TITAN SCR4 N-180 ELECTRONIC TANKLESS WATER HEATER – 18 KW, 77 AMP, 240V – MODEL N-180

The Titan SCR4 N-180 Electronic Tankless Water Heater, manufactured by Niagara Industries, is a high-capacity electric on-demand water heater designed for homes with greater hot-water demand. Its digital microprocessor-controlled system delivers up to 18 kW at 240V, while the tankless configuration eliminates the need to continuously maintain a conventional storage tank of hot water.

Overview

The SCR4 N-180 is designed for higher-demand residential applications, including homes in colder regions and installations requiring faster filling of large tubs, garden tubs, or Jacuzzis. Titan rates the system for water flow up to 5 GPM, with actual temperature rise depending on incoming water temperature and flow rate.

The TITAN SCR4 Electronic Tankless Water Heater is a high-performance electronic tankless water heater designed to deliver continuous, on-demand hot water without the need for a storage tank. With 18 kW of power and operating at 240 volts and 75 amps, this unit provides efficient and reliable hot water for residential applications while reducing energy consumption compared to traditional tank heaters.Its compact and space-saving design allows for flexible installation in small areas, making it ideal for apartments, condos, and homes where space is limited. The advanced electronic control system ensures consistent water temperature and optimized performance.
