Electrify the whole house — on a plan, not in a panic.
Room by room, in the order that saves money: envelope first, then the heat pump, the water heater, the kitchen, and the panel that powers it all. One note on scope: this is the house itself — vehicles and solar are different projects.
What 'fully electric' actually means
A heat pump heating and cooling the house. A heat pump water heater making the hot water. An induction range in the kitchen. A panel sized for all of it — wrapped in an envelope that's been sealed and insulated so every one of those machines gets to be smaller and cheaper. No gas meter, no oil tank, no propane deliveries.
The order is the strategy. Do the envelope first and the heat pump shrinks. Check the panel early and nothing stalls later. Time each swap to the equipment's age and your rebate windows, and a five-figure project becomes a sequence of manageable phases — the same logic as the full retrofit sequence and the weatherize-first rule.
The plan, one room at a time
Walk the house in this order and you've walked the project plan.
Basement / mechanical room
The heart of the project. The heat pump water heater goes here (it wants a bit of space and a condensate path), the electrical panel decision gets made here, and the rim joists get sealed and insulated here before any of it. Check panel capacity at planning time — not install week.
Attic
Nothing electric goes here — which is the point. Air seal the attic plane and insulate to a climate-appropriate target first, because every later decision (heat pump size, panel load, operating cost) improves when the attic stops leaking heat.
Living spaces
Where the heat pump serves. Ducted systems reuse existing ductwork where it's sound; homes without ducts get mini-split heads or a compact ducted unit. Placement, zoning, and thermostat behavior (set-and-hold beats deep setbacks) get decided room by room.
Kitchen
Induction needs a 240V circuit at the range location — many gas kitchens don't have one, and running it is a modest electrician job unless the panel is full. The range itself is the easiest swap in the whole plan and a good early win.
Utility / laundry
Optional but cheap to include while an electrician is already on site: a heat pump dryer runs on less power and needs no vent. Bundle the wiring with the kitchen or panel work.
Answer the panel question early
Every measure in this plan draws power, so panel capacity is a planning-stage question — a panel surprise discovered during a heat pump install stalls the job. The good news: 100-amp service goes further than its reputation. Load calculations often show headroom, 120V heat pump water heaters exist, and load-management devices can juggle big loads on small service. Find out where you stand before the first quote, and the heat pump conversation gets simpler — it's on the installer question list too.
A three-year template
Envelope + assessment
Energy assessment, air sealing, attic insulation, panel load check. Cheapest phase, most subsidized, shrinks everything after.
The heat pump
Sized from a load calculation on the improved house. Panel or circuit work rides along if needed.
The remainder
HPWH, induction, dryer — or earlier if the old equipment dies first. With the plan in hand, an emergency becomes a scheduled swap.
Equipment age sets the real schedule: a 12-year-old water heater belongs in year one, whatever the template says. "When the water heater dies" is a plan trigger, not a surprise.
Stack programs phase by phase
Each phase has its own rebate stack: state and utility programs for envelope work, equipment rebates for the heat pump and water heater, and — in states that have launched the federal HEAR program — income-eligible rebates up to $8,000 for a heat pump, $1,750 for a HPWH, $4,000 for a panel, and $840 for an electric range. The caveat matters: HEAR is live in some states, restricted or unlaunched in others, so treat those numbers as a ceiling to check, not a promise. The Rebate Matcher builds your actual stack; your state page has the program details; the heat pump and insulation hubs cover each measure in depth.
Electrification planning questions
How much does it cost to electrify a whole house?
It's the sum of parts, and the parts vary hugely by house and state: envelope work, a heat pump, a heat pump water heater, possibly a panel upgrade, an induction range and circuits. National cost references put a whole-home ducted heat pump alone at roughly $14,000–$25,000 before incentives. The honest total comes from pricing your measures and subtracting your rebate stack — which is exactly what a plan is for.
Do I have to do it all at once?
No — and you usually shouldn't. Phasing envelope first, equipment as it ages out, spreads cost and lets each phase shrink the next. What matters is having the plan so an emergency replacement (a dead water heater, a failed furnace) lands as a planned upgrade instead of a panic like-for-like swap.
Do I need a 200-amp panel to electrify?
Often not. A load calculation tells you; load-management devices, 120V heat pump water heaters, and smart panels stretch 100-amp service further than most people expect. Check capacity at the planning stage so the panel decision is made deliberately, not discovered during a heat pump install.
What should I electrify first?
Seal and insulate first — it's not electric, but it shrinks everything electric that follows. After that: whatever is oldest and closest to failure, because replacing proactively is cheaper than replacing in an emergency. For many homes that's the water heater; for others it's a 20-year-old furnace.
