RadiatorCheck – planning tool for used radiators

RadiatorCheck was selected by the CBI Innovation Booster for their 2025 funding projects. With RadiatorCheck, the project team is developing an open-source app that makes it easy to estimate the heating output of used radiators. Dr Silvia Domingo Irigoyen from HSLU (Lucerne University of Applied Sciences and Arts) will develop a thermal model for calculating heating output. Ayra Tyce from the Overall component exchange brings many years of experience in dismantling, refurbishing and brokering used radiators to the project. Together with Alexander Schorfmann from Zirkular, they form the project team. 

Alexander has programmed a first prototype of the app. This has already been used in Zirkular’s projects to estimate the heating output of second-life radiators.

Whether a radiator is suitable for reinstalment  depends largely on its heating output. Until now, such assessments have been time-consuming and costly. RadiatorCheck aims to change that. With just a few inputs, the heating capacity can be determined and the replacement process made more efficient. 

Radiators are ideal for reuse, both ecologically and economically. RadiatorCheck aims to make this potential accessible to the circular economy, the app is open-source and tested in practice.
