Chronomite SR-20 SR Series 4.8 kW Point-of-Use Electric Tankless Review
The Chronomite SR-20 is a 4.8 kW point-of-use electric tankless water heater designed for commercial single-fixture applications. Chronomite is a US-based specialty brand focused on point-of-use commercial water heating since the 1960s.
Specs: 4.8 kW (single 30A double-pole breaker at 240V), 0.7 GPM at a 40°F rise. Brass commercial-grade construction. Patented Patented Thermal Anticipation modulation. 3-year warranty.
The Chronomite SR Series is positioned for light commercial applications: hospital handwash stations, restaurant employee handwash, laboratory sinks, ADA-compliant public restroom fixtures. The brass construction handles thousands of daily cycles in commercial environments where consumer-grade Eemax or EcoSmart point-of-use units would wear faster.
For residential use, the SR-20 is overkill — comparable EcoSmart POU 6 at $200 versus Chronomite SR-20 at $500 delivers similar specs for residential single-fixture use. The Chronomite advantage is commercial-grade reliability under high cycle counts.
Right buyer: light commercial single-fixture application (small healthcare facility, food service handwash, school restroom). Wrong buyer: residential applications (consumer alternatives are cheaper).
