家用暖氣片選購前的三項注意：

1、對(dui)于(yu)(yu)分(fen)戶供(gong)暖(nuan)(nuan)系統，現在可(ke)以更(geng)換暖(nuan)(nuan)氣片。而對(dui)于(yu)(yu)集中供(gong)暖(nuan)(nuan)系統，則不宜隨意更(geng)換。盲(mang)目追求美(mei)觀，很可(ke)能會(hui)對(dui)自家及左鄰右舍(she)的供(gong)暖(nuan)(nuan)，甚至人身安全造成(cheng)影響。如(ru)果一定要(yao)更(geng)換，必須由正規(gui)專業的人員操(cao)作。

2、在裝修(xiu)前和(he)供暖(nuan)(nuan)(nuan)前更換(huan)暖(nuan)(nuan)(nuan)氣片(pian)(pian)：更換(huan)暖(nuan)(nuan)(nuan)氣片(pian)(pian)好(hao)在非供暖(nuan)(nuan)(nuan)期(qi)。

目前北京多數小區仍采用集中(zhong)供(gong)(gong)暖(nuan)，因此，一(yi)旦(dan)進入供(gong)(gong)暖(nuan)期(qi)，更換暖(nuan)氣片勢必影響其他用戶的供(gong)(gong)暖(nuan)。而且這(zhe)樣做也存(cun)在(zai)(zai)一(yi)定不安(an)全因素。供(gong)(gong)暖(nuan)期(qi)間，暖(nuan)氣管道中(zhong)存(cun)在(zai)(zai)壓力(li)，若處理不當，已造成危險。

3、更換(huan)暖氣片，應在裝修前或(huo)剛剛開始裝修時

因為暖(nuan)氣片都(dou)是定(ding)制(zhi)產品，根據品牌不同，訂貨周(zhou)期在(zai)15天(tian)至30天(tian)。而且(qie)，在(zai)墻面(mian)裝修(xiu)前應(ying)將暖(nuan)氣拆(chai)下(xia)來，并根據新(xin)暖(nuan)氣尺寸定(ding)好相應(ying)位置。

選購家用暖氣片時需要注意的幾點：

1、了解小區供暖系統

有(you)些地(di)區(qu)供(gong)(gong)熱系(xi)統水(shui)質(zhi)不太好，城(cheng)市集中供(gong)(gong)熱的(de)方(fang)式也五(wu)花八門，有(you)集中供(gong)(gong)熱站(zhan)，有(you)家庭熱水(shui)中心，有(you)電(dian)廠等余熱供(gong)(gong)熱，有(you)開(kai)放式無(wu)壓鍋爐供(gong)(gong)熱，使得(de)城(cheng)市供(gong)(gong)熱熱水(shui)水(shui)質(zhi)差(cha)別(bie)很大，有(you)的(de)含氧(yang)量高，有(you)的(de)水(shui)質(zhi)偏酸性，有(you)的(de)水(shui)質(zhi)偏堿性。所以在購買(mai)暖氣片之(zhi)前，要向供(gong)(gong)熱單(dan)位(wei)或小區(qu)物管(guan)單(dan)位(wei)了解本小區(qu)的(de)供(gong)(gong)熱系(xi)統是什么(me)形式，根據其水(shui)質(zhi)特(te)點決(jue)定購買(mai)什么(me)材質(zhi)的(de)暖氣片。

一(yi)般(ban)來說，鋼制暖氣(qi)片(pian)，不(bu)能(neng)在(zai)開放式無壓(ya)鍋爐或蒸汽供熱(re)(re)系(xi)統中使用；鋁(lv)合(he)(he)金暖氣(qi)片(pian)，不(bu)能(neng)在(zai)水質PH值過(guo)大的供熱(re)(re)系(xi)統或蒸汽供熱(re)(re)系(xi)統中使用；銅管鋁(lv)翼(yi)片(pian)(銅鋁(lv)復合(he)(he))暖氣(qi)片(pian)對水質無特殊要求，但安裝使用時要注意(yi)避免使銅管與(yu)翼(yi)柱銅管的接口(kou)受(shou)到過(guo)大的扭力(li)。

其次，記錄(lu)原有暖氣片的大(da)小，盡量根據(ju)原暖氣片的散熱(re)量選擇暖氣片大(da)小；若無法獲得原散熱(re)量，則需根據(ju)自家房屋大(da)小、朝向、樓層(ceng)及窗戶大(da)小等因素(su)估算(suan)。

2、分清材質特性，按水質選用不同材質

新(xin)型家用暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)，按(an)材料的不同分為鋼(gang)制(zhi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、鋁(lv)合(he)金暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、銅(tong)制(zhi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、銅(tong)鋁(lv)復合(he)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、鋼(gang)鋁(lv)復合(he)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、不銹(xiu)鋼(gang)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)等；按(an)產品外形(xing)(xing)特點又分為柱(zhu)(zhu)式(shi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)(二柱(zhu)(zhu)、三柱(zhu)(zhu)、四柱(zhu)(zhu))、排(pai)(pai)(pai)(pai)管式(shi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)(單排(pai)(pai)(pai)(pai)管、雙排(pai)(pai)(pai)(pai)管)、翼(yi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)式(shi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)(雙面(mian)翼(yi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、單面(mian)翼(yi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian))、翅片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)式(shi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)(環形(xing)(xing)翅片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、方形(xing)(xing)翅片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian))，按(an)散熱方式(shi)分為輻射暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、對流式(shi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)等。常用的新(xin)型家用暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)是鋼(gang)制(zhi)柱(zhu)(zhu)式(shi)暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、鋼(gang)制(zhi)排(pai)(pai)(pai)(pai)管暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、鋁(lv)合(he)金柱(zhu)(zhu)翼(yi)型暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)、銅(tong)鋁(lv)復合(he)柱(zhu)(zhu)翼(yi)型暖(nuan)(nuan)(nuan)氣(qi)(qi)(qi)(qi)(qi)片(pian)(pian)(pian)(pian)(pian)(pian)(pian)(pian)。

由(you)于材料自(zi)身的特性，鋁(lv)合金(jin)(jin)耐酸(suan)、耐氧(yang)化(hua)，但易發(fa)生堿性腐(fu)蝕(shi)；鋼(gang)的強度高，能(neng)(neng)耐一定(ding)的堿性，但易發(fa)生氧(yang)化(hua)腐(fu)蝕(shi)；銅(tong)的耐腐(fu)蝕(shi)等綜合性能(neng)(neng)較好，但水中(zhong)硫化(hua)物過(guo)多或(huo)是(shi)雜銅(tong)也(ye)會腐(fu)蝕(shi)，且銅(tong)的機械強度偏低。國家要求鋁(lv)合金(jin)(jin)暖氣片和(he)壁厚(hou)在2。5mm以下的鋼(gang)制暖氣片，必須進行內(nei)防腐(fu)處理(li)，涂(tu)布內(nei)防腐(fu)涂(tu)層，且鋁(lv)合金(jin)(jin)暖氣片必須采用(yong)專用(yong)非金(jin)(jin)屬或(huo)雙金(jin)(jin)屬復合管(guan)(guan)件，不得使(shi)鋁(lv)制螺紋直接與鋼(gang)管(guan)(guan)連接，防止(zhi)電(dian)化(hua)學腐(fu)蝕(shi)。

專家(jia)建議，如(ru)果所居住的小(xiao)區為分(fen)戶供(gong)暖(nuan)(nuan)(nuan)，市場上的暖(nuan)(nuan)(nuan)氣(qi)片(pian)基本(ben)都可選用(yong)。若(ruo)為集中供(gong)暖(nuan)(nuan)(nuan)，則需根據小(xiao)區的水(shui)質來做(zuo)選擇，比如(ru)，水(shui)質含堿量高(gao)就(jiu)不宜(yi)采用(yong)鋁(lv)(lv)質暖(nuan)(nuan)(nuan)氣(qi)片(pian)，宜(yi)選用(yong)鋼制暖(nuan)(nuan)(nuan)氣(qi)片(pian)。而水(shui)中含氧量較大(da)，就(jiu)不宜(yi)選用(yong)鋼質的，宜(yi)選用(yong)內層(ceng)做(zuo)過防腐處理的鋼制暖(nuan)(nuan)(nuan)氣(qi)片(pian)或者是鋁(lv)(lv)質暖(nuan)(nuan)(nuan)氣(qi)片(pian)等。一般情況(kuang)下(xia)銅鋁(lv)(lv)復合和新型鑄鐵的對水(shui)質要求不嚴。另外，各個房間所用(yong)暖(nuan)(nuan)(nuan)氣(qi)片(pian)材質好是相同或相近(jin)的，以(yi)避免由于不同材質之(zhi)間產(chan)生電化(hua)學反應(ying)而腐蝕。

3、注意焊接質量

暖(nuan)氣(qi)(qi)片的(de)(de)(de)不(bu)(bu)同部分是用(yong)焊(han)(han)(han)接連接，焊(han)(han)(han)接質量(liang)的(de)(de)(de)好壞直接影響暖(nuan)氣(qi)(qi)片的(de)(de)(de)質量(liang)和使用(yong)壽命。焊(han)(han)(han)接工藝主(zhu)(zhu)要有填(tian)充物焊(han)(han)(han)和本體焊(han)(han)(han)，相(xiang)對而(er)言，本體焊(han)(han)(han)的(de)(de)(de)耐腐蝕性(xing)好，且有一道(dao)均勻焊(han)(han)(han)疤，不(bu)(bu)需打(da)磨(mo)；填(tian)充物焊(han)(han)(han)的(de)(de)(de)耐腐蝕性(xing)差，表面經打(da)磨(mo)光滑平(ping)(ping)整(zheng)。消費者在購買時主(zhu)(zhu)要看其焊(han)(han)(han)接是否(fou)牢(lao)固(gu)、外觀焊(han)(han)(han)縫是否(fou)均勻，有沒有凹凸(tu)不(bu)(bu)平(ping)(ping)的(de)(de)(de)現象。但是，不(bu)(bu)可過于強求(qiu)焊(han)(han)(han)縫的(de)(de)(de)光滑平(ping)(ping)整(zheng)，因(yin)為過度(du)的(de)(de)(de)打(da)磨(mo)處理容易(yi)造成焊(han)(han)(han)接部位的(de)(de)(de)強度(du)降低，導致跑漏水。

4、選用優質配件

暖氣片(pian)零配(pei)件質(zhi)量(liang)問(wen)題及安裝材料質(zhi)量(liang)問(wen)題是導致暖氣漏(lou)水的主要原因之一，應該到正規市(shi)場選(xuan)用國家優(you)質(zhi)水暖配(pei)件。

鋁(lv)(lv)(lv)塑復(fu)合管一(yi)(yi)般(ban)是暖氣片所(suo)用到的管材，鋁(lv)(lv)(lv)塑復(fu)合管的鋁(lv)(lv)(lv)層(ceng)接(jie)(jie)(jie)(jie)(jie)頭有搭(da)接(jie)(jie)(jie)(jie)(jie)和對(dui)(dui)接(jie)(jie)(jie)(jie)(jie)兩種(zhong)，搭(da)接(jie)(jie)(jie)(jie)(jie)的一(yi)(yi)般(ban)優于對(dui)(dui)接(jie)(jie)(jie)(jie)(jie)的，因(yin)為對(dui)(dui)接(jie)(jie)(jie)(jie)(jie)鋁(lv)(lv)(lv)層(ceng)耐(nai)壓性能差，是搭(da)接(jie)(jie)(jie)(jie)(jie)還是和對(dui)(dui)接(jie)(jie)(jie)(jie)(jie)可從鋁(lv)(lv)(lv)塑復(fu)合管的截(jie)面處觀察。

5、估算采暖需求

通(tong)常住宅內(nei)應安裝多(duo)少瓦(wa)的暖氣片的計算(suan)比較復雜(za)，但可(ke)按45～70瓦(wa)/平方(fang)米估(gu)算(suan)。

在估(gu)算時(shi)，還應考慮(lv)樓房(fang)或平房(fang)、頂層或底(di)層、端(duan)頭(tou)或中間、北方(fang)或南方(fang)、城里或城外(wai)、墻體(ti)保溫性等因素。在計(ji)算出(chu)散熱量的(de)大小(xiao)后，再適當多加10%～20%的(de)富余量。除(chu)此(ci)之(zhi)外(wai)，消(xiao)費(fei)者須(xu)提(ti)供(gong)所用(yong)供(gong)暖系統接口的(de)口徑、進(jin)出(chu)水(shui)方(fang)式等基(ji)本數據。

6、認準知名品牌

消費者(zhe)選購暖氣(qi)片一定要認準(zhun)品牌(pai)，選擇正(zheng)規品牌(pai)的暖氣(qi)片。據統(tong)計，截至目(mu)前，家(jia)用暖氣(qi)片生產(chan)企業已有2000多家(jia)，總(zong)產(chan)量發展到約10億片，總(zong)產(chan)值達到近200億元。然(ran)而，這些企業中(zhong)具(ju)備生產(chan)規模，實力較強的知名品牌(pai)生產(chan)企業不過10多余家(jia)，具(ju)有中(zhong)等規模的生產(chan)企業也(ye)只有幾十家(jia)。

良莠(you)不齊(qi)的(de)市(shi)場直接造(zao)成(cheng)了行(xing)業和市(shi)場的(de)無(wu)序：產品(pin)、零配件不合格，安(an)裝不規范，材質與系(xi)統不配套等問題(ti)不斷出現。所(suo)以，消費(fei)者(zhe)好(hao)到正規市(shi)場選擇知名品(pin)牌的(de)暖氣片，除有質量保(bao)證外，還有完(wan)善的(de)安(an)裝和售后保(bao)障體系(xi)。
