Pictured here is a prototype residential product (Model WH 30t) featuring twin 30 gal. tank storage. This design would be selected based on the kind of hot water system in the house and the number of full baths. (See how this model would be used in the Application Guide below).

The model shown is 38 inches wide by 53 inches high, 16 inches deep. The electrodeionization module seen at the top of the prototype is replaced every two years. Prefilters are changed at approximately 6 month intervals depending on incoming water quality.
