1、冷熱(re)(re)水(shui)管(guan)(guan)(guan)主要是以PPR水(shui)管(guan)(guan)(guan)為主，既可(ke)(ke)作(zuo)冷水(shui)管(guan)(guan)(guan)也可(ke)(ke)作(zuo)熱(re)(re)水(shui)管(guan)(guan)(guan)，無毒耐壓(ya)耐腐蝕。冷水(shui)管(guan)(guan)(guan)一般外(wai)面會(hui)有(you)(you)藍色(se)標(biao)記的(de)直線，熱(re)(re)水(shui)管(guan)(guan)(guan)則(ze)是外(wai)面有(you)(you)紅(hong)色(se)線標(biao)記的(de)管(guan)(guan)(guan)材，材料及價(jia)格會(hui)有(you)(you)些微區分，不要弄(nong)錯了。

2、飲用(yong)水(shui)管(guan)(guan)(guan)需不結垢不生銹、具有環保(bao)安(an)全抗菌性，因(yin)此一般(ban)以(yi)PE管(guan)(guan)(guan)、PPR管(guan)(guan)(guan)為主。PE給水(shui)管(guan)(guan)(guan)一般(ban)只做冷(leng)水(shui)管(guan)(guan)(guan)，而PPR管(guan)(guan)(guan)可(ke)做冷(leng)熱水(shui)管(guan)(guan)(guan)。在(zai)裝修中可(ke)兩種管(guan)(guan)(guan)材(cai)搭配使用(yong)。

3、家用(yong)排(pai)(pai)水管道、下水管對管道材(cai)質(zhi)的要(yao)求不是很高，通常(chang)是以UPVC排(pai)(pai)水管為主，其耐化(hua)學(xue)腐蝕，抗沖強度高，耐老化(hua)，使用(yong)壽命(ming)長，使用(yong)年(nian)限(xian)不低于50年(nian)，是建筑給排(pai)(pai)水的理想材(cai)料。

4、電路是(shi)家裝裝修中的(de)重(zhong)要環節，暗線(xian)在墻內(nei)，明線(xian)則在墻上(shang)。由于家裝電路眾(zhong)多，可用(yong)電線(xian)管(guan)，可以(yi)保護(hu)線(xian)纜，方(fang)便(bian)今(jin)后的(de)維護(hu)，一般選用(yong)PVC線(xian)管(guan)，絕緣(yuan)性能(neng)好、阻(zu)燃防火、耐(nai)熱(re)抗(kang)壓(ya)。

5、地(di)(di)(di)(di)暖(nuan)(nuan)管分水地(di)(di)(di)(di)暖(nuan)(nuan)和電地(di)(di)(di)(di)暖(nuan)(nuan)，水地(di)(di)(di)(di)暖(nuan)(nuan)，是以(yi)溫度不高于60℃的(de)熱(re)(re)水埋于地(di)(di)(di)(di)下填充(chong)層中(zhong)(zhong)的(de)加(jia)(jia)熱(re)(re)管內循環流動(dong)，惻然加(jia)(jia)熱(re)(re)整個地(di)(di)(di)(di)板(ban)；而電地(di)(di)(di)(di)暖(nuan)(nuan)是將外(wai)表面允許工作溫度上(shang)限為(wei)65℃的(de)發熱(re)(re)電纜埋設(she)在(zai)地(di)(di)(di)(di)板(ban)中(zhong)(zhong)，以(yi)發熱(re)(re)電纜為(wei)熱(re)(re)源(yuan)加(jia)(jia)熱(re)(re)地(di)(di)(di)(di)板(ban)。通常比(bi)較(jiao)常見的(de)水地(di)(di)(di)(di)暖(nuan)(nuan)管以(yi)PERT管材為(wei)主，而電地(di)(di)(di)(di)暖(nuan)(nuan)則采用發熱(re)(re)電纜。
