Signs You Need To Replace Your Tankless Water Heater

If you’re not sure whether your tankless gas or electric water heater needs to be replaced, you can start by looking for these signs:

  • Your system is over 15 years old: Tankless water heaters typically last 15 to 20 years. As your unit nears the end of its service life, a replacement is often best.
  • It keeps breaking down. If your tankless water heater is already repaired and it keeps breaking, replacing it might be more cost-effective.
  • It needs costly repairs: If the cost to repair your unit is more than 50% of its value, you’re better off investing in a replacement.

When Tankless Water Heater Repairs Make More Sense

Sometimes, a replacement may not be necessary. You likely need tankless water heater repair if your unit is only a few years old and has any of these issues:

  • Low water pressure
  • Inconsistent temperatures that run hot, then cold, then hot again
  • Mineral buildup
  • Water that’s too hot or not hot enough
Request Service Get started by filling out a service request form or by giving us a call.

Frequently Asked Questions

Your plumber must first remove your old water heater. If you don’t have a gas line and are getting a tankless gas water heater, we’ll run a gas line and install an exhaust vent. If you get a tankless electric water heater, we’ll run electrical wiring to a new circuit breaker.

We’ll then mount the new tankless water heater and perform all the water and electrical or gas line hookups. When the installation is complete, we’ll test your new tankless water heater to ensure optimal operation.

Yes. If your system is too large, you might pay more than you need to on installation and utility costs.

Tankless water heaters work by heating water on demand. When you turn on your hot water tap, cold water will flow through your tankless water heater.

A gas burner or electric heating element will heat the water, which will then immediately flow through your hot water supply pipes and out your faucet.
