Yes. watts / volts = amps. 4800/240=20amps.
Current in amps = watts/ voltage in volts. If you have a 240 volt supply, it will draw 4800/240 = 20 amps, so no. This is a very powerful water heater, and would normally be wired into a dedicated circuit, presumably with a 30 amp breaker.
Use of a double pole breaker or a single pole breaker depends entirely on the application. If you don't know about the application, contact a qualified electrician in your area.
U.S. 240 VAC breakers are always double pole since they are protecting two legs of the circuit.
The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
Ovens typically run at 240 volts which will be a two pole breaker in your panel. Watts = volts x amps. 4800 / 240 = 20 amps. If by chance you are using 120 volts then double it to 40 amps. All wiring must conform to size of breaker used.

10/3 wire with 30 amp double pole breaker from panel box to water heater.

Single pole.
before the load
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
Ovens typically run at 240 volts which will be a two pole breaker in your panel. Watts = volts x amps. 4800 / 240 = 20 amps. If by chance you are using 120 volts then double it to 40 amps. All wiring must conform to size of breaker used.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
