貯水式電熱水器通過加熱管將內膽里的水逐漸加熱，加熱時間的長短取決于內膽容量的大小以及加熱管的功率、水溫、環境溫度等因素。一般在冬天貯水式電熱水器加熱時間都會變長。 一、家用抽油煙機如何選擇 1、看風壓 家用油煙機選購的時候，首先要考慮的因素，就是油煙機的風壓。風壓是衡量油煙機使用性能的一個重要指標，一般風壓值越大，抽油煙機抗倒風能力就越強。所以在選購油煙機的時候，選擇風壓值越大的越好。 2、看噪聲 油煙機的噪聲也是選購油煙機的一個重要指標，主要是指抽油煙機在額定電壓、額定頻率下高轉速檔運轉測得的A聲功率級。選購油煙機的時候要注意，對于這個噪聲的指標值不應該大于74dB。 3、看細節 細節在很多方面能夠體現出油煙機的好壞，因而在購買油煙機的時候，要注意抽油煙機罩煙結構的內層，不能有接縫和溝槽，否則就會積滿油污和油滴。這種的油煙機日后使用會不方便清潔，應該避免選擇。 -----吸油煙機代理
