We're in the midst of a basement renovation and one of the huge problems with this basement (since we bought the house, anyway) has always been that it's about 5-7 degrees colder than the rest of the house. The ducts are being re-routed, more return air from the main floor is being added, and hopefully our entire HVAC system will run more efficiently when all is said and done.
However, our HVAC expert thinks that all this work will probably only get us a basement that's STILL 3-4 degrees colder than the rest of the house. He suggests putting radiant heat in the perimeter of the house to supplement our regular forced air heat system.
Does this make sense? Why only have the radiant heat on the perimeter (other than cost)? Will that be a problem?
