Water heaters are integral parts of every home. They supply the hot water you need to bathe, cook, clean, and wash your clothes. Water heaters come in many types and styles, with the tank-style heater being one of the most common and least expensive to install. With a tank-style heater, you store a certain amount of water to be used as you need it. 50-gallon water heaters are designed to hold 50 gallons of hot water, dispensing it as needed. This heater size is ideal for 3-to-5 person households with moderate hot water needs. These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home.

The national average cost to replace a 50-gallon hot water heater is $800 to $2,500, with most people paying around $1,200 for a direct replacement of a 50-gallon gas hot water heater using the same model. This project’s low cost is $620 for a 50-gallon electric hot water heater replacement in an open-and-easily accessed area. The high cost is $3,800 for replacing a high-efficiency 50-gallon gas hot water heater in a new and difficult-to-access location with modifications to fit.

50-gallon hot water heaters are designed for households of 3 to 5 people with moderate hot water needs. These tank-style heaters can be powered by electricity, gas, or propane 1.

Efficiency, fuel type, and replacement location impact your final costs.

Electric hot water heaters tend to be the least expensive to purchase and install, but they can be more costly to run long-term. Gas and propane heaters tend to cost less to run, but they may cost more to install. Gas and propane heaters also come in varying efficiencies, increasing their initial setup costs but decreasing long-term costs. In addition, how easy the area is to install in and whether it needs modifications also impact your final project costs.

Additional Considerations and Costs

  • Top manufacturers. 50-gallon hot water heaters are very common and are produced by many manufacturers. These include Rheem, Bosch, Reliant, and Bradford White.
  • Lifespan. The average lifespan of a tank-style hot water heater is 10 to 15 years, although some last longer.
  • Maintenance. Hot water heater maintenance is generally easy and requires periodically draining the tank to flush out any particulates on the bottom.
  • Mounting. 50-gallon hot water heaters are large enough that they require floor mounting 2. This means you need the floor space for installation.
  • Piping. If you need additional piping to get the hot water from your heater to your home, you may have additional costs between $8 and $10 a linear foot.
  • Permit. Permits are not needed in most areas to install hot water heaters. This can change by municipality, so always check with your plumber or local government for more information.
