Hot Tub, Sauna & Pool
Electrical Planning Done Right
A hot tub draws 40 to 50A. A sauna pulls 30 to 60A. Pool equipment adds another 50A or more. That's serious load on top of everything already running in your home, and it needs to be planned alongside your full electrification roadmap.

Every assessment runs on your utility's 15-minute interval data, analyzed under an engineered load calculation (OESC Rule 8-106(8)). Measured demand, not assumptions.
3 Ways Outdoor Loads Catch People Out
"Just Connect It to the Panel"
Hot tub and pool installers wire their equipment, but rarely check whether your panel or service can actually handle the additional load. A 50A hot tub on an already-loaded 200A service can push you past safe limits.
One Load at a Time Means Multiple Bills
Hot tub this year. Pool next year. Then the EV charger. Each one means separate permits, panel work, and electrician visits that could have been planned once.
Panel Condition Gets Ignored
Is your panel full? Are the breakers outdated? Is the service entrance rated for the total load? These need engineering answers before any new circuit gets added.
Not Small Appliances. Major Loads.
Hot tubs, saunas, and pools need dedicated circuits and careful panel planning, not a spare breaker slot.
♨️ Hot Tub
40 to 50A / 240V
Dedicated 50A or 60A breaker required
Standard 240V hot tubs need a dedicated GFCI-protected circuit. Heater elements alone draw 30 to 40A, plus pumps and controls.
- GFCI protection required (OESC)
- Disconnect switch within sight
- #6 AWG copper minimum, typical
- ESA permit and inspection required
🔥 Sauna
30 to 60A / 240V
6 to 12 kW depending on room size
Electric sauna heaters are high-draw resistive loads. A typical home sauna needs its own dedicated circuit and proper ventilation planning.
- Dedicated circuit, no sharing
- High-temperature rated wiring
- Properly rated disconnect
- ESA permit and inspection required
🏊 Pool Equipment
50 to 100A+ total
Multiple circuits: pump, heater, accessories
Pools aren't one circuit, they're a system: pump, heater, salt chlorinator, lighting, automation. A pool heat pump alone can pull 30 to 50A.
- Pool subpanel often required
- GFCI protection on all pool circuits
- Bonding and grounding per OESC Section 68
- ESA permit and inspection required
These Loads Stack Up With Everything Else
Your hot tub or pool doesn't exist in isolation. It shares a service with every other load you're planning.
Hot Tub
40 to 50A typical · the reason you're here
EV Charger
40 to 60A typical · probably next on the list
Heat Pump
30 to 60A typical · replace the furnace
Induction Range
40 to 50A typical · replace the gas stove
On paper that's 200A+ of new load alone. But with proper load calculations and diversity factors, most 200A services can carry it, if you plan it right from the start.
Typical Installer vs. Energable
TYPICAL INSTALLER
- "Is there room in the panel? Great, we'll add a breaker"
- No load calculation, just a check for empty slots
- No consideration for future loads you'll want
- You find out the panel is overloaded after installation
THE ENERGABLE APPROACH
- Analyze actual usage: Toronto Hydro data plus panel inspection
- Engineered load calculation with proper diversity factors
- Plan for everything: hot tub, EV, heat pump, sauna, pool
- Right-size the solution, often with no panel upgrade needed
Hot Tub and Pool on the Existing 200A
Homeowner wanted a hot tub and pool with heat pump. Their contractor said they needed 400A. The engineering told a different story.
🏠 The Situation
Contractor's assessment: "That's 173A of new loads. You need 400A service. Budget $35K to $50K."
📊 Our Engineering Analysis
200A service handles everything with a 49A safety margin. An outdoor subpanel distributes pool and hot tub loads cleanly.
