First, you need to calculate how many amps does this heater draw like this: Current (amps) = power (watts) / voltage (volt) The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities; Once you pick the gauge, you must use the appropriate breaker for the wire. In america the nec requires 125% protection of circuit so if you have an 18 amp heater then you would need to account for 23.4 amp. People choose breaker sizes for 220/240v breakers. There might be, in your code some extra you must factor in. Meaning you would need a 30 amp circuit breaker and 10 gauge wiring. The gauge—or size—of the wire used needs to match amperage rating (energy level) of the circuit. The ideal breaker size for an electric water heater should be a 20 amps breaker.
