Heating and ventilation in bathroom

Abstract

At the end it is very inexpensive. The yearly cost is only 3 dollars per year.

1 . My HEATING AND VENTILATION IN BATHROOM system solves problems which occur in every bathroom or any space with a lot of moisture, it eliminates mold and mildew, supplies dry, warm air, is cost effective (˜3 dollars per year), consists of just few element such as;
 Axial fan, fan guard, flexible armored steel conduit, flexible metal conduit (FMC), Rigid Type C conduit body, fuse holder case, AMP fuse, fan speed control, or Single-Pole switch ON and OFF. 
 
     
     
         2 . The surprisingly quiet Axial fan, installed permanently over a door, is running non-stop, and its electrical wires are connected to Rigid Type C conduit body. 
     
     
         3 . The metallic armored steel flexible conduit with three wires Hot (L1), Neutral (N), Ground (G) are connected inside Rigid Type C and placed inside an electrical box ( 1900 ) on the other end. 
     
     
         4 . Inside the electrical box the L1 wire is connected to fan's speed control slider switch, neutral wire to the neutral wire and ground (green) to a ground wire. 
     
     
         5 . The main power L1 is connected to a fuse holder and from the fuse to fan's speed control slider switch. 
     
     
         6 . The whole electrical wiring and components are protected by time-delay ¼ AMP, 115 VAC fuse which is located in the fuse holder case. 
     
     
         7 . My idea improves positively air condition in a bathroom and when a chimney and axial fans run together the air recirculates 100% in 7 minutes (for example in 350 cubic feet bathroom), and mirror would never get foggy.
