what i mean is do bacterias stay in the water even if you boil it or do they disappear?

Bacteria are killed by boiling water for a few minutes, but chemical toxins which may have contaminated the water remain, and would need removing by chemical means or filtration.
Warm water which has not previously been boiled may contain higher levels of bacteria, and hence toxins (depending on the bacteria and the substrate) than cold water that has arisen through a spring, or fallen as rain.

Water, whether hot or cold have bateriae called pathogens.
It normally is attacked by your body immune system and you don't get sick everytime you drink water. Body is a wonderful mechanism isn't it?
I would say you boil cold water at all times and consume the boiled water as soon as possible. Hot water, when left to cool - it does pick up bacteriae from the air.
But, personally - I love cold water fresh off the faucet. It is refreshing. I know it has all those thingamagics but - touch wood - haven't had any problems with that, yet.

When you boil the water, the bacteria dies. That's why when the city is having problems with the water system they will send out an advisory to boil all water before drinking or using in food.
If you put hot water on to boil it will boil faster then if you use cold water.

boiling water will kill the bacteria BUT once bacteria is active, like in the hot water heater, they produce toxins. the toxins are what make you ill and they are NOT destroyed by boiling. So start cold for boiling.

Boiling water cold or hot doesn't remove but kills the living organism and makes it harmless to us for consumption. However, if the pipes are old and there are traces of lead in the water, boiling does not remove this and it can be harmful to ingest. A lot of older buildings should have their pipes tested and the water for that matter. Young children or pregnant people who drink lead in the water can cause harm.

You should always use COLD water. Like Kate said- boiling does not get rid of chemical toxins and chemical toxins are much higher in hot tap water than in cold. Boiling the water only releases some of the water through steam, thereby concentrating the chemical toxins. If you simply start with cold water you will have less toxins to concentrate. I think that is worth waiting a few extra minutes for.

If you boil water it will kill the bacteria.

Start with freshly drawn cold water. It takes longer to boil but it retains more of its disolved oxygen and so makes a better drink.
