Is it possible to vent an 80% efficient boiler directly outside without going through a chimney?
About 6-7 years ago I had a brand new boiler installed to replace the nearly 100 year old original boiler. The contractor told me they could use the existing chimney for the boiler and the hot water tank. All appeared to be fine for the first 2-3 years, but in about year 4 the chimney in the attic started to appear to deteriorate from the inside. The chimney is partially inside and partially outside of the house, which is 3 stories tall. The deterioration is in the form of the paint and plaster covering the brick is damp and pealing. When I bough the house the chimney was fine and has progressively gotten worse since I noticed in 3 years ago.
I would like to know if there is anyway I could pull the vent pipe out of my chimney and run it directly outside. The boiler sits near an outside wall so the length of pipe it would need to travel to get outside would be 8-10 feet.
Thanks for any help.
