Is the Average Water Heater Replacement Cost Expensive?

When you have problems with your hot water heater, you need to determine whether it is better to repair it or replace it. One important consideration is the average replacement costs of hot water heaters, which depend on four factors:

  1. Age of the water heater. On average, tank-type heaters last between 10 to 15 years. Tankless heaters tend to last up to 20 years. If your current heater is nearing the end of its useful lifespan, it might be worthwhile to have it replaced rather than repaired.
  2. Cost of repairs vs. replacement. You need to compare the costs of repairs to the cost of having a new water heater installed. For instance, your estimate for repairs is $500, and the cost to get a new tank-type heater is $700. Since there is not much difference in cost for this scenario, it would be better to invest in a new water heater.
  3. Type of water heater. The type of water heater being replaced does influence the cost. Electric heaters tend to cost less compared to natural gas and propane-type heaters. There are also variances in costs between tank-type and tankless heaters you need to evaluate.
  4. Size, capacity and/or gallons per minute of the heater. For tank-type heaters, there will be differences in cost based on the size and capacity of the heater, as well as the number of gallons per minute it will deliver. For tankless heaters, there are variances in cost based on the gallons per minute of hot water the heater can generate.

Whether the average replacement cost is expensive will vary based on your budget and household needs. Costs run from around $800 with installation to several thousands of dollars for a high-end tankless system. Please keep in mind, to determine your actual replacement costs, you would need to request a free quote.
