Model CA-32

Four-Chamber Tankless Electric Water Heater

Description: The CA-32 is used in demanding applications where incoming water temperatures or total flow requirements dictate more power than the CA-28. Ideal for the commercial applications such as: offices, specialty restaurants, convenience stores, salons and pet-grooming shops. This on-demand tankless water heater is a powerful replacement for traditional tank-type heaters or for use as a booster to a traditional tank water heater or active renewable energy systems such as solar and geothermal water heating systems. The temperature activated control works effectively in re-circulating systems or in combination with tank-type heaters or in-line boosters to supply specialized requirements.
