That electrical input must be evaluated together with the site's incoming water temperature and the fixture's actual flow rate because all three affect the attainable outlet temperature. Before ordering, calculate or confirm the required temperature rise and verify the voltage, dedicated circuit, breaker and wire sizing, flow and activation conditions, plumbing connections, and available mounting space. The SR-20L\/240 is designed to serve an appropriately sized point-of-use fixture; it should not be selected as a whole-home heater or for a flow demand outside the documented performance range.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePoint-of-use electric tankless water heater\u003c\/li\u003e\n\u003cli\u003eLow-flow SR Series model\u003c\/li\u003e\n\u003cli\u003e240V, 20A, 4800W electrical rating\u003c\/li\u003e\n\u003cli\u003e0.5 GPM listed flow rate\u003c\/li\u003e\n\u003cli\u003e3\/8 in. cold water inlet and outlet connections\u003c\/li\u003e\n\u003cli\u003eCompact steel housing for under-sink installation\u003c\/li\u003e\n\u003cli\u003eRear electrical knockout and mounted chrome compression fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCommon Uses:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLavatory hot water\u003c\/li\u003e\n\u003cli\u003eBar sink point-of-use hot water\u003c\/li\u003e\n\u003cli\u003eLow-flow handwashing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 240V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 20A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage:\u003c\/strong\u003e 4800W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate:\u003c\/strong\u003e 0.5 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e 3\/8 in. inlet and outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e SR-20L\/240\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 9.6 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 2.8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 6.2 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.4 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eInstallation \u0026amp; Compatibility Note:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eElectric tankless water heaters must be matched to the correct voltage, amperage, breaker, wiring, flow rate, and application.
