Our money stat
$/MMBtu — the cost of a million BTU of heat

- No star ratings, no opinion scores. Verifiable facts and transparent computed metrics only.
- No invented specs. Every efficiency and capacity number traces to AHRI or ENERGY STAR. Missing means "not published" — never a guess.
- No paid placement. Rankings are the data, sorted. You can re-sort them yourself.
