how do you know what the temp is?
how are you measureing? or are you just thinking in your head the temp is fluxuating?
even a new heater will have different temps as it cycles thru water, tank emptyes, fills heats that sort of stuff
so are you just posting some thing your head is thinking or is there actually a fact that your measureing temps over a period of time .
how many degrees is it fluxuating?
