Pool heaters are rare as hens teeth! Good score!

I've been scrapping actively, putting 800-ish miles a week on a truck through residential hoods where people with more dollars than sense reside... and I've only gotten 4 or 5 in 10 years.

It's a matter of people that need it done won't do it themselves, so they hire it done & the installer probably even charges for hauloff of the old one, and recycles it themselves.
