Product Overview
The Eemax SPEX55 FlowCo is a compact 5.5kW, 240V tankless electric water heater for compatible point-of-use fixtures. It activates at approximately 0.3 GPM and uses 1/2 in. NPT top or bottom water connections, giving installers flexibility when routing plumbing in a properly sized low-flow application.
This model is best selected by comparing the fixture's actual flow rate with the required temperature rise from the site's incoming water temperature to the desired outlet temperature. A small tankless heater can be a useful solution for a sink or remote fixture, but it is not sized by wattage alone and should not be assumed to serve higher-flow fixtures. Confirm the available 240V circuit, breaker, wire size, plumbing orientation, indoor mounting location, and freeze protection before ordering. The water lines should be flushed and air purged from the unit before electrical power is applied.
