How often should I descale my tankless water heater in Calgary?

Answer: Because the Calgary and Airdrie area has significantly hard water, we recommend professional descaling once every 12 months. Regular flushing removes calcium and scale buildup, which protects your heat exchanger, maintains energy efficiency, and ensures your manufacturer’s warranty remains valid.

What are the most common signs my tankless water heater needs repair?

Answer: The most common indicators are fluctuating water temperatures (often called a “cold water sandwich”), unusual rumbling or clicking noises, or specific error codes on your unit’s display. If you notice a drop in hot water pressure or your unit is “short-cycling,” it’s time to have a licensed technician inspect the sensors and venting.

Is it better to repair or replace an older tankless water heater??

]Answer: Most high-quality tankless units (like Navien or Rinnai) are designed to last 15–20 years. If your unit is under 10 years old, a repair or component replacement is usually the most cost-effective path. However, if the heat exchanger is leaking or the repair costs exceed 50% of a new high-efficiency installation, we provide transparent quotes to help you decide on the best long-term value.g.
