The Noritz EZ111DV (GQ-C3260WX-FF US) and EZ98DV (GQ-C2860WX-FF US) are condensing tankless gas water heaters designed for residential or manufactured home applications. These devices provide on-demand hot water, eliminating the need for a storage tank and offering energy efficiency by heating water only when needed.
The primary function of these Noritz tankless water heaters is to supply continuous hot water. Unlike traditional tank-style water heaters, they do not store hot water. Instead, when a hot water fixture is opened, cold water flows into the unit, where a gas burner rapidly heats it to the desired temperature. The condensing design incorporates a secondary heat exchanger that recovers heat from the exhaust gases, improving efficiency and reducing energy consumption. This process also results in the discharge of condensate, a normal byproduct of the high-efficiency operation.
The water heater is equipped with an ignition device that automatically lights the burner, eliminating the need for a pilot light. This ensures safe and efficient operation. The unit's operation is managed via a remote controller, which allows users to set and monitor the hot water temperature. The controller also features indicators for power, burner activity, and priority settings, as well as an alarm for flow meter settings, useful for filling tubs to a preset volume.
Safety is a critical aspect of the device's design. It includes features to prevent scalding, such as temperature limiting options and warnings for high-temperature settings. The unit also incorporates freeze prevention heaters that automatically protect the internal components from freezing, even in cold environments, as long as the power supply is maintained. However, external plumbing requires additional protection in extremely cold conditions. The device is designed to conform to various safety standards, including the National Fuel Gas Code and Manufactured Home Construction and Safety Standards.
Operating the Noritz tankless water heater is straightforward, primarily managed through the remote controller (RC-7651M-A).
Regular maintenance is crucial for the longevity and efficient operation of the Noritz tankless water heater.
