Series R1K/B ideal for connection with an external boiler/solar. The wall-mounted boiler of the R1K/B series comes with a pre-installed temperature sensor with an 8m cable so that the boiler of our choice can be integrated into the digital control of the boiler. The temperature selection in the boiler is done from the DIGITECH® SYSTEM on the boiler. The boiler maintains this temperature constant within the boiler, achieving significant savings. Once a week, the boiler raises the temperature in the boiler to 70°C for its disinfection (Anti-Legionella function).

Since 1959, Radiant has been designing and manufacturing the main components of all its products. The technological advancements aimed at greater energy efficiency and reliability are 100% ensured by the made-in-Radiant wall-mounted boiler. The ONE-TECH® condensing heat exchanger, manufactured by Radiant, features wide-section coils made from a single INOX Ø 28 mm tube, thus ensuring higher thermal efficiency.

The DIGITECH® SYSTEM displays the temperatures and functions of the boiler in the most user-friendly and readable way. It allows for the precise adjustment of the desired temperature by degree for economy. It has the capability to control external sensors, solar panels, sensors for external boilers, autonomy valves, and a multitude of additional accessories.

The hydraulic connection of the closed expansion tank is at the top point to facilitate its replacement. The transformer is not part of the control board, resulting in easy, quick, and very low-cost replacement. All components are connected with brass fittings, making their repair easy.
