空(kong)(kong)(kong)氣加(jia)熱(re)器(qi)中的電熱(re)體有電熱(re)線卷或電熱(re)絲與(yu)石棉織成的織品，另有鼓風(feng)機(ji)吹送(song)空(kong)(kong)(kong)氣經過電熱(re)體，由此空(kong)(kong)(kong)氣迅速加(jia)熱(re)。在室內循環，使(shi)用分隔磁極電動機(ji)驅動鼓風(feng)機(ji)。

    儲熱(re)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)爐中(zhong)(zhong)的(de)有(you)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)管(guan)或(huo)塊(kuai)狀(zhuang)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)體，產生的(de)熱(re)儲存與礦物(wu)的(de)或(huo)陶(tao)瓷的(de)物(wu)體中(zhong)(zhong)。儲熱(re)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)爐可利(li)用價廉的(de)夜間電(dian)(dian)(dian)(dian)(dian)(dian)流加熱(re)，再(zai)需(xu)要熱(re)量(liang)時使用鼓風機將儲熱(re)物(wu)體中(zhong)(zhong)的(de)熱(re)穿出暖(nuan)(nuan)室。地(di)板(ban)暖(nuan)(nuan)爐的(de)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)體成為電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)形狀(zhuang)置入(ru)與地(di)板(ban)中(zhong)(zhong)，房頂暖(nuan)(nuan)爐及墻壁暖(nuan)(nuan)爐有(you)相似的(de)構造。輻射(she)(she)(she)暖(nuan)(nuan)爐（紅外線輻射(she)(she)(she)器）有(you)管(guan)狀(zhuang)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)體，大多使用金屬(shu)管(guan)，用石英(ying)管(guan)較鮮。彎曲的(de)管(guan)狀(zhuang)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)體使用與墻壁輻射(she)(she)(she)暖(nuan)(nuan)爐。直(zhi)行管(guan)狀(zhuang)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)體使用于(yu)直(zhi)線，長路，及工業(ye)用等(deng)輻射(she)(she)(she)暖(nuan)(nuan)氣機中(zhong)(zhong)。

    輻射暖(nuan)爐應離開可(ke)燃物(wu)質有足夠的距離。
