Water heater question

Thanks in advance for your input.
I have just replaced my gas water heater.  But both my old and new one has an interesting problem: the water coming out of the water heater has different temperature on different days.
I have not changed the setting on the water heaters.  the water comes out of the same location in teh house.
It happens 10% of the time.  What I mean is: on 10% of the days, the water coming out would be much cooler than on other days.
I cannot think of any reason other than that the gas coming in is weaker?  Does not seem right.

我这两天也这样,估计里面有水垢需要放一下水。 -borisg- 给 borisg 发送悄悄话 borisg 的博客首页 (0 bytes) () 08/20/2014 postreply 19:03:20

将温度调高点,试试。水厚是放不掉的。再着,新的也不会有水厚的。 -pssci- 给 pssci 发送悄悄话 pssci 的博客首页 (0 bytes) () 08/20/2014 postreply 19:27:20
