Chronomite SR-20L/208 Instant-Flow SR Tankless Water Heater
Product Overview
The Chronomite SR-20L/208 Instant-Flow SR is a compact electric tankless water heater designed to supply hot water close to a single low-flow sink or lavatory. Instead of storing hot water, the unit heats water as it passes through the heater, making correct flow and electrical matching essential to performance. Its small enclosure and 3/8 in. inlet and outlet connections support point-of-use installation where space near the fixture is limited.
This version is designed for a compatible 208V electrical supply and has listed activation-flow options associated with the application. The water temperature it can deliver depends on the incoming water temperature, actual flow through the faucet, and the heater's electrical input. Before ordering, verify the complete model requirements in the product documentation, including voltage, amperage, wattage, dedicated circuit, breaker and wire sizing, activation flow, plumbing connections, and expected temperature rise. The SR-20L/208 should be selected for one appropriately sized point-of-use fixture and installed according to the manufacturer's instructions; it is not a substitute for a whole-building water heater.
