The Power-Tech series, including the R1K50, R1K75, and R1K100 models, all feature Combi-Tech heat exchangers manufactured entirely by Radiant.
The R1K75 and R1K100 models consist of 2 boilers within a single boiler body. This design provides space-saving benefits to consumers with a width of 70cm. They are designed with power outputs of 75kW (50+25kW) and 100kW (50+50kW) respectively.
The innovative solutions offer advantages in terms of performance and safety. For example, the 1:20 modulation (75 and 100kW) allows for the activation of only one boiler based on demand or the ability to switch to the other boiler in case of a breakdown, ensuring uninterrupted service of our system.
