Control of Temperature of a water

I want to control the temperature of a water where the heating voltage is 220 volts which hates the water. Now how can I control 220 volts using Arduino board?

Even though you did not say, I assume that would be AC voltage? A SSR may be a good choice. (solid state relay).

Not cross-posting is a good choice too. It reduces the risk of banning.

Trying to help when someone has more than one post, is like spinning my wheels. I don't need to do that. Get rid of all but one thread, then we can start helping.

It’s OK, the other post has gone.
It won’t happen again.

Ok, great, thanks. When you are new to a forum, you don't know what is frowned on at first.

In the last few posts, I don't see any new questions. Was your questions answered already, or do you still have unanswered questions?
