Product Overview
The Eemax SPEX75 FlowCo is a 7.5kW, 240V tankless electric water heater for compatible point-of-use fixtures. It activates at approximately 0.3 GPM and provides a listed 51°F temperature rise at 1.0 GPM, making it suitable for carefully sized sink and similar low-flow applications.
The heater should be matched to the actual fixture flow, incoming water temperature, and desired outlet temperature before purchase. Higher flow or colder inlet water will reduce the available temperature rise, so maximum values should not be used as a sizing shortcut. The SPEX75 uses top or bottom 1/2 in. NPT water connections and a dedicated 40A circuit according to the stored specifications. Confirm the breaker, wire size, plumbing layout, mounting location, pressure range, and indoor freeze protection before installation. Run water through the heater to purge air before energizing the circuit.
