1、冷(leng)(leng)熱水(shui)(shui)管(guan)主(zhu)(zhu)要(yao)是(shi)以PPR水(shui)(shui)管(guan)為主(zhu)(zhu)，既可作冷(leng)(leng)水(shui)(shui)管(guan)也可作熱水(shui)(shui)管(guan)，無(wu)毒耐壓耐腐(fu)蝕。冷(leng)(leng)水(shui)(shui)管(guan)一般外面(mian)會有藍色標記的直(zhi)線，熱水(shui)(shui)管(guan)則是(shi)外面(mian)有紅色線標記的管(guan)材(cai)，材(cai)料及價格會有些微(wei)區(qu)分，不要(yao)弄錯了。

2、飲用(yong)水(shui)(shui)管需(xu)不結垢不生銹、具有環保(bao)安全抗菌性，因(yin)此一般以PE管、PPR管為主(zhu)。PE給水(shui)(shui)管一般只做冷水(shui)(shui)管，而PPR管可做冷熱水(shui)(shui)管。在裝修中可兩種管材(cai)搭配使用(yong)。

3、家(jia)用(yong)排(pai)水(shui)管(guan)(guan)道、下水(shui)管(guan)(guan)對管(guan)(guan)道材質(zhi)的要(yao)求不是(shi)很高(gao)，通(tong)常(chang)是(shi)以UPVC排(pai)水(shui)管(guan)(guan)為(wei)主，其耐(nai)化學腐蝕，抗沖(chong)強度高(gao)，耐(nai)老化，使用(yong)壽命長，使用(yong)年限不低于50年，是(shi)建筑(zhu)給排(pai)水(shui)的理想材料。

4、電路是家裝(zhuang)(zhuang)裝(zhuang)(zhuang)修(xiu)中的重要環節(jie)，暗線(xian)在墻(qiang)內(nei)，明線(xian)則在墻(qiang)上。由于家裝(zhuang)(zhuang)電路眾多(duo)，可用(yong)電線(xian)管，可以保(bao)護線(xian)纜，方便今后的維(wei)護，一般選用(yong)PVC線(xian)管，絕緣性能好(hao)、阻燃防火、耐熱抗(kang)壓。

5、地(di)(di)(di)(di)(di)暖(nuan)(nuan)管(guan)分水(shui)地(di)(di)(di)(di)(di)暖(nuan)(nuan)和電(dian)(dian)地(di)(di)(di)(di)(di)暖(nuan)(nuan)，水(shui)地(di)(di)(di)(di)(di)暖(nuan)(nuan)，是(shi)以溫度不(bu)高(gao)于60℃的(de)熱(re)(re)水(shui)埋于地(di)(di)(di)(di)(di)下填充層中(zhong)的(de)加熱(re)(re)管(guan)內循環(huan)流動(dong)，惻(ce)然加熱(re)(re)整個地(di)(di)(di)(di)(di)板(ban)；而電(dian)(dian)地(di)(di)(di)(di)(di)暖(nuan)(nuan)是(shi)將外表面(mian)允許工作溫度上(shang)限為(wei)65℃的(de)發熱(re)(re)電(dian)(dian)纜埋設在地(di)(di)(di)(di)(di)板(ban)中(zhong)，以發熱(re)(re)電(dian)(dian)纜為(wei)熱(re)(re)源加熱(re)(re)地(di)(di)(di)(di)(di)板(ban)。通(tong)常比較常見的(de)水(shui)地(di)(di)(di)(di)(di)暖(nuan)(nuan)管(guan)以PERT管(guan)材為(wei)主，而電(dian)(dian)地(di)(di)(di)(di)(di)暖(nuan)(nuan)則采用發熱(re)(re)電(dian)(dian)纜。
