ITD,
To answer your question regarding removing and replacing the coil, it's sort of a crap shoot ! By that I mean if the bolts on the plate housing the coil are rusted, they could snap off, then the bolts would have to re-tapped, running up the cost. The coil costs about $450, with maybe 2-3 hours work depending on unforeseen issues during replacement, and no guaranty it won't leak at that connection after work completed. So bottom line, about $700-800, and I still have a 25 yr old boiler..... I could be throwing good money to bad on this option, a roll of the dice ! A lot of "if's" to replacing coil !

So difference between coil replacement and new boiler about $4000-4500, still a lot of money, but I'll be able to sleep at night, and know I have hot water for another 25 yrs., but I'll be dead by then !

Yes, I hear you on that. I suppose if money is not an issue then go for it. If money is an issue I would try cleaning the coil and probably replacing the mixing valve. No matter what you choose I hope it works out for you.
