Signs You Need a Replacement Water Heater

It’s important to know when to replace your water heater to prevent any disruptions to your hot water supply. These are some of the telltale signs it’s time to consider upgrading your water heater:

  • System age: Standard tank units typically last eight to 12 years, while tankless water heaters require replacement every 20 years or so. If your unit is nearing this age, it may be time for an upgrade.
  • Repair frequency: If you’re scheduling water heater repairs more frequently, it may be a sign that your system is nearing the end of its usable lifespan.
  • Reduced efficiency: A notable decline in efficiency is typically accompanied by an unexplained rise in your water bills. If you notice this, it may be time to consider water heater replacement.
  • Repair cost: When the cost to repair your water heater is 50% or more than the price to replace it, upgrading to a new unit may be the more cost-effective solution.

Water Heater Installation FAQs


Water heater installation typically takes about two to four hours, depending on the type of heater and the complexity of the installation, such as modifications to plumbing or electrical connections.

The size of the water heater you need depends on your household size and hot water usage. Generally, a 30–40 gallon tank is suitable for one to two people, 40–50 gallons for three to four people, and 50–80 gallons for larger households.

Depending on your needs, you can choose between a tankless or traditional water heater. Tankless models offer on-demand hot water and energy savings, while traditional tanks are generally less expensive upfront and provide a ready hot water supply.
