受教了。至少知道了我的HVAC system没出问题。
You are welcome
现在外面冰天雪地的,这个heat pump岂不是非常低效. 我是否应该干脆把楼下的gas
system温度调高来减少楼上的系统的工作?
Not sure what your gas price compare to electric price, different of the
country is different. But you could do that.
还有它有一个emergency heat,是不是用它
就变成电热丝发热从而停止那个Air-Source的compressor呢?
Yes, but COP of EM heat is always 1. With heat pump running, you might get
more than 1, even if is below freezing outside. But that depend on the
system you have.
