Niagara Industries is the manufacturer of the popular Titan water heaters, electrical and tankless products made to heat potable water in residential and commercial applications.

Every Titan tankless heater is built as the wall-hanging unit that occupies less than one square foot of space, making it ideal for homes that lack space.

Titan models heat water on demand. The tankless design eliminates the energy waste, known as the standby heat loss, plus it provides an endless supply of hot water with energy savings of 40% and more.

Titan incorporates several great features, such as the digital control platform that provides real-time readings and reliable and long-lasting shielded Incoloy heating elements that work great even in regions with hard water.

Review of popular Titan models

There are four categories available:

Titan SCR2

Titan water heaters from the SCR2 series are small electric models using advanced technology for faster water heating and more accurate outgoing temperatures.

These popular models use a microprocessor that checks the incoming and outgoing water temperature over 20 times per second, resulting in less temperature fluctuation, stable temperature, and maximum energy efficiency of the units.

There are seven models available in the SCR2 series, where the power range goes from 3.2 to 11.8 kW, which makes them great for various applications. Lower-power models N-10, N-42, N-64, and N-75 are designed for point-of-use service only, while the smallest models produce just the warm water. Other models are used for whole-house water heating, and the biggest model, N-120, is recommended for homes with one to three bathrooms.

Model N-10 N-42 N-64 N-75 N-85 N-100 N-120

Titan SCR3

One of the main features found on the Titan SCR3 is the digital LCD that displays the real-time usage, power in kW, voltage, amperage, and diagnostics. SCR-3 model utilizes the "QUAD-4" technology that allows greater temperature stability when the water flow varies.

This model is recommended for both modern and older homes (retrofit), from small to large size (depends on the climate), as long as the voltage is from 208V to 240V.

Only one model is available, N-160, and it comes with the maximum power of 12 kW when operating on 208V or 16 kW when operating on 220V.

Model N-160
kW 12 (16)
Temp. rise @ 1 g/min 109
Voltage (V) 208 (220) - 240
Amps (A) 55 (65)
Wire 6 (4/6) AWG

Titan SCR4

Titan water heaters from the SCR4 series utilize three heating elements designed for homes with high hot water demand and homes located in colder regions. The Titan SCR4 is comprised of two models; 18 and 21 kW.

Model N-180 N-200
kW 18 21
Temp. rise @ 1 g/min 122 143
Voltage (V) 240 240
Amps (A) 75 88
Wire 8 AWG 8 AWG

Titan Laser models are manufactured for Caribbean, Central, and South American countries, and because of the low power consumption, they can be used in areas where the power is limited.

Model L-64 L-75 L-85
kW 6.4 7.5 8.5
Voltage (V) 220 220 220
Amps (A) 29 34 38

Titan N-140

The Titan N-140 model is the latest release from this manufacturer. Like other models, it is also designed as the tankless unit for fast water heating but with the newest and patented digital control and LCD, which provides beneficial information for the users; real-time usage, power, Watts, Amps, Volts, and efficiency. It is recommended for medium and large homes in warmer regions or small to medium-sized houses in colder areas.

Titan tankless water heaters are easy to install as long as the requirements in Amperage, Voltage, breaker size, and other codes are met. Due to their small and compact size, they can be mounted almost anywhere inside the house. Even with the high resistance to sediment build-up, installing a sediment filter in the area with extremely hard water is recommended.
