1、冷熱(re)(re)水(shui)管(guan)(guan)主(zhu)要是以(yi)PPR水(shui)管(guan)(guan)為主(zhu)，既可(ke)作冷水(shui)管(guan)(guan)也可(ke)作熱(re)(re)水(shui)管(guan)(guan)，無毒耐(nai)壓耐(nai)腐(fu)蝕。冷水(shui)管(guan)(guan)一(yi)般(ban)外(wai)面會有藍色(se)標(biao)(biao)記的(de)直線(xian)，熱(re)(re)水(shui)管(guan)(guan)則是外(wai)面有紅色(se)線(xian)標(biao)(biao)記的(de)管(guan)(guan)材，材料(liao)及價格會有些微區分，不(bu)要弄(nong)錯了。

2、飲用(yong)水(shui)(shui)管(guan)需不結垢不生銹、具有環保安全抗菌性，因此一般(ban)以PE管(guan)、PPR管(guan)為主(zhu)。PE給(gei)水(shui)(shui)管(guan)一般(ban)只(zhi)做冷水(shui)(shui)管(guan)，而PPR管(guan)可做冷熱水(shui)(shui)管(guan)。在裝(zhuang)修(xiu)中(zhong)可兩種管(guan)材搭配使用(yong)。

3、家用排(pai)(pai)水管道、下水管對管道材(cai)(cai)質(zhi)的(de)要(yao)求不是(shi)(shi)很高(gao)，通常(chang)是(shi)(shi)以(yi)UPVC排(pai)(pai)水管為主，其耐化學腐蝕，抗沖強度(du)高(gao)，耐老化，使(shi)用壽命長，使(shi)用年限不低于50年，是(shi)(shi)建筑給(gei)排(pai)(pai)水的(de)理想材(cai)(cai)料。

4、電(dian)(dian)路是家(jia)裝(zhuang)(zhuang)裝(zhuang)(zhuang)修中的重要環節，暗線(xian)(xian)(xian)(xian)在(zai)墻(qiang)內，明線(xian)(xian)(xian)(xian)則在(zai)墻(qiang)上。由于家(jia)裝(zhuang)(zhuang)電(dian)(dian)路眾多，可(ke)用(yong)(yong)電(dian)(dian)線(xian)(xian)(xian)(xian)管，可(ke)以保護(hu)線(xian)(xian)(xian)(xian)纜，方便今后的維(wei)護(hu)，一般選用(yong)(yong)PVC線(xian)(xian)(xian)(xian)管，絕緣性能好、阻燃(ran)防火、耐熱抗(kang)壓(ya)。

5、地(di)(di)(di)(di)暖(nuan)(nuan)管(guan)分水地(di)(di)(di)(di)暖(nuan)(nuan)和電(dian)地(di)(di)(di)(di)暖(nuan)(nuan)，水地(di)(di)(di)(di)暖(nuan)(nuan)，是(shi)以溫度不高(gao)于(yu)(yu)60℃的熱(re)(re)水埋于(yu)(yu)地(di)(di)(di)(di)下(xia)填充層中的加(jia)(jia)熱(re)(re)管(guan)內循環(huan)流動，惻然(ran)加(jia)(jia)熱(re)(re)整個地(di)(di)(di)(di)板(ban)；而(er)電(dian)地(di)(di)(di)(di)暖(nuan)(nuan)是(shi)將(jiang)外(wai)表面允許工作溫度上限為(wei)65℃的發(fa)熱(re)(re)電(dian)纜(lan)埋設(she)在地(di)(di)(di)(di)板(ban)中，以發(fa)熱(re)(re)電(dian)纜(lan)為(wei)熱(re)(re)源加(jia)(jia)熱(re)(re)地(di)(di)(di)(di)板(ban)。通常比(bi)較常見的水地(di)(di)(di)(di)暖(nuan)(nuan)管(guan)以PERT管(guan)材為(wei)主，而(er)電(dian)地(di)(di)(di)(di)暖(nuan)(nuan)則采(cai)用(yong)發(fa)熱(re)(re)電(dian)纜(lan)。
