Presumably geothermal vents can heat up water which can send it rising?

Yes, but geothermal vents are highly localised and have a negligible contribution to the whole-ocean heat budget. Plumes associated with hydrothermal vents are important biologically and geochemically, but not for ocean physics as a whole.
