It’s best not to think about the non-water stuff that exists in the water pipes. I once had to open up our 200-litre water heater (which supplies the entire house) to replace the heater coil, and now have to live with the knowledge of what, and how much of it, was inside. “Ignorance is bliss” couldn’t be more accurate.
Read the manual. It might have a descale mode that pushes some descaling chemical through the pipes without heating it.
Source: I did it like a month ago. The water that came out was quite pulpy.
I cannot describe the expression I made at the word “pulpy” but “horrified” is probably as close as I’ll ever get.
