Before you buy a heat pump, an EV charger or another big electric appliance, make a simple home upgrade plan: list everything you might add, have an electrician check how much electrical capacity your home has, then choose equipment and order the work so the panel and wiring are planned once. It is the cheapest way to avoid doing the same electrical work twice.

Why the order of upgrades matters
A heat pump, an EV charger, a heat pump water heater, an electric dryer and solar panels can all touch the same thing: your home’s electrical panel and service. Buying them one at a time without a plan can mean paying for electrical work twice, or finding out after the purchase that the panel is already full.
A short plan before you buy anything helps you decide what to do first and what to prepare for later.
Step 1: Write down what you might add
List every electric upgrade you might want in the next five to ten years, even the ones you are unsure about. For example: a heat pump for heating and cooling, an EV charger, a heat pump water heater, an induction range, a heat pump dryer or solar with a battery.
You do not need to buy them together. The list is there so the electrician can plan the panel and wiring once, instead of one appliance at a time.
Step 2: Find out how much electrical room you have
The DOE training module on electrical panel assessment for heat pumps teaches installers to “determine a home’s electrical panel size” and to “Understand your electrical load and service capacity needs when adding circuits for new appliances.” In plain words: someone needs to check how much power your home’s service can supply and how much is already being used.
For EV charging, the U.S. Department of Energy Alternative Fuels Data Center page on charging at home says: “Electricians can inform homeowners whether their home has adequate electrical capacity for vehicle charging. Some homes might have insufficient electric capacity for Level 2 equipment.”
Ask the electrician to look at your whole list from Step 1, not only the first appliance. Our guides on whether a 100-amp service can support an EV charger and a heat pump and on panel replacement vs service upgrade explain what that check can find.
Step 3: Pick the equipment that fits the plan
For EV charging, DOE notes that many owners “are able to meet their daily driving range requirements by charging overnight with Level 1 equipment, requiring no additional cost or installation, provided that a power outlet on a dedicated branch circuit is available near their parking location.” Level 2 (240 V) equipment is for drivers with “less regular schedules, longer commutes, or EVs with large batteries.” DOE also suggests checking the vehicle manufacturer’s guidance before buying charging equipment or electrical services.
Before choosing a heat pump, ask how it was sized. Our heat pump sizing checklist covers the questions to ask. When the panel is tight, our guide on EV charger load management explains when managing loads may avoid a service upgrade.
| Upgrade | What to ask before buying |
|---|---|
| EV charger | Level 1 or Level 2? Is there capacity for a dedicated circuit? Who handles the permit? |
| Heat pump | How was it sized? What circuit does it need? Does it fit the panel plan? |
| Heat pump water heater | Is there space, airflow and drainage? What circuit does it need? |
| Electric range or dryer | Is a new circuit needed? Can it share capacity with other loads? |
| Solar and battery | Does the panel need changes now to avoid redoing work later? |
Step 4: Plan permits, incentives and rates
DOE says charging installations “must comply with local and state codes and regulations” and that “Appropriate permits may be required from the local building and permitting authorities.” Ask who will pull the permits for each part of your plan.
DOE also notes that “State and utility incentives may be available to help offset the cost of charging equipment” and that some utilities offer time-of-use or other rate incentives. Check what applies before you buy, because some programs have conditions. Our guide to federal home-electrification incentives in 2026 covers what still applies.
Step 5: Get quotes for the plan, not just the product
Ask contractors to quote against your written plan so you can compare like for like. Our guide to comparing home repair estimates shows how to line quotes up without knowing the jargon, and our EV charger panel upgrade guide covers the most common electrical question.
Frequently asked questions
Do I need a panel upgrade for a heat pump or EV charger?
Not always. An electrician needs to check your service capacity and existing load. DOE notes some homes have insufficient capacity for Level 2 charging, and a qualified electrician can advise what is needed.
Can I charge an EV with a regular outlet?
DOE says many owners meet daily needs charging overnight with Level 1 equipment if a power outlet on a dedicated branch circuit is near where they park.
Do EV charger installations need a permit?
DOE says installations must comply with local and state codes and that permits may be required. Check with your local building department.
Why plan all upgrades at once?
Several electric upgrades share the same panel and service. Planning them together helps avoid paying for electrical work twice or running out of panel capacity.
