We’re being forced to. After 2030 no more gas water heaters or furnaces can be sold. The cost of heating your house and water here is going to probably triple or more, and will fail every time there’s a blackout.
You used to be able to buy water heaters that would last forever. My house had one from the 1950's with a copper tank. Still going strong. Just don't be convinced b y the repair man to get a new one when you have to replace the thermocouple every 8 years or so. The furnace is from the late 1980's, still fine.
I'm not sure if such well made devices are still available for purchase however.
