The water that comes out of my hot water heater is almost boiling. I live in an apartment and can't control it's temperature. I have a question: why can't I just use the hot water from my tap to make a tea instead of going to all the effort of boiling it in a kettle? Is there something wrong with the water in the water heater? Actually, I usually put it in a ceramic mug and nuke it. I guess many people in Europe have those under-the-counter instant water heaters.
