Company information
At the "Osaki Industrial Fair 2025" held on October 17th (Friday) and 18th (Saturday) of Reiwa Year 7, we were fortunate to connect with many people. Thank you to everyone who attended. ☆☆☆☆★☆☆☆☆★☆☆☆☆★☆☆☆☆★☆☆☆☆ As the general agent for floor heating systems and snow melting systems, we respond to a variety of needs not only in general residences across Tohoku but also in welfare facilities and public institutions, with the latest system variations and comprehensive total support. You can experience comfortable warmth from the morning with heat stored overnight. The "storage-type floor heating system," which utilizes nighttime electricity, is economical and represents the ideal system of having a cool head and warm feet. Since it does not use any open flames indoors and does not require space for heating equipment, it is perfect for nurseries, kindergartens, and welfare facilities.
