New tenant complained about how hot the water was, so I opened up the
unit and found both thermostats turned ALL the way up. The manual says
this is around 190F (!). I turned them all the way down to the factory
setting which is supposed to be 120F, or below the 125F scald standard.
There isn't a dishwasher. Is there any legitimate reason it would have
been turned up so high, e.g. something to do with the HVAC (each unit
has its own)?
Sounds like you either have 2 water heaters, or an electric water heater with 2
The only reason I can think why someone would crank them to the max, would be
because they once ran out, and figured that would be less likely to happen
again if the water was hotter, and therefore you'd use less of it during a
shower, washing dishes, etc.
If it is a tankless hot water heating system, the two stats are for off and
on settings. Kicks off at the high set point, comes back on at the low set
point. Baseboard heaters are usually more efficient at higher temperatures.
It can also be as you said, less volume is needed to mix in with the cold
water if there is not enough supply.
In any case, 190 is much to high.
Sure if you are paying the bill, Who pays the bills, ? You ? or the
tennant? You should start at the lowest temp where No cold water is
added to shower, thats YOUR set point, if You pay the bill. If they
PAY , its not your bill
I've seen this a couple times, on rental property, and once in a frame home.
Seems that some half brained idiots think that if you want the water a
little hotter, you turn it on max. I can't explain the mindset.
It is the same mindset as the negro welfare mommy who kept turning the
fridge settings up to 9 and E, and then calling the landlord to complain
that the fridge was warm. I tried to explain it to her a couple times, and
then started billing her fifty bucks a trip.
Just write it off as idiots who oughta not be allowed to own screw drivers
