new oil furnace - new water problem

ejoseph Member Posts: 1
Hi & thank you for reading. Owned house about 30 yrs and never a problem. Added a new oil furnace. Since then have water leaking in to basement thru clean out door. Have white efflorescence stain on outside house on chimney. Installer says water is condensation caused by exhausted air (383 degrees) cooling before discharging chimney, turning to condensation/water and dripping back.
thoughts, suggestion is my installer taking me down the wrong path ?
THANK YOU !!!!!!!!!!!! Ed in Massachusetts

    Is this an exterior chimney or is it all interior?

    Did they install a chimney liner? Is this an exposed or interior chimney? Did they check the boiler/furnace BTU versus the size of the chimney

    Shouldn't the installer be fixing it if they put in a new furnace without a liner and it needed a liner to draft properly...

    Sounds like you need a liner, possibly an insulated liner especially if the chimney is exposed to the cold for more than a few feet.
