My shower insight…until recently (when my building got solar) I had very high electric bills…to combat that, i stopped turning on the water heater…it took a while to adjust to…but now, my showers are faster (less water waste) and its better for you…and in my experience this is not a myth. I live in a constant warm climate and I am older…my skin is visibly healthier and my hair is softer…no expensive products…just cold water!

now, although my Luma bills are minimal(due to solar panels), I still do the cold showers, just for the “no-cost” skin care.

but more directly…people (who have it) love those water controls! I remember years ago “hooking up” with a guy in a fancy apartment. He invited me to use shower after, but implored me, “Whatever you do, don’t change my water temp setting!” I didn’t touch it, but it was my first time seeing anything like this…i remember thinking, “rich people don’t even have to adjust their water…they can even control and preset that!”
