What is the best way to heat a big open floor? Ductless units or a radiant baseboard unit?

Asked by B Stewart

Keep in mind we have a large stairwell that acts as a chimney. I am unable to redo the whole HVAC in the house. This will be an additional unit that will heat the main floor since the original HVAC and air handler is on the roof and the heat does not reach the main floor. It is terribly inefficient.

Generic answer: it depends on your fuel -- if you are all electric, a forced-air mini split will be better than electric resistance baseboard, which is the least efficient system you can get.

Best advice: get an energy audit to determine the true reason why the main floor is cold. Are there insulation issues, air sealing issues, HVAC duct issues? Once you pinpoint the cause, you can get a customized solution.

If you are serious about fixing your house, and making it more efficient, spend $400 or $500 on an energy audit. It'll save you thousands of dollars by not assuming a solution and installing the wrong thing. A list of independent auditors in the DC area can be found at www.mdhomeperformance.org.
