近日消委會聯同機電工程署實測了20款家用氣體熱水爐，包括11款煤氣爐和9款石油氣爐，結果有近6成半獲評4.5分，有1款煤氣爐樣本未能通過部分安全測試。在獲評4.5分煤氣熱水爐中，售價較低的型號的整體表現未必較差，而最貴和最便宜的售價相差近一倍價錢，近$5000。
是次消委會與機電署合作的測試中，包括了16個牌子共20款的住宅式氣體熱水爐，當中11款為煤氣爐，聲稱熱水流量（以溫升25℃計）介乎每分鐘10至16.8升；另外9款為石油氣爐，聲稱熱水流量（以溫升25℃計）介乎每分鐘10至13升。
測試發現，售價較低的型號的整體表現未必較差。測試中，消費者著重的「火力」就以熱負荷及熱水流量規格作主要參考項目。熱負荷（heat input）又稱為「熱流量」，即是輸入功率，可理解為隨燃氣輸入至熱水爐的能量。當中1款「皇冠牌」的煤氣爐售約4400元，與另1款售價貴逾1倍約$9100元、使用相同燃氣類別及聲稱熱水流量的型號比較，兩者的整體表現同樣出色，都獲評4.5分。
Click入圖睇13款消委會評分4.5分的氣體熱水爐：
機電工程署表示，泄壓閥壓力設定不符合爐身標示，是由於泄壓閥調校誤差所致，並不影響操作或產品安全。而「太平洋Pacific」的進口商表示，樣本在水路系統耐壓測試不符合爐身標示規格，是由於生產時泄壓閥調校值出現誤差，屬個別事件，並不涉及安全問題，亦不會影響產品正常操作。
