Enough CB Amps for Electric Heater?
I live in an appartment with 4 Electric Convection Heaters. 1500W, 1250W, 1000W & 500W all at 240 volts. The 500W heater in my bathroom needs to be replaced to a 1000W/2000W Forced Fan Heater. Can I install this type of heater with a Double 30amps Circuit Breaker (60amps in total) which handles all my 240 Volt, 4 heaters in my appartment? Will these breakers handle the load? What is the Maximum load I can use with these breakers?
Your answers will be appreciated.

Note - that 220 v 30 amp breaker is just that - 30 amps.
W=AxV. At nominal 220V
1500W=7.5A
1250W=6.25A
1000W=5A
The new heater looks like it would be 2000A at 220v =10A
So the 3 existing heaters with the replacement would be 28.75A, which is too large (I believe) for a 30A service - IIR, 25A is the most that should be run off that breaker

Hello RJW,
Thanks for your info. I have a question. See my photo attatchment. On my breaker it seems to be a double one. Is it 30A+30A=60A? or it's still rated at 30A for 220V?
still rated at 30A
