  •  Freeze protection standard
  •  ETL and cETL certified to UL and CSA Standards


CERO Series models have titanium-sheathed elements that will last longer in a caustic environment than standard Incoloy-sheathed elements. CERO Series are electronically-controlled water heaters that calculate the amount of energy needed to meet hot water demand, then activating the minimum number of elements necessary to satisfy that demand. No energy is used when the unit is idle other than the power indicator lamp.


  •  Titanium-sheathed elements last longer in a caustic environment
  •  Electronic controls with minimal working parts
  •  Special air relief system affords increased reliability

  •  Output temperature adjustable in one degree increments from 60 to 185 °F
  •  Accurate to +/- 1 degree F
  •  LED shows output temperature setting and flashes actual temperature if the customer is asking for more heat than is available
  •  Minimal pressure drop
  •  Individually fused elements
  •  Easily serviced on site


  •  NEMA 4 and 4x enclosures
  •  Emergency kill switch (requires NEMA 4 or 4X enclosure)
  •  1″ and 1 1/4″ In/Out piping and valves available, depending on model
  •  Mixing valve available for varying output temperatures in 3/4″ – 1 1/4″ sizes
