When do you need a replacement or new installation?
Most homeowners come to us when something just isn’t working right anymore. You might need a replacement or upgrade if:
» You’re running out of hot water regularly
» Your water temperature is fluctuating
» Your power bills are increasing
» Your cylinder is leaking or showing signs of wear
» Your system is over 10–15 years old
Hot water systems naturally become less efficient over time, and replacing them can improve both performance and energy efficiency.
