"Some woman who saw my ad on a dating site, and saw that I was interested in heat
pumps contacted me and offered to give me her no-longer-working heat pump for free."
The exact thing that I'd expect to cause absolutely nobody to contact you.
"...When I declined her generous offer (in her case, declining the offer was pretty easy)"
Sounds like one of a kind, lol.
Nice score on the heat pump, just don't let it leave nasty uncleanable drippings on your mattress that'll make you wish you never picked her up.
