About Tankless Water Heater Winter Freeze Valve Retrofit

During severe winter freeze events accompanied by power grid blackouts, built-in electric freeze heaters lose power, leaving standing water inside tankless heat exchangers vulnerable to freezing and bursting. Installing a mechanical battery-backed freeze protection solenoid valve in Calumet City, Illinois ensures that if power cuts out during freezing weather, the solenoid automatically opens, safely draining standing water before ice expands.

Tankless Water Heater Winter Freeze Valve Retrofit Questions

How does an auto freeze drain valve work in Calumet City, Illinois?

The spring-loaded solenoid valve requires electricity to stay closed. If power fails during freezing temperatures, the valve opens automatically, draining water out of the unit. Call (888) 905-6092 to install one in Calumet City, Illinois.

Why aren't standard built-in freeze heaters enough during a storm?

Built-in freeze heaters rely on 120V household electricity. If the power grid drops during a freeze, built-in heaters stop working. Call (888) 905-6092 for fail-safe protection.

Can an auto freeze valve be retrofitted on any tankless model?

Yes, auto-drain solenoid valves connect to standard 3/4-inch isolation flush ports on all major brands. Call (888) 905-6092 for an estimate.

Our Navien NPE unit was leaking water from the bottom and throwing error E003. The technician diagnosed a leaking internal recirculation pump and swapped it out on the spot with an original factory part. Honest upfront pricing and super clean work.

We hadn't flushed our tankless water heater in four years and hot water pressure dropped to a trickle. Their team performed a chemical descaling flush and cleaned out the inlet filter screen. Water pressure is completely restored to day-one performance.
