside temperature of this house could be from 18-48 degrees
  6. When it is (-12) degrees outside, the Garden House could be as cold as  45 degrees!


You can obviously see how such extreme weather affects our heating ability.   It is also recommend that during the winter, we make sure we have extra blankets and even a little $20 heater from Walmart.  Hopefully, this deep cold will pass in a few days.
