  • There is no need for a separate boiler and there is almost no heat loss as heating and heat dissipation are performed directly in the heating place.
  • There is no worry of freezing or breaking in winter, and since the structure is simple, there is little breakdown.
  • Since there is no mechanical device, there is no balance and no separate maintenance is required, which is convenient.
  • It is very convenient to use due to the adoption of the advanced indoor temperature controller and does not require replenishment of fuel.
  • The heat dissipation amount can be properly controlled with a temperature controller, making it efficient and convenient to use.
  • Since it uses electricity, which is clean energy, there is no odor or smoke, and there is no risk of explosion, gas poisoning, or fire.
  • Since it is produced according to the application site, it is easy to install, and it is economical because the weak durability and insufficiency of the simple facility products such as panels are completely compensated.
