Around 2009 when the economy stared to do down hill ,home owner stared to look for cheap electric heaters
but regardless if its a cheap ” less expensive heater or higher end heater as a home owner you need to know some basics so here is a very detailed  Electric Heater Glossary read slow, but please read… Thank you !

Amps (Ampere)
The amount or current flowing through the wire,
Note: Amps and volts are not the same – voltage is pressure behind the current, the higher the pressure the higher the potential current.
Example: Think water out of standard garden hose, it has a nice constant flow of water; it will shot out the need a few inches. We have a low flow (current flow) do to low water pressure (voltage pressure like 120 volts)
Now a fire hose on the other hand has a higher flow do to a much higher water pressure.

AWG (American Wire Gauge)
This is a standardized electrical wire gauge system that we use in the US for the diameters of round.
0 AWG is a very large wire
12 & 14 AWG are common wires used in your home
16 AWG is used on most table lamps
30 AWG is Very small

Back Box (for wall heaters)
This is a metal mounting box that’s enclosed on 5 sides. The back box is mounted in the wall first then the rest of the heater is mounted inside the back box. Then the front grille covers box and the heater components.

Baseboard Heater – is a long and narrow heater without a fan. It’s mounted on the floor like baseboard molding. Baseboard heaters are convection heater only wider, warm air rises out the top and cold air is entrained through the bottom opening. It’s a good idea to place them the outside or cold wall near or below a window.

Bathroom Heaters – come in many styles and mounting configurations like, wall, ceiling, baseboard, infrared bulb heaters. The all work for deferent reasons. Fan forced wall & ceiling heaters heat very quickly. Baseboard heaters are silent, slow and stead room heaters. Bulb heaters put out an infrared heat that heats people and objects below the bulbs, not the air. Bulb heaters are only good as a secondary heater.

Bedroom Heaters – we define them has quiet or silent electric heaters without a fan. They can be baseboard, convection wall heater, cove heater pretty much any heater without fan noise.
