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.

Thanks

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