Rinnai Korea

What Rinnai Korea does

Rinnai Korea (린나이코리아㈜) is the Korean sales, marketing, and after-sales subsidiary of Japanese appliance manufacturer Rinnai Corporation, established in 1974 and headquartered in Incheon. The company sells premium residential gas and electric appliances — including water heaters, gas cooking appliances, home boilers, and electric ranges — through a hybrid distribution model combining an authorized dealer network with its own direct e-commerce platform (Rinnai Mall) and occasional pop-up retail activations such as the Starfield Hanam store. Its business model is fundamentally B2C hardware sales with a strong emphasis on installer relationships, after-sales service infrastructure, and brand-led premium pricing, leveraging the global Rinnai brand equity transferred from its Japanese parent.

Rinnai Korea holds the #1 position in the Korea Standard Premium Brand Index (KS-PBI) for electric ranges for 10 consecutive years and the #1 position in KS-SQI for home boiler after-sales service for 12 consecutive years, reflecting durable brand and service quality leadership in its core categories. The company also operates an AI-based chatbot and voicebot service in partnership with KT to scale customer support across its large installed base, despite operating with a lean team of approximately 14 employees. Recent strategic moves include launching the Rinnai Mall direct online channel, opening pop-up stores outside traditional dealer routes, and producing brand community content such as the Sakhalin Korean cooking class program. Leadership rests with President Cho Sang-hoon (조상훈); the entity's business registration is 137-81-00581, and no audited revenue figures are publicly disclosed.
