How long do hot water systems last?

• Gas Hot Water: 8-12 years
• Electric Hot Water: 10-15 years
• Solar Hot Water: 10 years
• Heat Pumps Hot Water: 15 years

When to replace the hot water system?

Ideally, it should be replaced once it has reached the 10-year mark for storage models. The manufacturer’s label on your hot water system will often include the manufacture date which allows you to estimate the age of your unit.

If you can’t find the manufacturer’s label and are having ongoing problems, it is best to get in touch with a licensed plumber who can check your hot water system and let you know if it'll last for a few more years or whether it needs to be replaced.
