Are you crazy, a whole house electric heater in Texas is on a 50 amp 240v breaker and the whole house AC unit is on a 30 amp with the blower on a 15 amp 120v. 60% of Texans have electric heat as was demonstrated in February when they crashed the grid in record cold temps. 50 amps is 12 kWh, 30 is 7.2, resistance heaters are 10kw and they run on a 30% over a 24 hour duty cycle typically.
I have dual HVAC both on 30 amps when they are roaring it’s 60amps draw with both blowers running on high. My home circuit is a 300 amp grid tie the guest house is 200 for a 500 amp total to the pole.
Apparently electric wiring is also not one of you strong points either. Circuit breakers are designed to protect the wiring. They do not indicate what the typical load is. You also did not read my post very well. You are talking about whole house heatpumps with resistive heating units. So do you think that they use more electricity while heating or while cooling?
Here is a link to a chart with the amount of electricity that a typical window air conditioner uses.
