One thing worth knowing if you are weighing gas tankless against a tank: most residential gas tankless units are rated above 75,000 BTU/hr, which puts them under the 2031 compliance date rather than the 2027 one. How the zero-NOx rule applies to tankless explains which date covers your unit and how to check the nameplate.
