I'm in the final stages of refinishing my basement. I'm trying to determine how much baseboard I need for the room. I think I should be using a mulipler of 25-35 BTUs per sqft but not too sure.
The finished space is 450 sqft. I installed 2" thick foam boards on 2 outside walls, the other two walls are adjacent to unfinshed areas in the basement. All walls are insulated with R11 fiberglass. I have 3 (1x3) double pane windows. I plan on running 'Slantfin 15' with a 580 BTU/ft rating.
At 25 BTUs per sqft - 20' baseboard
At 35 BTUs per sqft - 27' baseboard
What do you suggest? I know I need to do a heat loss calc but too confusing . I'm curious to hear what others did.
Rule of thumb is 30 BTU's per square foot, to be on the safe side and cost down the road due to insulation breakdown. Spend the extra for the 27 inch.
Hope it helps, windows also play a role as heat loss and position. You will be on the safe side to go with the 27 inch.
