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.<u></u><u></u></div><div><div><div style="margin:0in;font-size:11pt;font-family:Calibri,sans-serif"><br><br><u></u><u></u></div><blockquote style="margin-top:5pt;margin-bottom:5pt"><div><div style="margin:0in;font-size:11pt;font-family:Calibri,sans-serif">On Nov 8, 2021, at 11:05 AM, Pat Horne <<a href="mailto:patintexas@icloud.com" style="color:blue;text-decoration:underline" target="_blank">patintexas@icloud.com</a>> wrote:<u></u><u></u></div></div><div style="margin:0in;font-size:11pt;font-family:Calibri,sans-serif"><u></u> <u></u></div><div><div style="margin:0in;font-size:11pt;font-family:Calibri,sans-serif"><span style="font-size:10.5pt;font-family:Helvetica,sans-serif">Jim, you hit on most of what I was thinking.
