We just got done with a very cold winter.
On some of the coldest days there was a lot of condensation in the house right near the ceiling adjacent to the chimney.
I have a standard gas furnace that's about 22 years old and there is NO liner in the chimney. Various chimney repair companies have told me I should get a liner installed to avoid condensation.
I was about to do so then realized that I'll probably need a new furnace within the next few years anyway and now might be the time to not only get a high efficiency furnace but to get central air instead.
The 100 amp service in my 116 year old house is maxed out so I have hired a contractor to upgrade the service to 200 amps.
Now, my question: I still have a gas hot water heater using that chimney which will be otherwise unused. Is it likely I'll still get condensation on cold winter days?
