為什么太陽能熱水器頻繁使用好?

  太陽能熱水器投入使用后,要經常使用,建議每天最好使用4至5次,間隔時間在4小時以內,這是因為: 
① 長時間地用水,對樓層較低的用戶來說,所用到的水實際上是管道中的低溫水(太陽能熱水器里面的水停留在管道中降溫后形成);尤其在北方冬季,外界氣溫低,有時達到-25℃以下,上下水管路內的水涼地很快,若是六層樓,一樓用戶每次需放掉一臉盆冷水,特別浪費,如果頻繁使用就好一些; 
②能有效防凍,讓上下水管路始終有熱源,加上保溫層,可有效防凍。在北方冬季,不少人還采用室內稍微打開熱水器閥門,往下滴水的辦法來防凍。
上一條:太陽能熱水器好幾天未用的熱水還能洗澡嗎? 下一條:冬季要把太陽能水放掉嗎?
