Save on energy consumption with IRSAP NOW

Discover IRSAP NOW green technology and optimise energy consumption.

The impact of heating on consumption and environment

Home heating has a significant impact on each family’s total energy consumption and is one of the main factors responsible for producing air pollution emissions, with a consequent deterioration in air quality, especially during the winter months.

Find out how IRSAP NOW can help you reduce energy consumption and contribute to protecting the planet for your well-being and that of future generations.

The IRSAP NOW algorithms that help you save

Advanced IRSAP algorithms, the result of over 50 years of experience in the heating sector, are able to learn from your habits and help you to save energy, as well as keeping the use of your system under control.

Four modes of use

Choose one of the four modes designed by IRSAP NOW to adapt to your daily routine, providing comfort and saving.


Home/Away Mode

Going out unexpectedly? Change mode manually with the home / away keys or automatically depending on where you are.


Holiday Mode

Long periods away from home? Holiday Mode sets the entire system to anti-freeze temperature: less consumption and zero surprises when you return.


Performance Mode

Do you want maximum comfort? In this mode, heating turns on in advance, at the correct time, so you will find you home at the right temperature.


Eco Mode

Do you want to achieve maximum saving? Eco Mode is for you: the system continues to follow your habits but will turn off earlier than the time you set, thus reducing consumption and emissions.

Do you already have IRSAP radiators in your home?


The calculation is made considering the presence of the complete NOW system (smart thermostat and smart thermostatic valves) and an average heating use of 5 hours a day for 180 days a year. For homes over 300 square meters, the calculation is based on 300 square meters, the increase in size leads to an increase in potential energy savings. The cost of energy supply is updated to the last quarter of 2020, and includes national taxes. According to a study carried out by the University of Bergamo, the transition from traditional mechanical valves to the complete NOW system results in an energy saving of 42%. An additional 5% of energy savings can be achieved with the combination with IRSAP radiators, as the advanced control algorithm has been developed on our products.
