i've got an older gas fired water heater in my house - came with the
house, I guess it's probably about 20 years old. It works fine, but I
do have one issue with it. If I am the *first*
person to take a
shower in the morning, I leave the valve on full hot, and I have a
somewhat acceptably warm shower, but not quite as hot as I'd like. If
someone else showers first, they experience this same effect, but by
the time they've left the bathroom and I go in to take *my*
am rewarded with steamy hotness. It's like the hot water heater will
maintain a certain temperature if it sits overnight, but once someone
starts drawing off hot water it heats the water up even hotter.
I tried simply increasing the temperature setting on the HWH, but that
caused the pop off valve to activate a couple of times.
Any ideas if there's an easy adjustment I can make, or what the
problem might be? I can't really afford to buy a new hot water
heater, although I know that it's old enough that I will have to if it
ever stops working for any reason.
