Chronomite SR Tankless Water Heaters

Chronomite SR Series Instant-Flow tankless water heaters are compact electric point-of-use water heaters designed for sinks, lavatories, handwashing stations, and under-sink hot water applications. These non-thermostatic tankless units heat water as it flows through the heater, helping reduce wait time when installed close to the fixture.

Shop Chronomite SR by voltage and application

• 120V SR models: small point-of-use applications, single lavatories, hand sinks, breakrooms, and remote sinks where 120V power is available
• 208V SR models: commercial and institutional point-of-use applications where 208V service is used
• 240V SR models: higher-output point-of-use applications where more temperature rise is needed and the electrical service can support the unit
• Low activation models: designed for lower-flow fixtures where activation at reduced GPM is important
• Standard activation models: used where fixture flow rate meets the heater activation requirement

How to choose the right Chronomite SR model

1. Start with the fixture: Chronomite SR units are best matched to sinks, lavatories, and handwashing stations, not whole-home demand.
2. Confirm voltage: choose 120V, 208V, or 240V based on the power available at the installation location.
3. Size by flow rate and temperature rise: compare the fixture GPM with the heater output at your incoming water temperature and desired outlet temperature.
4. Check activation flow: low activation models are helpful when the faucet or flow control may not provide enough GPM to trigger a standard model.
5. Verify electrical requirements: confirm amperage, breaker size, wire size, and single-phase power requirements before ordering.
6. Install close to the fixture: point-of-use water heaters work best when placed near the sink to reduce hot water travel time.

Use filters to narrow by voltage, activation type, kW rating, application, and model number. Not sure which Chronomite SR heater fits?
