Can a 200 Amp Panel Handle a Heat Pump and an EV Charger?
Yes — in typical homes it fits with room to spare. With a heat pump and an EV charger on 200 A service, an example 2,800 ft² home reaches about 100 A (green) with gas appliances and 135 A (green) with an electric range, dryer and water heater (NEC® 220.83).
That leaves about 100 A free in the gas home and 64 A in the electric one. Your own numbers — home size and which appliances are electric — decide the result.

Questions
Does a heat pump replace my air conditioner in the calculation?
Yes, in our tool a new heat pump takes over from an existing central AC or heat pump, since one system does both jobs. Electric backup heat strips still count separately.
What size breaker does a heat pump need?
Whatever the outdoor unit’s nameplate says: the MCA sets the wire size and the MOCP is the largest breaker allowed. Tonnage alone isn’t enough to know.
How is an EV charger counted in the load calculation?
Under NEC® 2023 220.57 at 7,200 VA or the charger’s nameplate, whichever is higher. A 40 A charger counts as 9,600 VA.
Can a load management device avoid a panel upgrade?
Often. A listed energy management system pauses or slows the charger when the house is busy, and NEC® 2023 lets the calculation use its setpoint instead of the full load.
