Compact point-of-use heater

The Chronomite SR-20L/120 HTR-I is a 2400 W electric tankless water heater designed for residential and commercial point-of-use applications. It delivers unlimited hot water on demand without the standby losses of a storage tank. The compact wall-mount design allows installation in tight spaces where a traditional heater would not fit.

Efficiency and electrical load

The unit operates at a 99 % energy efficiency rating, converting nearly all input power into heated water. It runs on a 120 V supply, drawing 20 A during operation. Because it only activates when water flows, there is no continuous power draw or noise when hot water is not being used.

Simple connection and mounting

A 3/8" compression water connection enables quick plumbing without soldering or specialised tools. The lightweight housing mounts directly to the wall, reducing installation time and hardware. No additional accessories or software are included, so the heater is ready for immediate integration into existing hot-water lines.

Questions about this item

How is the 3/8" compression water connection installed, and what step do people get wrong?

Slip the compression nut and ferrule onto the tubing, insert the tube fully into the heater fitting, then tighten the nut by hand plus one-half turn with a wrench; the common error is tightening before the tube bottoms out, which leaves a leak path.

What maintenance or replacement will the heating element need later?

The element is sealed inside the chamber and is not user-serviceable; if scale buildup reduces flow or temperature rise, the entire unit must be replaced.

What limit appears first during sustained 2400 W operation on a 120 V circuit?

The 20 A branch-circuit breaker will trip if the heater runs continuously with other loads on the same circuit, because the unit draws the full 20 A at rated power.
