How much does water heater replacement cost?

Water heater replacement starts at $2,400 for a 40-gallon gas unit in lower cost-of-living markets and ranges up to $7,280 for a tankless gas system in high cost-of-living cities like New York and San Francisco. All WaterHeaterMan prices are fully installed — equipment, labor, and haul-away included.

How fast can you replace a water heater?

WaterHeaterMan offers same-day and next-day water heater installation in most major US metro areas. Our platform is available 24 hours a day, 365 days a year — book online in under 3 minutes.

Are your water heater technicians licensed?

Yes. Every WaterHeaterMan technician is state-licensed, carries $1M general liability insurance, and is factory-trained by the manufacturer of the specific unit being installed — Rheem, Bradford White, Navien, or A.O. Smith.

What is included in the installation price?

Every installation includes the water heater unit, all labor, disconnection and haul-away of your old unit, and a labor warranty of 1–3 years. The price shown is the price you pay — no hidden fees, no trip charges, no permit surcharges.

Tank or tankless — which water heater should I get?

A tank system is the most common and lowest upfront cost. A tankless system provides unlimited hot water and uses 20-30% less energy but costs more upfront. WaterHeaterMan's AI sizing tool shows you both options with exact pricing based on your specific home.
