Green Way Regenerative Fan Heater uses midnight electric power that is much cheaper than general electricity. It converts electricity into heat, keeps it in the regenerative system, and uses during daytime. The latest heating system, it is economical enough to save electric rates by a quarter.

 
   
Clean heating
It uses electricity as fuel so it doesnt make smoke. Accordingly it is clean compared with other heating systems.
Safe heating
It is safe, having no phenomenon of lack of oxygen or no danger of explosion.
Economical heating
A thermostat makes it possible to control the temperature of each room so there is no unnecessary fuel consumption.
Convenient heating
It doesnt need space to keep fuel so it is installable even in small space.
Environmental pollution-free heating
It doesnt cause lack of oxygen, dusts, or smell, and it doesnt contaminate air. Therefore, it is harmless to the human body.
Uses
It is available for living rooms, bedrooms, or study rooms for students at home. It is very suitable for heating offices, officetels, schools, hospitals, and other working areas. It is very suitable, especially for repairing old heating systems in buildings.
