Why isn’t the smart solution for water heaters recommended for water heaters that are over 10 years old?
When replacing a water heater, the temperature probe on the controller must also be replaced. Replacement probes are available at no cost. To order one, contact our customer services. The probe will be mailed to you, and you can either install it yourself or have it installed by a professional.
Note: The risk of Legionella increases as the water heater ages. Read the FAQ to learn more about Legionnaires’ disease (legionellosis).
