In-Wall Heater

Not sure if this is the right forum or not, but here it goes.

In my laundry room I have a 2000 watt, 240 volt in-wall heater. This unit is a very old unit inwhich the heater coil/element is bad so I decided to replace this unit with a 4000 watt, 240 volt unit. Currently the 2000 watt heater is on a 20 amp circuit with 12/2 wiring. I have ran new 10/2 wiring to accomodate for the additional wattage, but I am unsure of the correct circuit breaker amperage I should use. I thought I read somewhere that I should use a 30 amp circuit breaker, but I'm thinking that a 20 amp would be correct as the 4000 watt unit is rated at 16.7 amps. Any and all replies are greatly appreciated. Please let me know if you have any questions.

I think if you check. A #10 wire on 220V and 4000 or 4500 watt will go for a 30 amp breaker ED
