Supporter
$20 · A Line in the Ledger

Waterheaterhistory.com is a free, independent educational resource. People come here for a sourced account of water heating — the history, and the technology still in use. The site is not a store and not a ranking list. It is a living reference built from patents, catalogs, engineering literature, museum collections, and machines documented in the field.

​

A Supporter helps keep those pages public with a gift of $20. Recognition is optional. You may be listed by name or as Anonymous. If you choose to be named, it appears on this page as one line in the record — not an advertisement, and not an endorsement of any product or service.

This page is only for Supporters. The $20 package below is what this program provides: a one-year listing, renewable, with the option to upload historic water-heater material at no extra cost.
