This depends on the design of the tank for under pressure. The vaccum breaker is then sized to slightly under the design under pressure. So in this case, the vaccum breaker will open before the design under pressure is reached to protect the tank.

What size breaker is needed for a 220 v hot water heater?
The wattage of the water tank is needed to size the breaker and the wire to feed the tank.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.

What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.
What is the difference between Air circuit breaker and Vacuum circuiut breaker?
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
What size amp circuit breaker should be used for a hot water tank?
Assuming you are referring to a 240 volt residential hot water heater you will need to install 10/2 NM cable (Romex) with ground from the service panel to the water heater wired to a 30 amp circuit breaker in the service panel. If you cannot see the water heater from the service panel you will need to install a service disconnect at the water heater.

The vacuum breaker prevents contaminated water from the drain being sucked back into the appliance if it has a fault.

Yes.
What is Vacuume Circuit Breaker?
A vacuum circuit breaker is a high-voltage circuit breaker whose contacts separate within a vacuum dielectric. The vacuum contributes to extinguishing the resulting arc because ionisation cannot take place while the arc is stretched between the separating contacts.
