5 Unusual Mistakes That Reduce Tankless Water Heater's Life

A tankless water heater is like a reliable friend—always ready to deliver hot water when needed. But just like any friend, if you don’t treat it right, it won’t stick around for long. Many homeowners unknowingly make mistakes that shorten their unit’s lifespan.

If you want to avoid costly replacements, read on.

1. Ignoring Regular Maintenance

You wouldn’t drive your car for years without an oil change, right? The same rule applies to tankless water heaters in Markham. Over time, mineral buildup clogs the system, reducing efficiency. If left unchecked, it forces the heater to work harder, leading to breakdowns.

Scheduling annual maintenance with HVAC contractors in Markham can prevent costly repairs. A simple flush removes scale buildup, keeping your system running smoothly for years.

2. Skipping the Water Softener

Hard water is a silent killer for your tankless unit. The minerals in hard water settle inside the heater, restricting water flow and overheating the unit. This leads to early failure, forcing you to replace the system sooner than expected.

Installing a water softener is a smart investment. It removes excess minerals, protecting your heater and ensuring consistent performance. Many homeowners overlook this step, only to regret it later when their system breaks down prematurely.

3. Setting the Temperature Too High

Some believe that cranking up the temperature gives them better hot water. In reality, it only puts extra stress on the heater. Our expert gas furnace service providers in Markham recommend keeping the temperature at 120°F. Anything higher increases wear and tear.

High temperatures also lead to scalding and increase energy bills. Instead of pushing your heater to the limit, keep it at a safe and efficient level.

4. Blocking the Air Supply

A tankless water heater needs proper ventilation to function safely. Many homeowners install storage boxes or place objects near the unit, unknowingly blocking airflow. This leads to overheating, system failure, and even carbon monoxide buildup in extreme cases.

Ensure your heater has enough space for proper airflow. If you’re unsure, call Air Leaders for expert guidance on safe installation. A simple adjustment can prevent major issues down the road.

5. Choosing the Wrong Size Heater

One of the biggest mistakes homeowners make is buying the wrong size heater. If your unit is too small, it struggles to meet hot water demands, running constantly and wearing out faster. On the other hand, an oversized heater wastes energy.

Before purchasing, consult professionals who specialize in tankless water heaters in Markham. They assess your household’s water needs and recommend the right size, ensuring maximum efficiency and longevity.

Final Thoughts

A tankless water heater is an investment, but simple mistakes can cut its life short. Ignoring maintenance, skipping water softeners, setting the temperature too high, blocking airflow, and choosing the wrong size all take a toll on your unit.
