Can we boil water inside the artificial satellite by convection?

The convection currents are only possible in the presence of gravity. When we heat water, the water at the bottom becomes hot and light as compared the water at the surface of the top. The presence of gravity makes heavy cold water molecules on the top to go down. Hence, the lighter water molecules at the bottom will move up. 
In artificial satellite due to weightlessness the convection current is not possible. Hence, we cannot make water boil on artificial satellite by the process of convection.
