Converting from a tank to a tankless gas water heater requires plumbing AND gas permits. Tankless units demand 150,000-199,000 BTU/hr at full capacity — about 4-5x a tank unit's demand. Existing gas lines are typically undersized and must be upgraded. New direct-vent or power-vent systems are required; existing B-vent cannot be reused.
Estimated fee: $100 – $500
