How many units do I need?
When determining the number of units you will need, take into consideration:
•
The insulation factor, and window size & placement
•
The mean outside temperature during the coldest days of the year
•
The size of each room
• The overall size of the home
• The number of floors involved
•
The entrance and egress points
In lieu of overall engineering calculations and thermal loss calculations, a general rule
of thumb can be applied to determine the number of units you will need if using the
in-wall unit as a primary heating source:
New construction (coldest day above 5 degrees), standard insulation, one
window per room:
Room size up to 500 sq. feet: 1 unit
Room size above 500 to 1000 sq. feet: 2 units
New construction (coldest day below 5 degrees) & all remodels, standard
insulation:
Room size up to 350 sq. feet: 1 unit
Room size above 350 to 700 sq. feet: 2 units
Hallways and Nooks: 1 unit per 400 sq. feet
Closets and Bathrooms: 1 unit per 400 sq. feet
