Is my panel big enough?

Can my electrical panel handle a heat pump?

Direct answer · reviewed 2026-09-18

Many Greater Victoria homes on 100-amp service can take a single-head ductless heat pump on a new dedicated circuit, at about $500–$1,500our estimate. Central systems with electric backup, multi-zone systems and homes that already carry an electric range, dryer, water heater or EV charger are where the electrician's load calculation may call for a service upgrade to 200 amps, at $2,500–$6,000our estimate with BC Hydro involved. Only a licensed electrician can answer for your house, from a load calculation, not from the panel's label.

Conditions and exceptions

  • The answer is a calculation, not a rule of thumb: the code load calculation counts your existing loads, floor area and the heat pump's rated draw. Two houses with the same panel can get different answers.
  • A full panel is not the same as an undersized service. If the service can carry the load, a panel swap or sub-panel ($1,500–$3,000our estimate) solves it without BC Hydro.
  • The Energy Savings Program electrical upgrade add-on applies only when a fossil-fuel-to-heat-pump switch needs a utility service upgrade; a panel-only change is not rebated, and electrically heated homes are outside it.
  • Never open a panel cover to check. Photograph the closed panel and the outside meter base instead; that is enough for a first read.

Permits for a residential heat pump in BC
An electrical permit is required to connect a heat pump; a licensed electrical contractor normally applies on your behalf. In the City of Victoria the City issues electrical permits; everywhere else in Greater Victoria it is Technical Safety BC. A gas permit is required when a furnace or boiler is removed.
Homeowners may hold their own electrical permit for their principal residence, except strata lots, non-strata duplexes and homes with a business; like-for-like thermostat swaps need no permit. · Strata owners cannot hold homeowner electrical permits; written strata approval is needed before an outdoor unit goes on common property, and before a rebate pre-approval code.

How an electrician decides

The panel's main breaker tells you the service size; it does not tell you whether there is room. The electrician adds up the loads the code counts, the house's square footage, the range, the dryer, the water heater, any electric heat you are keeping, an EV charger, then adds the heat pump's rated draw and, for a central system, the backup strip. If the total fits under the service rating, a new two-pole breaker and circuit is the whole job. If it does not, the options are load management (a device that sheds the EV charger or backup strip when the house is near its limit), a larger service, or a smaller heat pump design.

The local pattern is fairly consistent. Post-2000 Westshore houses with an electric furnace usually have the capacity because the furnace was the big load already. 1960s to 1980s Saanich and Gordon Head homes with baseboards often have a 100-amp service that is fine for a couple of ductless heads and tight for a central system with a strip. Pre-1950 Victoria, Fernwood and James Bay houses can have 60-amp services or original wiring, and land in the $4,000–$8,000our estimate tier.

  1. Read the number on the main breaker handle without removing any cover; that is the service size in amps.
  2. List the big loads: electric range, dryer, water heater, baseboards or electric furnace, hot tub, EV charger, suite.
  3. Send those and the photos below through Get Help; the site gives a first read and, with your yes, an electrician does the load calculation.

What a panel or service upgrade costs in Greater Victoria

Four tiers cover almost every house. The figures are our estimate from Lower Mainland electrician tiers cross-checked against the electrical lines Victoria installers publish; no Island electrician publishes its own pricing, so treat them as BC-wide. The service upgrade tier is the one with a schedule risk as well as a cost: it needs a BC Hydro service change, which the electrician coordinates, and the site has no verified figure for how long BC Hydro takes on the Island, so ask the electrician for the current lead time before you book an install date around it.

The electrical service upgrade rebate, and who it is not for

The Energy Savings Program has an electrical service upgrade add-on worth Level 1 / any-income examples — ductless-single: $5,000; ductless-multi: $5,000; central-ducted: $5,000 at income Level 1, with lower caps at Levels 2 and 3. It has three conditions that rule out most people who search for it: the upgrade must be part of a natural gas, propane or oil to heat pump switch under the program; a utility line upgrade (the BC Hydro service change) must be required; and the registered contractor manages the upgrade. A panel-only change, a sub-panel, or an upgrade in an electrically heated home gets nothing from this add-on, and the CleanBC Home Renovation Rebate for electric homes has no electrical component at all. Income limits are 1 person: $51,100 / $63,900 / $102,100; 4 people: $94,900 / $118,600 / $189,800 (Level 1 / 2 / 3); the program decides eligibility.

A second local complaint: installers who quote the heat pump but not the electrical, or offer only a sub-panel. Ask early whether the quote includes a licensed electrician's load calculation and any service upgrade, or whether you must hire that separately; two quotes that differ by the service upgrade are not comparable.

Permits: City of Victoria versus everywhere else

An electrical permit is required to connect a heat pump; a licensed electrical contractor normally applies on your behalf. In the City of Victoria the City issues electrical permits; everywhere else in Greater Victoria it is Technical Safety BC. A gas permit is required when a furnace or boiler is removed. Homeowners may hold their own electrical permit for a principal residence that is not a strata lot, a non-strata duplex or a home with a business, but a service upgrade involves BC Hydro's connection and the heat pump's refrigerant side, so in practice a licensed electrical contractor holds the permit and the installer coordinates. Strata owners cannot hold homeowner permits and need written strata approval before anything goes on common property.

Whoever pulls it, the permit should appear on the quote with the fee and the holder named. Skipping it exposes you to an inspection problem at resale and, for rebates, to a paperwork failure.

What to photograph (with the cover on)

A first read needs four photos and no tools: the panel with its door open but the inner cover in place, close enough to read the main breaker number; the breaker directory on the door; the outside meter base and the incoming wire; and the nameplate of any electric furnace or water heater. Send them through Get Help. Do not remove the inner cover or touch breakers to test them; the first read tells you which tier to budget for, the electrician's calculation is the answer.

Questions homeowners ask

Can a 100-amp panel run a heat pump?
Often, for a single-head or small multi-head ductless system on a dedicated circuit. A central system with an electric backup strip, or a house already carrying an electric range, dryer, water heater and EV charger, is where a load calculation may push a 100-amp service over its limit. The electrician's calculation decides, not the panel size.
What breaker size does a heat pump need?
It depends on the unit's nameplate draw: small ductless units take a modest two-pole breaker, central units with a backup strip take considerably more. The site does not publish breaker sizes because they are a design decision from the equipment specification, not a homeowner choice.
Is a sub-panel enough, or do I need a service upgrade?
A sub-panel adds breaker spaces; it does not add capacity. If the load calculation fits under your service rating, a sub-panel or a same-size panel swap ($1,500–$3,000our estimate) is enough. If it does not fit, only a service upgrade or load management solves it.
Does the rebate cover a panel swap?
No. The Energy Savings Program add-on (Level 1 / any-income examples — ductless-single: $5,000; ductless-multi: $5,000; central-ducted: $5,000 at Level 1) pays only when a fossil-fuel-to-heat-pump switch needs a utility line upgrade. A panel replacement at the same amperage, or any electrical work in an electrically heated home, is not rebated.
