Chronomite Instant-Flow® SR
Electric Tankless Water Heaters

Chronomite Instant-Flow® SR
Electric Tankless Water HeatersThese Chronomite Instant-Flow SR tankless electric water heaters are manufactured to provide you unlimited hot water without a factory preset temperature. Designed for 99% energy efficiency these tankless electric water heaters are useful for many commercial, industrial and residential applications. Please keep in mind that because there is not a factory preset temperature these units must not exceed a maximum temperature of 140°F and 150psi per UL and IAPMO standards. Since there is no storage tank a temperature and pressure relief valve is not required unless specified by local code authorities. Small compact size (6-1/4" x 9-5/8" x 2-3/4") with 1/4" female NPT inlet/outlet makes for convenient installation in tight quarters helping to reduce installation costs.
Standard models operate with a minimum flow rate of 1gpm and a minimum pressure of 25psi and work great for commercial, industrial, residential, lavatory, shower, kitchen/bar sink, service and scrub sink, applications.
Low flow models operate with a minimum flow rate of only 0.4gpm and a minimum pressure of 25psi and work great for commercial, industrial, residential, lavatory, kitchen sink and bar sink applications.
These Chronomite Instant-Flow® SR Series Electric Tankless Water Heaters must be supplied with cold water only to the inlet.
