The RediHeat instantaneous water heater is designed with a unique feed-forward temperature control system to instantly produce hot water within ±4°F of the set temperature under widely varying demands. The unit features a spiral-tubed helical heat exchanger for efficient heat transfer in a compact space. The rugged casing and bourdon tube configuration allows the entire assembly to expand and contract without localized stressing. The simple mechanical design allows the water temperature to be controlled by a mechanical blending valve that operates based on demand. A manual adjustment compensates for seasonal changes in cold water supply temperature. The unit requires no extraneous power sources, controls or temperature sensors, making installation easy. When maintenance on the helical heat exchanger is required, the coiled tub bundle can either be cleaned in pace or removed for cleaning.
