    Hydrotherm Celtic and a 15-42

    Anyone out there on Wally World have an older but still operable Grundfos 15-42? Say from the mid to late 80's? I have a customer here in NH that has a Hydrotherm Celtic 50k input, that still works perfectly fine. Mfg date 3/1984. Some other contractor decided to replace the circulator. Instead of searching for the right one he installed a 26-99 in the frame that is built into the boiler...a newer 15-58/42 is too small. Now they are having air issues because the 26-99 is way oversized.

    Ya I saw that one...

    I cant see replacing a boiler in such a small space, that does not cost a good deal to run and runs fine. Sort of like ditching a car because it needs 4 new tires.

    Have you tried

    calling Grundfos to see if they still have parts?  Someone here ought to have a "clueful" contact on the inside.

    Pix. It's still in great shape. And is around 82%. It's 50k input. 41k out. The food has only heatloss front and back. None to the sides.

    Will the 15-60

    I don't know what the pump curves are for the old 15-42 but this seems to be a Celtic replacement (I certainly wouldn't buy it from Europe :)  ?

    If I cant find one soon I am going to see if I can go in a find a way to adapt over the piping that is there and see if I can add a new circ outside of the cabinet.
