Titan SCR4 N-180 Tankless Specifications

Physical Specifications

• This water heater measures 11.5 inches tall by 10.5 inches wide by 3 inches deep and it weighs 14 pounds. Its casing is made of brass, and its standard threaded pipe fitting is 1/2 inch in diameter. Its housing is metallic in color, except for a red nameplate as well as a red control panel, which includes a black thermostat dial, a red "On" indicator and a green "Standby" indicator.

Power and Pressure Requirements

• The Titan SCR4 N-180 requires 18 kilowatts of 240 volt AC power, although 208 and 277 volt versions are available. Since its maximum amperage at 240 volts is 77 amps, two 40 amp circuit breakers and 8-gauge wire must be used to install and connect the heater. The minimum water pressure needed for this unit to operate is 5 PSI, and the maximum pressure at which it can operate is 150 PSI.

Heating Performance

• At one GPM (gallon per minute), the SCR4 N-180 produces a 122 degree Fahrenheit rise in water temperature. At 1.5 GPM the temperature rise is 81 degrees, at 2 GPM it is 61 degrees, at 2.5 GPM it is 49 degrees, at 3 GPM it is 41 degrees, at 3.5 GPM it is 35 degrees and at 4.0 GPM it is 31 degrees.

Other Specifications and Features

• The heating elements of the Titan SCR4 N-180 are made of Incoloy, a nickel-iron-chromium (nichrome) alloy. This heater is rated at up to 99.5 percent energy efficiency, and it can be activated at 0.4 gallons per minute, whereas it switches off at 0.3 gallons per minute. It is controlled by a dual microtemp thermistor manual resettable thermostat.

Conformity to Standards

• The Titan SCR4 N-180 conforms to the following safety and performance standards: UL (Underwriter's Laboratories) 499, ANSI-Z (American National Standards Institute) 10.03 and Dade Approval (Miami-Dade County, Florida) 96-0311.03. It was tested by Applied Research (Number 29,580)
