Our home heating system based on our unique technology and invention (Pat. No. 0387377, PCT/KR2005/002568) enables us to save energy from 40% up to 70%. We are using electricity for Smart Heater(Portable Electric Home Heater) and either hot water or steam for Retrofit as heat sources.

Retrofit for either hot water or steam will have the same heating panel as on Smart Heater with single pipe, instead of electrical device, at the bottom of the heating panel for passage of either hot water or steam. You can easily install our Retrofit at home, using the connectors at both ends of the passage pipe. For detailed information, please visit our web site www.korsun.co.kr at your earliest convenience.
