Frequently Asked Questions
How much does it cost to replace a water heater?
Water heater replacement typically costs $550–$1,300 for a standard gas or electric tank unit, including labor. Tankless units run $700–$4,000 installed. Heat pump water heaters cost $1,100–$4,300 but qualify for a 30% federal tax credit (up to $600).

How long does water heater installation take?
Standard tank water heater installation takes 2–3 hours. Tankless installations take 3–5 hours. Heat pump water heaters may require additional time if electrical panel upgrades are needed.
What size water heater do I need?
For a household of 1–2 people, a 30–40 gallon tank is sufficient. 3–4 people typically need 50 gallons. Households of 5+ need 75–80 gallons or a large tankless unit. A licensed plumber can recommend the right size for your usage.
