Save Money and Stay Cozy: Tips for Prepping Your Tankless Water Heater for Winter

As winter approaches, it’s crucial to prepare your tankless water heater to prevent freezing and costly damage. Follow these steps to ensure your water heater stays operational throughout the cold season:

1. Insulate the Water Heater

Insulating the water heater reduces heat loss and prevents freezing. Wrap the unit with insulation blankets specifically designed for tankless water heaters. Secure the blankets tightly to prevent gaps.

2. Install a Heat Tape

A heat tape is an electric heating cable that can be wrapped around the water heater‘s pipes and fittings. It provides an additional heat source to keep the water flowing even in sub-freezing temperatures.

3. Check the Temperature Setting

Adjust the water heater‘s temperature setting to a lower level during winter. This will reduce the risk of overheating and extend the heater’s lifespan.

4. Drain the Water Lines

If you’re leaving your home unoccupied for an extended period during winter, it’s essential to drain the water lines. Turn off the water supply and open all faucets and valves to release the remaining water.

5. Add Antifreeze

In regions with extremely cold temperatures, consider adding non-toxic antifreeze to the water heater‘s system. This will prevent freezing and damage to the internal components.

6. Flush the Water Heater

After draining the water lines, flush the water heater by turning on all faucets and valves until clear water flows. This removes any remaining antifreeze or sediment.

7. Protect from Wind and Snow

Place a cover or enclosure around the water heater to protect it from wind and snow. This will help maintain the unit’s temperature and prevent ice buildup.

8. Monitor Water Flow

During winter, monitor the water flow from your faucets and showerheads. If you notice any reduced flow, it could indicate a frozen pipe or blockage. Contact a plumber immediately to address the issue.

9. Consider a Recirculating Pump

A recirculating pump can help prevent freezing by continuously circulating warm water through the pipes. This is particularly beneficial in homes with long plumbing runs.

10. Check the Drain Valve

Ensure the drain valve at the bottom of the water heater is not frozen or obstructed. This valve allows for easy draining of the unit if necessary.

11. Power Off

If you’re leaving your home unoccupied for an extended period, consider turning off the power to the water heater to prevent any potential electrical issues.

12. Contact a Professional

If you’re not comfortable performing any of these steps or encounter any difficulties, don’t hesitate to contact a licensed plumber for assistance.
