Basement very cold what can I do
I have a new home that is well build and very well insulated…very low gas heating bill for size of house. I have two furnaces one on the upper and main floor. The main floor thermostat serves both the main floor and basement. House is very well built and uses very little energy. The problem is the basement is 10 degrees colder than the main floor. Usually 58 to 60 degrees. It is fairly large basement; finished, carpet and air vents in the ceiling. The return vents are in the ceiling and are at the back of the basement. No basement door. Any ideas on what I can do to warm up the basement. No one wants to use it. I do have two space heaters but would probably need 5 or more to warm it up. Would adding a door help. I’m open to adding more heating. Note I am putting in solar panels this year. Appreciate any advice. Thank you.
