Important Winter Storm Reminder for Tankless Water Heaters
Freezing temperatures can cause serious damage to tankless water heaters—even during short cold snaps. The image below outlines manufacturer-recommended preventive maintenance steps to help protect your unit during winter storms.
Key reminders:
✔️ Drain the unit if it will be exposed to freezing conditions or shut down for an extended period
✔️ Insulate hot and cold water pipes (but never drain or pressure relief valves)
✔️ Electric freeze protection only works when the heater is powered and filled with water
✔️ Do NOT use antifreeze inside the system
✔️ Failure to take proper precautions can result in damage not covered under warranty
A little preparation can prevent frozen pipes, leaks, and costly repairs. Stay safe, stay warm, and protect your equipment this winter!
