    Basement is 100% finished. Have no idea if there is a vapor barrier between the ground and concrete, but I would suspect NOT since that was probably not code back in 1972 when the house was built. ...

  9. Interesting Dehumidifier Question for Whole House

    I have a properly installed GREENSPEED system which is able to pull down the humidity in the house to ~ 52% in Summer. Not bad, but I'd like to get it 10 points less - to ~ 42%-45% max (or whatever...

    TB, what is the cost to operate a "typical" dehumidifier year-round? Are they designed for 24x7x365 operation, or is there a brand which is built more rugged than the others for this type of purpose?

    Will the new system also come with a new stat to go along with it, or will it reuse the current Infinity stat?
