FAQs
Frequently Asked Questions
Why Replace Your Hot Water Heater?
Hot water technology is always evolving, with more robust, power-saving and environmentally-friendly solutions available.
Your hot water heater may have been in your home or office for over a decade, so whether you want to upgrade your electric hot water heater, make the switch to solar or gas, or need to replace an old, faulty heat pump system, the Ausco team have the skills to get the job done right.
How Long Do Hot Water Heaters Last?
The lifespan of your hot water system depends the brand, how it’s been maintained, and the type of system (electric, gas, solar or heat pump). Gas hot water heaters, for example, can last up to 20 years, while electric hot water systems generally don’t need to be replaced for over 12 years. The warranty on your hot water heater can be an indication of the expected lifespan.
If you find yourself frequently needing to call out a plumber to repair your hot water heater, it may be time to get it professionally replaced with a new model.
