Can Your Panel Handle an EV Charger AND a Heat Pump? How to Tell
EV chargers and heat pumps are two of the biggest electrical loads a homeowner can add, and Minnesota is seeing more of both. The problem: a lot of panels that could handle one comfortably don’t have room for both.
Why this combination is different
A Level 2 EV charger typically draws 30-50 amps. A cold-climate heat pump, especially with backup electric resistance heat, can add another 30-60 amps depending on size. Stack both onto a panel that’s already running a full modern home, and a lot of older 100-amp services simply run out of headroom.
How to find out where you stand
- A licensed electrician can calculate your home’s actual electrical load — not just guess based on panel size — and tell you exactly how much capacity is left.
- If you know both projects are coming, it’s worth having that load calculation done before either purchase, not after the heat pump is already installed.
If you’re short on capacity
A panel upgrade to 200 amps (or a load management device that shares capacity between big loads) can solve this without a full service upgrade in some cases — it depends on your specific setup.
