Whole-Home Electrification

Replace gas, oil, and gasoline. Pair with solar and battery. One Connecticut contractor planning the whole sequence - and stacking every incentive along the way.

The full stack

Service upgrade or Span

200A panel (or Span Smart Panel) becomes the new floor.

Solar + battery

Produce the clean power, store it for outages and peak rates.

Heat pump electrical

Replace oil or gas heat with a cold-climate heat pump.

EV charger

Level 2 charging tied to your solar.

Heat pump water heater

Dedicated circuit, smaller install, big efficiency gain.

Induction range wiring

240V circuit for the kitchen retrofit when you are ready.

Recommended sequence

  1. 1

    Service upgrade or Span Smart Panel

    Unblocks every other load. Quick to permit, single day on site.

  2. 2

    Solar + battery

    Produce the energy the rest of the stack will use.

  3. 3

    Heat pump (whole-home or hybrid)

    Single largest source of fossil-fuel use in most CT homes - replacing it is the biggest carbon and bill win.

  4. 4

    EV charger

    Quick install once panel capacity exists. Funds the eventual EV purchase.

  5. 5

    Heat pump water heater + induction range

    Natural replacement cycle - wire on the next remodel or appliance failure.

Whole-Home Electrification FAQs

Common questions from Connecticut homeowners planning the full electrification stack.

What is whole-home electrification?
It is the strategy of replacing fossil-fuel systems (oil or gas heat, gas water heater, gas range, gasoline car) with electric equivalents (heat pump, heat pump water heater, induction range, EV), and pairing that with on-site solar and battery storage so the electric loads come from clean, low-cost power. The result: lower combined energy spending, lower carbon, and resilience during outages.
In what order should I do everything?
The right sequence for most CT homes: (1) Service upgrade to 200A or Span smart panel - this unblocks everything else. (2) Solar + battery - produce the clean energy and add resilience. (3) Heat pump (whole-home or hybrid). (4) EV charger. (5) Induction range and heat pump water heater on natural replacement cycles. Doing it as one project saves coordination cost; doing it staged is fine if cash flow demands.
What does whole-home electrification cost in Connecticut?
A full residential electrification package - service upgrade, 9-10 kW solar, single battery, Level 2 EV charger, cold-climate heat pump (electrical side), heat pump water heater (electrical side) - typically runs $55,000 to $85,000 installed in CT before incentives. IRA HEAR rebates (if income-qualified), Energize Connecticut rebates, and the CT ESS incentive on the battery can reduce that, and we provide a written breakdown of exactly what applies.
How do you coordinate with HVAC contractors and other trades?
For the heat pump and heat pump water heater, the equipment side is installed by an HVAC contractor. We coordinate scheduling so our electrical rough-in is ready when the HVAC crew shows up. We work with several CT HVAC contractors and can recommend ones we trust if you do not already have one.
What rebates and incentives are available?
IRA HEAR program (heat pump + electrical rebates up to $14,000 for income-qualified). Eversource and United Illuminating rebates on heat pumps, EV chargers, and weatherization. CT Energy Storage Solutions on the battery. Smart-E financing. Specifics change quarterly - we walk through current eligibility on every estimate.
Can I phase the work over multiple years?
Yes. Many homeowners do the service upgrade and solar first, then add a battery a year later, then heat pump on a natural replacement cycle. We design the initial system so each future stage drops in cleanly with no rework.
