So before I have my insert installed this Sat I had the chimney swept. While I was at it I had the chimney swept that exhausts the oil fired boiler and water heater. $30.00 bucks a piece.
The sweep said the fireplace flue was in good shape but the one supporting the oil burner is bad. The clay liner is going (he says bad bad) and mainly because there is no device to make sure both the boiler and water heater don't fire at the same time.
I can see the "volume" issue causing excess deposits but not so much how the simultaneous firing should hasten deterioration of the liner. The liner may very well be bad as the house was built in 62', but I'm hoping for a little insight. Does the deposition of soot "eat" the liner? I'm aware that Sulfer and Nitrogen to some extent can generate acids but anyone heard of this scenario?
His suggestion is to add a unit to prioritize one system over the other so they don't fire at the same time then install an SS liner. Wants $1000.00 to install and the liner he wants to use is very good. I've had my hands on it and it is heavy gauge (0.018" I think) and smooth so no problem there. Excepting a total failure allowing gases to reach the masonry what is the major issue, poor draft, anything else?
