MUT SELECTION
Read full descriptionHide full description
We are pleased to present the new MUT SELECTION application, which makes the useful MUT Handbook on the best MUT products for heat pump installations and hybrid systems available. This mobile app has been designed to offer a simple and intuitive user experience, allowing customers to choose the appropriate MUT product based on the 3 thermal power ranges of the Heat Pump: 4-8 kWt, 11-16 kWt, 17-26 kWt. Once the thermal power size is selected, the app will display all the recommended MUT products for that power size*. For each product, it will be possible to read a detailed description, learn about the benefits of using it, and download the technical data sheet. Moreover, if further information is desired, it will be possible to contact our customer service through the app. MUT SELECTION is a practical and convenient solution to learn about the most suitable MUT products for one's needs. *Note: The sizing and verification within the specifications of a project must be verified/performed by an authorized technical designer in compliance with mandatory regulations.
