Ariston Thermo’s AURES Instant Water Heater equipped with Constant Temperature (CT) technology is the first water heater in Singapore to be officially certified by PSB Singapore to be energy saving, with utility savings of at least 16.4%.

Ariston CT Technology

In 2016, Ariston was the first in the World to launch its series of instant water heaters with CT technology. These models are equipped with flow sensor (or flow switch), a series of Negative Temperature Coefficient (NTC) sensors and TRIAC. These sensors allow the heater to measure the temperature and flow of the water entering the water heater, and with TRIAC, the heater is able to adjust the power of the heating.

Utility-saving water heater, certified by PSB Singapore

PSB Singapore carried out the test based on a 10-minute shower process between a normal water heater (IM-3323) and a water heater with Ariston CT technology (SMC33).

During the test, there were interruptions to the water flow rate. This simulates real life incidences whereby there are other water usages in the home i.e. someone turning on the tap elsewhere in the house, or flushing the toilet bowl when the shower is going on.

Anti-Scalding feature by Ariston models with CT technology

The test also shows that for the model SMC33, with the temperature setting at a position when the outlet temperature is 37°C, the triangle icon on the front panel will start blinking when the inlet temperature reaches 40°C and above. The test also shows that the current cuts-off when the inlet temperature reaches 40°C. Therefore, with this anti-scalding feature, Ariston models with CT technology is safe for child-use.

The test does not take into consideration the time spent by users to adjust the shower temperature when there are changes to their shower temperature due to changes in water flow rate, which often happens to a normal user. Taking this into consideration, even more energy and water will be wasted in the process.

“At Ariston, we believe in offering high quality, energy efficient products that have limited impact on the environment. Our users deserve only the best in comfort. With the increase in utility bills in Singapore, we are also hoping that our technology will be able to help our users save water and energy through their daily use of water heaters.” Says Mr. Richard Chua, Director of South East Pacific, Ariston Thermo.
