Welcome to /c/Tumblr

All the chaos of Tumblr, without actually going to Tumblr.

Rule 1: Be Civil, Not CursedThis isn’t your personal call-out post.

  • No harassment, dogpiling, or brigading
  • No bigotry (transphobia, racism, sexism, etc.)
  • Keep it fun and weird, not mean-spirited

Rule 2: No Forbidden PostsSome things belong in the drafts forever. That means:

  • No spam or scams
  • No porn or sexually explicit content
  • No illegal content (don’t make this a federal case)
  • NSFW screenshots must be properly tagged

If you see a post that breaks the rules, report it so the mods can handle it. Otherwise just reblog and relax.

The water heater in my house can be set all the way to 85c and it's right behind my kitchen tap, so it gets to that temperature within seconds. I've been wondering for a while if I could use it to just make tea instantly instead of putting the kettle on first, especially since I've read multiple times that 100c water is actually bad cause it can burn the tea leaves.

So far I haven't been able to try it because of some circumstances, but I might in the future.

In the US there is sometimes sludge at the bottom of the water heater that collects. You shouldn't drink hot tap water in the US.

Pretty sure your not supposed to drink the tap water at all in a lot of places. I know my city sends a letter multiple times every year saying not to drink the tap water. Cookings fine thiugh :/

Apparently, don't cook with it either:

Hot water dissolves lead more quickly than cold water and is therefore more likely to contain greater amounts of lead. Never use water from the hot water tap for drinking, cooking, or making baby formula.

It's not just the lead, it's heavy metals in general.

I just looked it up for my country and you're right. They don't recommend regularly drinking the hot water. There goes my experiment lol
