--- tags: Rentea, CoRent --- # 2021-07-21 水電現勘 Round I - 時間:19:30 - 地點:瓦窯溝公寓現址 - 參與者: - ddio - hkazami - peace ## 注意事項 1. 電線要用太平洋,無熔絲斷路器用士林電機 2. 詢問接地的作法 3. 確認總電的安培數限制 ## 想問的問題 1. 浴室 1. 浴室門口的牆面請水電檢查,確認以前有沒有管線或漏水問題(發現有神奇的牆面加厚) 2. 浴缸的位置是否有另一個排水孔? 3. 廁所牆面的水漬從何而來? 4. 排水孔該如何防止臭味? 2. 電 1. 廚房電器+冷氣的安培數大概如何計算瓶頸 2. 敲牆面管槽的話,會幫忙補水泥嗎? 3. 陽台想多接一個水龍頭 & 排水,做水槽 ## 用電試算 出自 - 小院的這篇: https://www.courcasa.com/p/gXq8 - 新竹縣政府: https://www.energy-hsinchu-county.org.tw/upload_img/images/news/%E5%B8%B8%E7%94%A8%E9%9B%BB%E5%99%A8%E8%80%97%E9%9B%BB%E4%BC%B0%E8%A8%88%E8%A1%A8.pdf 1. 15A/ea - 變頻冷氣(啟動時)、烤箱、麵包機 1. 8A/ea - 電鍋、快煮壺、豆漿機、吹風機 3. 4A/ea - 果汁機、電子鍋、洗衣機、吸塵器 4. 2A/ea - 充電中的筆電 5. 1.5A/ea - 冰箱、除濕機 7. 0.5/ea - 50W AC 電扇 9. 0.2/ea - 省電燈管、燈泡、24" 螢幕、17W DC 扇、各種嵌入式系統 總計: - 背景需求 - 電扇x2、各種嵌入式系統x3、冰箱、除濕: 4.3A - 起居需求 - 電燈x4、螢幕x2、筆電x2、15A 電器x1: 20.2A (工作時順便烤蔬菜或麵包) - 煮飯需求 - 果汁機、電子鍋、電鍋、烤箱: 31A - 熱天需求 - 冷氣: 15A 夏天煮飯 70.5A / 非夏日煮飯 55.5A / 日常起居 24.5A / 夏日睡覺 19.3A / 冬日睡覺 4.3A 以安全用量 8 成計算,最多到 70.5 / 0.8 = 88A ,不開冷氣煮飯 69A ## 當日流水 以下是時隔一週後的紀錄 XD ---- #### 幹線 1. 原本只有拉 30A 進到屋裡,所以整戶滿載時只能到 30A 2. 如果要拉 60A ,因為銅線本人要 22mm^2 粗,原本從樓下電錶,進到屋內電箱的管子不夠粗,只能從室外拉,包含電箱更換、向台電申請的成本,粗估要 10-12 萬,而且還不含室內電線重拉。 3. 現在銅貴,如果只拉 50A ,銅線可以細一點,改成 14mm^2 ,料錢可以省一點 5. 施工流程: 1. 向台電申請增加到想要的電流量 2. 電錶拆封,活線作業,將電從外面拉到房子裡 3. 裝新的外接配電箱 4. 請台電來確認無誤後,重新鉛封 6. 水電表示,真的要做那麼大的工程嗎?覺得很不划算 ---- #### 室內配線 1. 廚房必須拆天花板,因為上面應該有八角接線盒,要拆了才能重配電線 2. 從原本的配電箱看起來,只有一條往上走的(通常是電燈、開關),其他都是往下走的,懷疑可能全室共用一條迴路,但要詳細確認,才會知道原本的電是怎麼拉的。 3. 材料: - 電線:太平洋 - 無絨絲斷路器:士林電機 - 開關與插座:國際牌 5. 可能的風險: 1. 原本的電線管路,可能塞住了,電線不一定可以用原管路重拉。如果發生這件事的話,就只能重配 pvc 管,建議延牆角拉。 ---- #### 浴室 1. 天花板一樣要拆掉,才可以重配電燈,因為沒有留維修孔。水電表示拆掉裝新的沒多少錢。 2. 浴室因為都是明管,如果想要好看,又想要做乾溼分離,建議把水管藏在天花板裡,因為管線會交叉,就無法平貼牆面 3. 靠淋浴水龍頭側的牆壁,雖然有因為浴缸拆除,而重貼過磁磚,但看起來水還是有滲入牆內,隔壁房間的牆壁,敲起來有膨共。 4. 靠走道測的牆壁,明顯滲水,但不確定是樓下,還是原本的水管。 5. 其實牆壁膨共不一定要修,雖然它終究會有問題,但或許也還能維持幾年。如果要敲掉重作防水,那又是個大工程。 6. 建議先估電,浴室等決定工法後,再來處理。 ---- #### 其他 1. 師傅建議,可以先確定地板碰共的範圍,用膠帶標起來,方便拆除時溝通 ---- #### 心得 看來又是一項爆預算的項目,原本是抓 7-10 萬。但還是可以等詳細估價單,還有多問幾家水電看看。 1. 如果基礎工程必定要做的話,或許可以思考: 1. 有什麼是現在一定要做,否則之後要調整,成本會很高的? 2. 有什麼東西,是可以不用現在馬上做,又能保持彈性的嗎?例如 220 可以先預留,但現在先不拉嗎? > 像是壁貼因為貼上後就超難復原,所以以雖然便宜,但一律不考慮。 > 西門有建議地板可以不用全鋪,也是種方案,只是要處理,讓接縫處看起來不會奇怪。 [name=ddio] 2. 雖然水電知道我們預算不多,但後來想想 1. 其實他並不知道我們每項的預算要多少,像電本來就估了 7-10 萬,並不是幾倍的差距。 2. 知道預算後,水電的另一個直覺反應是,不要幫房東花那麼多錢修房子,所以電箱建議裝外面、電不要拉到 75A 等等。 3. 之前隨口問另一個水電時,也表示既然是租的,那多的插座接明管就好,應該也是類似的邏輯 3. 以後估價時,就算對方覺得我們目標很歪,也應該要先表明預算,讓對方判斷該用什麼工法施工,比較合適。 ---- #### 待做 1. 追估價單 2. 找其他水電來看現場 3. 學、諮詢、確定浴室工法,再開水的估價單 ---- 參考資料 - 水電爸爸在 2021-09 拍了[估價單解說](https://www.youtube.com/watch?v=uN1rrakugcI),有給高價和低價的範例,和解釋一點原因 {%hackmd 1LO5rpavTiK4_cFrTouudg %}
