Since  1959, Radiant has been designing and manufacturing  the main components of all its products in its own facilities in central Italy. Technological developments aimed at  greater energy efficiency and reliability  are 100% guaranteed by the made in Radiant wall-mounted boiler.

The COMBI-TECH® condensing exchanger  , manufactured by Radiant, features wide-section coils made of a single Ø 28 mm INOX  tube  , thus ensuring higher thermal efficiency, lower thermal load losses and facilitating maintenance work.

60+ years  of experience  provide Radiant with the necessary  know-how  to design and manufacture the exchanger with which the R 2K RAIN series condensing boilers are equipped.

UNCOMPROMISING TIMELESS QUALITY:
100% made in Radiant
100% made in Italy

Silent Operation.
The combination of front and perimeter thermal and acoustic insulation , the  sound-absorbing funnel  and the  newly designed air/gas mixer ensure that the boiler has extremely low noise levels ( <52dB at 100% of its operation ) both during ignition and during its operation.

Great Strength.

The use of the INOX exchanger , the  copper pipes  , the  brass  mechanical tightening fittings and the individual high-quality components provide a homogeneous whole that contributes to the  uninterrupted operation of the boiler  and  its durability over time .

THE CONSTRUCTION DETAILS THAT MAKE THE DIFFERENCE

The components  of the wall-mounted boiler are arranged in such a way that they are all  easily accessible, for their inspection  and any repairs that may occur, e.g.

  • The  closed expansion tank  is on the side with the valve in front, for easy maintenance.
  • The hydraulic connection of the closed expansion tank is at the top so that it can be easily replaced.
  • The transformer  is not part of the management board, making its replacement easy, quick and very cost-effective, unlike replacing the board that has the transformer integrated, which is a time-consuming and costly process.
  • All components are connected with  brass fittings  , making them easy to repair.
  • The special  sound-absorbing funnel  helps reduce noise.
  • all  components  are made of branded  high quality  materials, e.g. Callefi.
Spare Parts Warehouse.
The large inventory of spare parts  and  their low prices  ensure the trouble-free operation of your boiler and your prompt service for  many years .
Top Quality.
All branded boiler components  are connected to copper pipes and their connections are made with brass fittings to ensure maximum  tightness and durability  of the boiler.
