how to use geyser in bathroom - #36762

I am really struggling with my geyser in the bathroom. Like, I feel like every time I turn it on, things just go wrong! Last week I tried to have a nice hot shower after a long day, but somehow, it turned into a freezing disaster! I mean, I thought I knew how to use the geyser, but maybe I just don’t know the right way or something. I usually flip the switch, wait a bit, then hop in, right? But then the water started off warm, then went icy cold outta nowhere! . I checked the settings, and they all seem fine, but honestly, I have no idea if I’m missin’ some trick in how to use geyser in bathroom properly. Also, I noticed that sometimes the water doesn’t seem to stay hot for long. Is that normal with geysers? I mean, especially when it’s winter and I just wanna have a nice long warm shower? Do you guys have any tips or recommendations on how to use geyser in bathroom to get the best results? I’m tired of playing this hot-cold game every time I shower! Any guidance would be super helpful! Thanks a bunch!
