The R1K ONE TECH Rain Gas Boiler Series by Radiant, designed for outdoor installation, features a modern aesthetic, high energy efficiency, and a robust construction. It provides seamless and efficient long-lasting operation.

In a nutshell, the boiler:

• High-quality casing: The outer shell of the boiler is made from high-quality plastic, fully protecting the boiler from weather conditions.
• Sun resistance: The casing makes the boiler immune to UV rays from the sun.
• Protection grade IPX5D: All RAIN boilers are designed to withstand the climatic conditions of coastal and inland areas.
• High durability: The use of stainless steel heat exchangers, copper piping, brass compression fittings, and other high-quality components create a cohesive unit that ensures smooth operation and long-term durability of the boiler.
• Quiet operation: The combination of front and perimeter thermal insulation, sound-absorbing hopper, and a new air/gas mixer design ensure the boiler operates at extremely low noise levels.

Radiant Expertise: Over 60 years of experience give Radiant the essential know-how for designing and manufacturing the heat exchangers used in the R 1K series condensing boilers.

Efficiency and reliability: Technological advancements aimed at greater energy efficiency and reliability are fully guaranteed by the made-in-Radiant wall-mounted boiler.

Compact dimensions: Its compact size allows installation in spaces with limited available area. Its simple yet modern design helps it to blend seamlessly into any setting.

Easy servicing: The components of the wall-mounted boiler are arranged for easy access, inspection, and repair if needed.

Spare parts stockpile: A large inventory of spare parts and their low prices ensure trouble-free operation of your boiler and prompt service for many years.

Top quality: All branded boiler components are connected with copper pipes, and their connections are made with brass fittings to maximize leak-tightness and durability of the boiler.

Ergonomic design: Its well-thought-out design allows for easy installation, handling, and access for maintenance and inspection during annual servicing of the gas boiler.

Ø28 Inox Heat Exchanger: Easier maintenance: wide-diameter INOX coils Ø 28 mm for minimal risk of clogging and therefore fewer interventions by the technician. Energy saving: a 1:9 ratio ideal for optimizing consumption even at minimal power, resulting in a significant reduction in operating costs.

Inverter Circulator: PWM INVERTER circulating pump: The pump adjusts its speed/flow based on the settings, increasing or decreasing as needed.

Flue Valve: Non-return valve: “Clapet” for easy connection to central exhaust systems. Complete flue blockage: after the boiler's operation ends, the acquired heat is trapped within the heat exchanger and not expelled.
