Household size in, correctly sized unit and installed cost out — tank or tankless, gas or electric. Then send it straight into a quote.
Ballpark, not gospel. Sizing depends on peak demand and local code — verify gas line capacity and venting requirements before quoting tankless.
Straight answers, no fluff. Then run your own numbers above.
Rule of thumb: 1–2 people → 30–40 gallons, 3–4 people → 40–50 gallons, 5+ people → 50–75 gallons. What really matters is the first-hour rating — it should cover your peak simultaneous use (showers + dishwasher + laundry).
Tank water heaters run $1,100–$1,500 installed in 2026 ($500–$700 unit + ~$600 install). Tankless runs $3,500–$4,500+ installed — pricier upfront, cheaper to run.
Tanks win on upfront cost and simplicity. Tankless wins on endless hot water and efficiency, but needs gas line or electrical upgrades that add $500–$2,000. Quote both when the panel or gas line allows it.
Tank heaters: 8–12 years. Tankless: 15–20+ years with annual descaling. If the unit is over 10 years old and the quote is for a repair, price the replacement too — most clients choose it.
