Components of Hoya Hydronic Floor Heating System

Hoya Elvan Stone Panels

Our Hoya ondol panels are made from carbon mineral with elvan stone. Elvan stone radiates a large amount of beneficial infrared rays, when it is heated. Infrared rays assist in healing cold and respiratory related illnesses, reduce airborne bacteria, and have anti-aging effects. It improves ionization within the body to enhance cellular processes, blood circulation and metabolism. Our elvan stone panels give a firm support to the finished floor. The firm stone panels must eliminate your unpleasant experience with other hydronic heating systems.

Elvan Stone Floors

One of the main function of LVP underlayment is insulation that reduces thermal bridging between floor lays. Most of final floor materials, in our neighbor, have the insulation underlayment. However, hydronic floor heating system requires thermal conductivity to transfer heat from hot water to finished floor. We have desperately worked on this issue. Now we can facilitate our hydronic heating system with the new elvan stone SPC floor. Our elvan stone SPC flooring shall provide superior thermal conductivity, and maximize heating efficiency with our elvan stone panels.
