Keeping Your Tankless Water Heater Happy During the Holiday Season


Tank vs. tankless water heaters: Despite their energy efficiency and varying sizes, both types share common issues. A tankless water heater heats water directly from your home’s water line, utilizing a gas or electric heat exchanger. However, hard water minerals can accumulate, causing wear and potential plumbing clogs in both systems. This mineral buildup damages the tank in traditional heaters and the heat exchanger in tankless models.

Routine maintenance is crucial for the longevity and efficiency of your tankless water heater. While professional maintenance from MillTown is essential, you can perform a few simple tasks to ensure your system remains in top condition.

Tips to Maintain Your Tankless Water Heater

  • Maintain Clear Space: Your tankless water heater combusts fuel for heat, so it’s vital to keep flammable materials such as paper, clothing, paints, and chemicals at a safe distance. Ideally, store all combustible items in a different room.
  • Inspect the Exhaust Vent: Proper ventilation is essential for the efficient operation of a tankless water heater. Regularly clean the exhaust vent to remove dust and debris, preventing airflow restriction and potential carbon monoxide hazards.
  • Monitor for Leaks: Leaks in your tankless water heater’s plumbing can lead to significant issues if left unaddressed. Check nearby pipes for drips or pools of water and contact a plumber immediately if you discover any leaks.
  • Keep It Clean: Dust and dirt can accumulate on your tankless water heater. Regularly clean the exterior with a lint-free cloth and mild detergent to keep it free of dust and debris.
  • Clear the Drain Valve and Water Screen: Dirt and debris can obstruct the drain valve and water screen, affecting water flow. Periodically inspect and clean these components as needed.
  • Descale Regularly: Even with a water softener, mineral deposits can build up in your tankless water heater over time. Descale or flush your unit at least once a year to prevent excessive mineral accumulation.

When to Contact MillTown for Help

No matter how well you maintain your tankless water heater, issues can still arise. It’s critical to address these problems promptly to avoid higher water bills or premature replacements. If you’re experiencing any of the following issues in your Chelmsford, MA home, contact MillTown for professional assistance:

  • Warm Water: If your water heater is no longer producing hot water, it could be due to various issues, such as a required temperature adjustment or excessive water pressure. A professional plumber can diagnose and resolve the problem efficiently.
  • Unit Shuts Off Unexpectedly: A clogged filter can cause your tankless water heater to shut off. Cleaning or replacing the filter typically resolves the issue.
  • Inconsistent Water Temperatures: If your water temperature fluctuates drastically, a loose connection within the unit may be to blame. Professional repair is necessary to fix this serious issue.
  • Non-Functional Water Appliances: Your dishwasher or washing machine might not operate correctly if your water heater fails to provide adequate heat and pressure. Adjust the hot and cold valves to see if it resolves the problem; if not, call a plumber for assistance.
