Heating and hot water supply with an integrated Boiler.

COMBINED OPERATION WITH 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, along with the preheating function of the hot water supply, is crucial for the success of the R2KA model. This is how the DUAL-TECH® system is born, ensuring the smooth operation of the boiler without temperature fluctuations during hot water production even with high flow rates.

COMBI-TECH®

The revolution in heat exchangers. The COMBI-TECH® condensing exchanger, manufactured by Radiant, features wide-section coils made from a single INOX pipe Ø 28 mm, ensuring higher thermal efficiency and lower thermal load losses.

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

DIGITECH® SYSTEM

Simply ingenious. The DIGITECH® SYSTEM displays the temperatures and functions of the boiler in the most user-friendly and readable way with large letters and icons. It allows for precise adjustment of the desired temperature for economy.

CONSTRUCTION DETAILS THAT MAKE THE DIFFERENCE:

• All components of the wall-mounted boiler are arranged for easy access.
• The hydraulic connection of the closed expansion tank is at the top for easy replacement.
• All components are connected with brass fittings for easy repair.
• The special sound-absorbing hood helps reduce noise.
• All components are made from high-quality branded materials.

EASIER MAINTENANCE: Wide-section INOX coils Ø 28 mm for minimal clogging chances.

DUAL-TECH SYSTEM: Uses an intelligent method for preheating the hot water supply.

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

Specifications:

• Nominal thermal power (Max) kW: 28
• Nominal thermal power (Min) kW: 3.7
