The best Titan water heater is reliable since it generates hot water on demand, in endless supply, and with the steady temperature. The best model is high efficient - 60% higher efficiency than the tank-type. It is also long-lasting - expected life cycle is over 20 years. Than, it is economical because it is cheaper to buy than gas or tank-type. And, it is small and simple - easy to carry, handle, and install.

The best models utilize innovative and state-of-the-art technology resulting from the company's collaboration with experts such as NASA. These include the P.I.D. controller that eliminates old ON/OFF technology, copper and brass elements that help in hard water and sediment build up resistance, a technology that prevents dry starts, and more.

With the small and compact size of 12" x 9" x 2.75" and weight of up to 12 pounds, Titan models are very easy to handle, and with the standard connections, single-phase and voltage of up to 220 V, they are easy to install - almost in any part of the house.

FOR EXAMPLE, Titan SCR2, Laser, and Laser SH models are the new generation of electronic tankless water heaters that utilize this advanced technology, including the High-Speed Electronic Integrated Circuitry.

Titan water heaters can be used for a variety of applications residential and commercial, from small offices, also hotels, malls, and large homes providing on-demand, endless hot water without annoying temperature fluctuation, and with the energy, money, and space savings for the users.

Models review

´╗┐There are several categories of Titan water heaters you can choose from. They all use the tankless system to heat the water, smaller recommended for the warmer region and larger for colder.

  • Titan SCR2
  • Titan SCR3
  • Titan SCR4
  • Titan Laser


One of this company's latest electric and tankless water heaters is the Titan-SCR2 model, comprised of several models (sizes), where the N-120 is the most powerful and with the highest water flow rate. It features the microprocessor to monitor the usage and automatically adjusts its power, which results in better comfort - due to the reduced fluctuation of hot water temperature. At the same time, it optimizes itself so it can use less power, which means more savings for you.

TEMPLOGIC technology is what makes Titan-SCR2 one of the most advanced tankless water heaters available.

Titan SCR3

Titan water heater SCR3 is an electric tankless unit with excellent performance, efficiency, and reliability. Only one model, N-160, is available in this series.

The SCR3 uses the latest technology called QUAD-4 and features an improved electronic proportional control system with power modulation for energy-saving heating.

The SCR3 is equipped with a digital display located at the front of the unit, and it provides great info to the user; real-time usage, temperature, power, and efficiency.

It provides better temperature control during any water flow, even in modern bathroom fixtures. The best results with high efficiency and accuracy are obtained when the unit operates on 208 V and with the modern flow. It also performs well when the standard voltage of 220 V is used.

With only 9 pounds and small size of 7" x 10" x 3", it can be installed virtually anywhere, but mainly at the point of service. There are two power settings available for the N-160 model; 12 kW when it operates on 208 V and 55 Amps, and 16 kW when it works on 220 V and 66 Amps. In both cases, Titan tankless water heater SCR3 provides a maximum of 4 GPM supplying enough hot water from medium to large homes and apartments.

Titan SCR4

If you need a water heater with a larger capacity or higher temperature rise (if you live in colder northern U.S. states), Titan SCR4 is a solution for you, as it supplies up to 5 G.P.M.

SCR4 is a little heavier and larger than SCR3; it weighs 12-13 pounds and comes in a small and compact size of 11,5" x 10,5" x 3".

Titan water heaters from the SCR4 group, are available as N-180 and N-210 models, and by using 240 V with 75 and 88 Amps, they provide 18 and 21 kW of heating power and up to 5 GPM of hot water - perfect for larger houses in colder areas.

Titan SCR4 is excellent for heating water in regions with hard water or water with a higher percentage of mineral deposits. Modulation brings savings and increased comfort, so when the voltage reduces, the heating power also drops. SCR4 models are also available in stainless steel casing which provides additional protection, especially in the harsh environment.

Titan Instant Electronic Water Heater - Laser

The Titan water heater Laser model is the energy-efficient electric unit that utilizes a shielded Incoloy heating element, a reliable and durable material, and is very resistant to hard water and sediment buildup.

It uses the Linear Electronic Temperature Control, the component that controls the hot water temperature and how to adjust the output temperature. With three models available, it can cover from 0-8.5 kW of heating power and is only available for the export market.

Titan water heaters are perfect for new installation and new homes and can substitute large tank-type units in existing homes, even commercial applications. They are designed for a wide range of residential and commercial applications that can provide almost instant water heating, on-demand and in endless supply, but with a limited water flow rate.

With savings of over 60% and an environmentally friendly design, Titan products are an excellent choice for budget-friendly families and homeowners looking for advanced features. Built simple and with fewer components, Titan tankless products are not expensive and do not have high operating costs. They can use all the energy just for water heating, are almost maintenance-free, and do not rupture since there is no storage tank.

Hot water is always fresh due to the on-demand operation and endless supply. The most popular model, such as the SCR2, utilizes the digital microprocessor providing high efficiency and temperature stability. Depending on the model size, Titan can be used in small and larger homes, apartments, offices, hospitals, restaurants, boats...
