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
Typical timeline: About 2 weeks

Note: the federal 25C tax credit for HPWHs expired December 31, 2025 — state and utility rebates may still apply.
Estimated fee: $100 – $400

This is significantly more complex than a same-location replacement and typically costs $1,500-$3,500 in additional plumber labor.
Estimated fee: $150 – $500
