DIY Installation
IRSAP NOW Smart Valves are compatible with all major valve manufacturers and can be easily installed independently. With the help of our installation guides you can install your valves yourself.
Open window detection
The Smart Valve has sensors that can detect when a window is open. When this happens, the valve deactivates the radiator it is installed on for a pre-set period of time and thus limits energy consumption.
Advanced algorithms
Our Valves are really smart. Regulating algorithms, developed by IRSAP in their laboratories and the result of over 50 years of experience in making radiators, are able to learn from your habits and help you save energy.
Manual block
IRSAP has children’s safety at heart. You can therefore block the Smart Thermostatic Valves from being altered manually.
Anti-freeze Protection
Away from home for long periods? Choose Holiday Mode and the Smart Thermostatic Valves will set to the anti-freeze temperature. No more unpleasant surprises when you come home.
In-app Notifications
You always have everything under control. If there is a fault or if the batteries in your Smart Valves are flat, the system will notify you on your smartphone.
Saving immediately
By installing IRSAP NOW Smart Valves on your radiators you can decide right away how much to use your radiators and save money.
