I took my lines off EVERYWHERE. I started with the lines coming into my first exchanger (cold from the house water line, hot from the stove, out to the hot water heater, out to my furnace) The heat exchanger was completely plugged up with calcium chunks. I cleaned those out and then took off the lines to my plenum above my furnace. When I do so, I poured out the lines into a pitcher. It was full of calcium crap. I decided to try cleaning out my plenum/radiator looking exchanger. I blew into one end and it sounded like the thing was vomiting chunks of calcium out everywhere.
I did not have the crimping tool to crimp my pex lines back onto my furnace, but will do so tonight.
I may go ahead and replace my pump as well while I am at it. I can get a new pump for $78 so why not.
I have a nice water softener unit that I constantly forget to fill up with salt. After all of this trouble, I will NOT be forgetting to do so in the future. Dealers that install these things should give a heads up to people that purchase a new stove by telling them about stuff like this. I'm sure I am not the first guy this has happened to. I feel like I could install these things now because I have done nearly everything there is to do.
I'm going to order another pump and run pex line out to my garage/barn, install a hydronic heater with a thermostat so I can keep it heated out there whenever I want to now that I know what all I need to do.
I will let everyone know for sure what ALL I had to do once I have wat water and heat again from my stove rather than my electric heat pump and my electric water heater which KILL me financially to run in this frigid sub teen cold weather.
