Inspirational 40++ Forced Air Electric Heater
Inspirational 40++ Forced Air Electric Heater. Function on propane gas(lpg) 3. This forced air heating system from dura heat uses kerosene to get it working and to ensure the optimal temperature the electric cord is too short, so an extension cord is necessary for you to use this unit. When electricity is sent through materials like tungsten or graphite (heating elements in most electric heaters are a polymer blend of these), it excites the material in a resistive manner, the excess energy shed as powerful heat.
