Titan N120 Tankless Water Heater Review

In Brief: Review of Titan N120 Tankless Water Heater

The Titan N120 is a moderately priced tankless water heater. It has a much smaller body than other heaters and can handle hard water better. The energy efficiency helps buyers earn back the initial investment. This works best for two-bedroom homes with up to three bathrooms. Installation isn’t too difficult and can be done by the owners themselves.

Titan water heaters are manufactured by Niagara Industries Inc. The company has been in the industry for 34 years and is headquartered in Florida, Miami. They were the first to make a fully electric tankless water heater.

The Titan N120 is a compact bodied tankless water heater. It is known for its energy efficiency and for being affordable. It is much easier to install than most tankless water heaters.

Key Specifications of Titan N120 

Titan Electric Tankless Water Heater

The Titan N120 is a part of the Titan SCR2 series of tankless water heaters. These systems are designed to supply instant hot water. Because of this, they eliminate the need for bulky storage tanks.

These heaters have dedicated analog microprocessors that sample the output and input water temperature 21 times per second. This ensures that only the minimum amount of energy required is consumed.

The power control system takes care of this and also stabilizes the temperature. The SCR2 heaters save both energy and space. Their energy efficiency is 99.5% and the N120 model is no larger than a phone book.

It features a manually resettable thermostat and a more accurate temperature sampling system. A new air/water differential analyzing system prevents dry starts.

The shielding Incoloy heating elements and copper brass casing prevents the damage caused by mineralization in standard water heaters.

Can I only change the breaker and use the existing wiring in my home?

If you are replacing a tank heater with this tankless one, you will need to change the wiring as well.

Does this heater need to be cleaned?

If the supply water is hard, then there can be scale build-up on the intake filter. The company provides for servicing if you face such problems.

How much clear space does this heater need around it?

As the system dissipates heat, it needs about 4 inches of space around all sides.

Our Recommendation

The Titan N120 is an ideal tankless water heater for homes with up to three bathrooms. It is also suitable for homes in regions with a temperature of 65 degrees Fahrenheit or more.

It works better with hard water than most water heaters and has a good warranty package. The heating components also have a long life.

This is a good investment for people looking for instant and endless hot water supply at a reasonable price.
