家庭采暖哪種更劃算？

2020-08-26 63054

目前，市場上的采暖方式五花八門，各式各樣，下面就列舉幾種常見的家庭采暖方式，供大家參考!

　　小太陽取暖器

　　南方很多家庭都備了小太陽取暖器，特別是體積小，價格便宜，可隨意移動，升溫速度快。缺點是受熱面積太小，耗能也非常高，算是比較簡陋的采暖方式。

　　空調采暖

　　空調既可以采暖也能制冷，一機兩用，非常方便。不過，空調的強項是制冷，在冬季氣溫達到零下5℃時，空調是否能正常工作都成問題。而且空調是從上而下的熱風傳遞采暖方式，熱量集中在人體的中上部，最怕冷的腳部依然感覺冰涼，舒適效果差強人意。

　　地暖

　　地暖是通過在地板下鋪設管道的方式，來達到取暖的目的。與空調采暖相反的是，地暖的熱量是從下往上傳遞，給人一種腳暖頭涼的感覺，這恰恰符合中醫(yī)提倡的養(yǎng)生理論，特別適合有老人和小孩的家庭。不過，地暖需要在地板下鋪設管道，如果是裝修好的家庭有很大的不便。

　　暖氣片

　　相比于地暖，暖氣片采暖雖然舒適度要遜色一些，但是遠強于空調采暖，而且安裝沒有太多的限制，裝修好的家庭也可以安裝。

　　當然，地暖和暖氣片只是采暖未端，真正起決定性作用的還是熱源設備。目前市場上比較節(jié)能的有燃氣壁掛爐和空氣源熱泵，在天然氣價格低于2元每立方的地區(qū)可以使用燃氣壁掛爐，而高于2元每立方的使用空氣能采暖采暖更劃算。
