Hot water is something most homeowners take for granted, until it stops working. If your system is struggling, it may be time to consider a water heater replacement.
If you’re unsure whether you need a repair or a full replacement, here’s what to look for.
How Long Do Water Heaters Last?
- Tank water heaters: 8–12 years
- Tankless systems: 15–20+ years
If your system is approaching this range, it’s worth having it checked before it fails unexpectedly.
Common Signs You May Need a Replacement
- Rusty or discolored water
- Rumbling or banging noises
- Leaks around the tank
- Water not heating properly
- Running out of hot water quickly
Some of these issues can be repaired. Others indicate the unit is nearing the end of its life.
How Long Does Replacement Take?
Most water heater replacements can be completed in 3–4 hours by a licensed plumber. This includes removing the old unit, installing the new system, and testing everything for safety and performance.
Should You Replace It Yourself?
Water heater replacement involves plumbing, electrical, and in some cases gas connections. Mistakes can lead to leaks, damage, or safety risks. For most homeowners, it’s best handled by a licensed professional.
