For a kitchen sink or quick washing tasks, a 3-litre instant water heater can be sufficient. If you want slightly more capacity for bathroom use, a 5-litre model may be more suitable.
You should also look at the heating element, tank material, pressure rating and safety mechanisms. These features can influence how the appliance performs and how well it fits your home's water supply.
A storage geyser, on the other hand, keeps a larger quantity of heated water ready for use. It may be more suitable when multiple people need hot water consecutively.
For smaller, quick-use requirements, an instant geyser can be a convenient choice. For higher-volume household use, a storage model may make more sense.
For smaller requirements, the 3-litre AO Smith EWS Plus and ACTIVA Volcano are worth considering. Ultimately, look beyond capacity and compare the heating element, tank construction, pressure rating, safety features and warranty before making your decision.

It may be more suitable when multiple people need hot water consecutively.
