Heating and hot water supply with an integrated Boiler. Radiant has combined all the advantages of the R2K instantaneous production boilers with those of storage boilers.

• The use of the COMBI-TECH® exchanger with a double integrated wide-section coil Ø28 mm is crucial for the success of the R2KA model.

• The DUAL-TECH® system ensures the smooth operation of the boiler without temperature fluctuations during hot water production.

• Increases boiler efficiency by allowing condensation with efficiencies above 105%.

COMBI-TECH®: The revolution in heat exchangers. The COMBI-TECH® condensing exchanger, manufactured by Radiant, features wide-section coils made from a single INOX tube Ø28 mm, thus ensuring higher thermal performance.

DIGITECH® SYSTEM: Simple and user-friendly temperature adjustment per degree with high accuracy. Controls external sensors, solar panels, and many other additional components.

The construction details of the wall-mounted boiler are designed for easy access and repair.

• The components are made from branded high-quality materials.

Easier maintenance: wide-section INOX coils Ø28 mm for minimal clogging chances.

DUAL-TECH system: uses an intelligent preheating method for hot water supply for immediate restoration of hot water quantity.

INVERTER PUMP with PWM: the pump increases or decreases the speed/flow of water in the circuit.
