The power consumption is unavoidable during the transferring procedure and this result in unusable thermal loss, the difference during the transfer can be named as efficiency.
但在转换的过程中，不可避免地会发生电能的消耗，并转变为无用的热能。这中间转换率的高低即是一般我们所通称的效率。
In that way, minimum heat loss is achieved. The construction of the heater unit guarantees it a long life span, and guarantees that the thermal transfer medium will be usable for a long time.
由此达到极低的热损耗，加热器的结构设计新颖，使得加热器的寿命延长，载热介质也能长时间使用。
