FAQ
Frequently asked questions

A nursing hospital cut heating cost by 71%, saving KRW 26 million over five winter months. A Gochang eel farm cut energy cost 70% after switching from Bunker C oil, and a swimming pool recorded 70% less power than an electric boiler. Savings depend heavily on the previous equipment.
Do you have cases in my sector?
As of 2026 around 100 sites are covered, including hotels and lodging, swimming pools and water parks, nursing hospitals, dormitories, industrial plants, food processing, fish farms and barns, saunas, public sports centres, religious facilities and solar homes. Tell us your sector and we will send comparable cases.
Can you supply public institutions?
Yes. The company is registered with the Public Procurement Service and has delivered to the Busan City public institution testbed project, Seo-gu Songdo Sports Centre and the WTC Seoul testbed project.
Can installation happen while we stay open?
Usually yes. Existing piping is reused and no outdoor unit or flue work is needed, so a typical site is finished in one to three days. Hotels and pools operating around the clock are handled by sequential floor-by-floor or zone-by-zone installation.
