Electric tankless heater for indoor use

The Chronomite R-48L/208 is an electric tankless water heater designed for indoor commercial and residential applications. It operates on a 208V AC single-phase supply and delivers hot water on demand without a storage tank. The unit activates at a minimum flow of 0.34 gpm and can supply up to 5 gpm.

Compact wall-mount design with NPT inlet

Installation involves mounting the compact enclosure, which measures 4.25 in deep by 9.88 in high by 10.63 in wide, and connecting the 3/4 in male NPT cold water inlet. The unit draws 48 A at 10,000 W, so the electrical service must support this load. Undersized wiring or an inadequate breaker are common issues that prevent correct operation.

Adjustable thermostat sets delivery temperature

The built-in adjustable thermostat controls the output temperature between a minimum of 70 Degrees F and a maximum of 125 Degrees F. This range determines whether the heater meets the specific temperature requirements of the intended application. Buyers needing temperatures outside this window should consider a different solution.

The heater has a 3/4 in male NPT cold inlet; supply piping, fittings, a 208 V single-phase circuit rated for 48 A, and a 10,000 W breaker are not included.

Which flow rate and temperature range suit my application best?

The unit delivers up to 5 gpm with an adjustable output from 70 to 125 degrees F; choose a lower set point for hand-washing or a higher one for commercial sinks.
