Uncle Mud Rocket Heater--Are Your Chimneys Competing for Draft?

A tightly sealed house with multiple chimneys can create a situation where the woodstove and the gas or propane water heater and furnace and clothes dryer are all competing with each other for the little bit of air that gets in through the cracks around the windows and doors. This can cause those appliances to draft poorly or even leak CO and CO2 into the house. I strongly recommend that each device has its own properly sized outside air source so the air in the house is mostly for breathing by people. Also get yourself a CO detector.
In this case we determined that there was plenty of air getting into the house but the missing door on the cleanout at the bottom of this chimney was using up a good chunk of the tiny amount of draft this massive cold chimney produces. We're going to fix that by closing off the cleanout and continuing to remove obstructions in the chimney.

Is it possible to tie a RMH to an existing, reinforced chimney?

Yes but you will need to plan to let more heat out of the system to warm up the chimney sufficiently for it to have a reliable draft. It will work better and be more efficient if you line that concrete chimney with an insulated stainless steel flexpipe liner
