Unused Chimney question

Hey Everybody...

I am currently having a new high-efficiency furnace installed in my home in Chicago. With the new furnace, the exhaust is no longer going through my chimney block, but is going out the side of the house. My water heater still vents through the chimney, but I do not have a fireplace. I have a mortar chimney, and I've heard that mortar can begin to deteriorate over time if not enough heat (exhaust) runs through it with moisture freezing, expanding, etc.

Is this true, or something I need to worry about? Should I just look into have the chimney removed, or just wait to see if it begins to deteriorate and deal with it then?

Thanks all.

If that were true then the millions of homes that turn off thier furnace/boilers in the summer months would have bad chiminey. They are usually tile lined anyway and sized to acept the btus of your appliances. There may be slight draft issues if the chiminey was really oversized.

But if you are concerned you can have the chiminey lined with a 4"chiminey liner.
