Is this allowed on Shabbat for showers

Enjoy Hot Water on Shabbat & Yom Tov!

I’m having a hard time fully understanding his description of how it works.

But it sounds like the main feature here is that the water stays below Yad Soledet. The Rabbi was a big fan of this and always recommended lowering the hot water heater to be below 125° and then you can use the hot water no problem on Shabbat.

However you still can’t take a shower. Separate Gezera M’drabanan. Regardless of how the water was heated up.

The exception is if one is “Mitzta’er” - very uncomfortable. Then one is permitted to shower.

I watched the videos. Got how it works. No problem.

Again, doesn’t help for showers.

Question does the gezera of מרחצאות apply to water that is not as hot as one normally takes during the week to shower ,

for example if one normally showers with water at 100 degrees and now would set this heater before shabbos to 98 degrees

עיין אגרות משה אורח חיים חלק ד סימן יד דיני רחיצה?

Lowering it a little bit doesn’t change anything.

Can you double check that מראה מקום?
