If I can, I will persuade them to just bite the bullet and replace it. Truth be told, it is really the boyfriend’s house and he has spent a small fortune on things that show, like the kitchen and bathrooms, but been more stingy with something like this that he can’t see.

You are correct that a replacement is unavailable. The furnace is just too old. As for having it welded, I should add that my brother-in-law - who lives nearby and is an engineer with tons of local trade contacts - looked at it and concluded that trying to remove it for welding was not a good option. Surprisingly, he did not tell her to replace the system immediately, which was surprising as he is someone who generally errs on the side of caution in matters like this. It has been a while since he looked at it (they have owned if for a year but not lived in it do to other extensive renovations) but I will also call him to discuss it.<o:p class=""></o:p></div><div class=""><div class=""><div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><br class=""><br class=""><o:p class=""></o:p></div><blockquote style="margin-top: 5pt; margin-bottom: 5pt;" class=""><div class=""><div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class="">On Nov 8, 2021, at 11:05 AM, Pat Horne <<a href="mailto:patintexas@icloud.com" style="color: blue; text-decoration: underline;" class="">patintexas@icloud.com</a>> wrote:<o:p class=""></o:p></div></div><div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div class=""><div style="margin: 0in; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 10.5pt; font-family: Helvetica, sans-serif;" class="">Jim, you hit on most of what I was thinking.

She has a CO2 detector in the basement, but I will be visiting her next week and want to try to do more. “More” might be trying to convince them to bite the bullet and replace the system immediately, but I have also thought about treating it like an automotive exhaust system and trying to patch it to get them by for a season or two.
