Well,let me start by saying you all rock.I have picked alot of good help here.My situation is that my older eshland indoor boiler smokes in many ways.First was out the door when loading and a smoke hood has resolved that.Second is that when loaded with alot of wood it pulses air until fire stabilizes after about 1 hour.Now when pulsing smoke puffs out all seams on flu pipes and from seams on 90 degree pipes.Small amounts of smoke but the smell goes right upstairs.The unit holds about 40 gallons of water and is hooked up to a buderus condensing boiler which has no water storage so all water is from the wod stove.My house is 1400 sq ft. older drafty house.The wood stove does idle alot and today my chimney (8 inch)plugged up.I clean chimney about every 4 to 5 weeks.So i am considering if possible to install this stove outside in an insulated shed or make a housing for it and run insulated lines into the house and hook up to a storage tank?What do you think?Also if so what size expansion tank is needed for a larger storage tank say 100 gallons or so as my system is pressurized and direct to buderus.The way i am hooked up is pump runs continous loop from wb to buderus return manifold and back to stove.I have a normally open zone valve between feed and return so water makes complete loop when no heat is called for.When buderus calls for heat and heating zone valve opens and pump turns on the normally open valve between closes causing wb water to head thru buderus thru baseboards back to wb and continue on.Works goodI just turn down buderus temp to below wb setting and buderus does not fire.My chimney is just afew years old and always worked great with other wood stoves.My wife deals with this problem ok but cannot stand the smell and it has gotten the best of me to.thanks in advance.I can add pic of hook up if needed.
