Quick answer
For Puget Sound homes, whole-home electrification is where the money, the code, and the grid are all heading: WA HEAR stacks up to $14,000 in point-of-sale rebates for income-eligible households, our hydro-heavy grid is already clean, and heat-pump economics beat gas for most loads. Staying dual-fuel remains reasonable for mid-life gas equipment — but plan the sequence now, because the math punishes homes that leave one appliance stranded on a full gas bill.
- This is a strategy question, not an appliance question: the order you electrify in determines whether you pay for panel work once or three times.
- The sequence that works: panel/service first, then heat pump, then heat pump water heater, then EV charging, then induction — each step rides the capacity the first step built.
- The rebate stack is real: WA HEAR (income-eligible) combines up to $14,000 across heat pump, HPWH, panel, and wiring; WA's IRA HOMES whole-home program reaches up to $20,000; PSE adds $500–$1,500 for heat pumps.
- Watch the gas bill's fixed charges: as loads leave, the monthly meter charge is spread across less and less usage — the last gas appliance is the most expensive therm you'll ever burn.
- Seattle and WA code restrict gas in new construction; existing homes are unaffected, but the policy direction is unambiguous and one-way.
What does each option cost installed in the Seattle area?
Whole-home electrification is a multi-year project measured in stages, not a single invoice — and the rebate stack changes the net dramatically for income-eligible households. These representative Seattle-area ranges frame the paths; a load calculation and rebate check turn them into a real plan.
| Option | Typical installed range | What that covers |
|---|---|---|
| Full electrification (panel + heat pump + HPWH + EV circuit + induction) | $30,000–$60,000+ before rebates | Spread over years by sequencing. WA HEAR can return up to $14,000 (income-eligible, point-of-sale) and WA IRA HOMES up to $20,000 for qualifying whole-home retrofits. |
| Staying dual-fuel (replace gas equipment in kind) | Lower per-replacement cost | No wiring or panel work, but no rebates, exposure to gas prices near $1.60/therm and rising, and fixed meter charges that never leave the bill. |
| Electrical backbone alone (panel/service + SPAN) | $5,000–$15,000 | The enabling first step either way — HEAR adds up to $4,000 toward the panel and $2,500 toward wiring when it enables electrification (income-eligible). |
What changes the price
- Panel and service capacity: the gating decision for everything downstream — a load calculation tells you whether you need 200A, or whether SPAN load management lets the existing service carry the plan.
- Rebate eligibility and stacking: HEAR (≤150% area median income) is point-of-sale with a $14,000 combined cap; IRA HOMES scales with measured whole-home savings; PSE rebates stack for its customers. The federal 25C credit expired 12/31/2025.
- Sequencing and timing: replacing equipment at end-of-life spreads cost naturally; emergency replacements force rushed decisions at full price.
- Gas infrastructure: capping lines, rerouting for a remaining appliance, or decommissioning the meter is licensed gas-line work that belongs in the plan.
- Permits across three trades: electrical, mechanical, and plumbing/gas permits each apply at different stages — one integrated team keeps the sequence coordinated instead of three contractors pointing at each other.

How do they work differently?
How a dual-fuel home operates
A typical Puget Sound dual-fuel home splits its energy across two delivery systems: gas feeds the furnace, water heater, and maybe the range and dryer, while electricity runs everything else. You pay two sets of fixed monthly charges for the privilege. The gas side burns fuel at 80–98% efficiency where you use it; the arrangement is familiar and the equipment is cheap to replace in kind. Its quiet weakness is arithmetic: the gas meter charge is constant, so every appliance that leaves gas makes the remaining therms more expensive — a treadmill that speeds up as you electrify piecemeal without a plan.
How an all-electric home operates
Everything runs on one meter fed by Washington's hydro-heavy grid at about $0.12/kWh. Heat-pump-class equipment does the heavy lifting — space heating at 2–4 units of heat per unit of electricity, water heating for roughly $150/yr for a typical family — and induction handles the stove. The panel becomes the home's energy hub; with SPAN it's a managed one, pacing the EV charger and prioritizing circuits during outages, and with a battery it's a resilient one. One bill, one fixed charge, no combustion in the living space, and every future efficiency gain (better equipment, solar, smarter rates) plugs into the same system.
Pros and cons, honestly
Whole-home electrification
Pros
- Captures the largest incentive stack Washington has offered: up to $14,000 HEAR (income-eligible, point-of-sale), up to $20,000 IRA HOMES whole-home, plus PSE's $500–$1,500 heat pump rebate
- Heat-pump economics beat gas for space and water heating at Puget Sound rates
- Eliminates the second fixed charge — the gas meter fee leaves with the last appliance
- Runs on an already-clean hydro grid, so the carbon win is immediate, not someday
- Aligns with where Seattle and WA code are heading instead of fighting it
Cons
- Serious total investment — $30,000–$60,000+ before rebates if done all at once
- All-electric means outage-exposed: a battery, generator, or hybrid backup becomes part of the honest plan
- Panel or service constraints can gate the timeline (though SPAN load management often relieves them)
- Poorly sequenced, it costs more — electrical work done piecemeal is electrical work paid for twice
Staying dual-fuel (natural gas)
Pros
- Lowest near-term cost — replacing gas equipment in kind avoids wiring and panel work
- Gas water heating and cooking remain cheap to operate today versus resistance electric
- Older gas appliances keep working through windstorm outages
- No sequencing project to manage; each replacement is a simple like-for-like decision
Cons
- Two sets of fixed monthly charges indefinitely — and the gas fixed charge grows relative to shrinking usage as anything electrifies
- Zero rebate support: every 2026 incentive dollar is electric-only, and waiting risks program funds being exhausted
- Exposed to gas at roughly $1.60/therm and rising, plus whatever future carbon policy adds
- Combustion stays in the home, with the venting, CO, and air-quality considerations that come with it
Which one should you choose?
Choose whole-home electrification when
Major gas equipment is approaching end-of-life — that's the moment the switch costs least, because you were writing a replacement check anyway. It's the clear strategy if you qualify for HEAR (the $14,000 stack transforms the math), if you're planning an EV (the panel work does double duty), or if you're renovating and walls are already open. Think of the Eastside remodel case: new 200A service with SPAN, heat pump replacing the dying furnace, HPWH the following spring, EV charger when the car arrived, induction with the kitchen — each step cheap because the first step planned for all of them. That's the pattern: backbone first, appliances as they fail, rebates at every stage.
Choose to stay dual-fuel when
Your gas furnace and water heater are mid-life and running well — scrapping working equipment rarely pencils out, rebates or not. It's also the honest near-term answer if the upfront budget isn't there even after incentives, if you rent out the property and can't capture the operating savings, or if you're in an outage-prone pocket and not ready to invest in backup power. Staying dual-fuel done well still means preparing: run a load calculation, rough in wiring during any remodel, and know your sequence — so when the furnace dies on a February morning, you execute a plan instead of panic-buying whatever's on the truck.
Also consider: partial electrification, done in the right order
Most Puget Sound homes actually land here for a few years: heat pump first (biggest load, biggest rebate, and it adds the air conditioning gas never gave you), water heater at its next failure, kitchen and dryer last. The one discipline that separates a smart partial from an expensive one: size the electrical backbone for the finish line at step one. Wiring for the whole plan once costs a fraction of revisiting the panel three times.

Common questions
What order should I electrify my home in?
Backbone first: confirm panel and service capacity (upgrade to 200A or add SPAN load management if needed), because everything else depends on it. Then heat pump — biggest load, biggest rebate, adds cooling. Then heat pump water heater, then EV charging, then induction cooking. Swap each gas appliance at end-of-life rather than scrapping working equipment, and the project spreads naturally over a few years.
How much can rebates really cover in Washington in 2026?
For income-eligible households (≤150% area median income), WA HEAR stacks point-of-sale rebates up to a $14,000 combined cap: heat pump up to $8,000, HPWH up to $1,750, panel up to $4,000, wiring up to $2,500 — and HEAR also covers qualifying electric cooking appliances. Washington's IRA HOMES program adds up to $20,000 for qualifying whole-home retrofits, and PSE customers can add $500–$1,500 for heat pumps. The federal 25C credit expired December 31, 2025 — don't count it.
What happens to my gas bill as I electrify appliance by appliance?
The usage charges fall but the fixed monthly meter charge doesn't — so the cost per remaining therm climbs as loads leave. A home keeping only a gas fireplace or range pays the full fixed charge for a trickle of usage. That's why the endgame matters: either keep enough on gas to justify the meter, or plan to retire it entirely and bank the fixed charge as savings.
If I go all-electric, what happens during a windstorm outage?
This is the honest tradeoff of electrification, and it has real answers: a home battery (Tesla Powerwall, FranklinWH) covers the short outages most urban Puget Sound homes see, a Generac standby generator covers multi-day rural events, and SPAN circuit prioritization stretches battery runtime by shedding non-essentials. Backup power belongs in the electrification plan from day one, not as an afterthought.
Why does it matter that one company handles the whole transition?
Electrification crosses three licensed trades — electrical (panel, wiring, EV, SPAN), HVAC (heat pump), and plumbing/gas (HPWH, gas-line capping). Split across three contractors, the sequencing errors show up as change orders and repeat panel visits. Eco holds all three licenses (WA Lic. ECOELEP765P5), so the load calculation, rebate paperwork, and multi-year sequence live in one coordinated plan.
