第一課：如何選擇采暖系統？
采暖(nuan)(nuan)(nuan)的(de)系(xi)(xi)(xi)統(tong)(tong)類型主要(yao)分為四種：地暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)、暖(nuan)(nuan)(nuan)氣(qi)片系(xi)(xi)(xi)統(tong)(tong)、地暖(nuan)(nuan)(nuan)+暖(nuan)(nuan)(nuan)氣(qi)片系(xi)(xi)(xi)統(tong)(tong)和(he)電(dian)暖(nuan)(nuan)(nuan)氣(qi)系(xi)(xi)(xi)統(tong)(tong)。四種系(xi)(xi)(xi)統(tong)(tong)各有(you)優缺點及適(shi)(shi)用性，沒有(you)哪種采暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)是(shi)完美無缺的(de)。所以(yi)，要(yao)選擇(ze)適(shi)(shi)合(he)自(zi)己(ji)的(de)采暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)，適(shi)(shi)合(he)的(de)即(ji)是(shi)最好(hao)的(de)。
第一節：地暖系(xi)統
第二節(jie)：暖氣片系(xi)統(tong)
第(di)三節：地暖+暖氣片系(xi)統(tong)
第四節：電暖(nuan)氣系統
