Will it fit
- Footprint
- Exterior Height: 87" x Width: 69" x Depth: 47" (Roof: 79" x 61" x 87")
- Placement
- Outdoor
- Plug-in or 240 V
- Runs on 120 V; no 240 V wiring needed.
- Circuit
- Dedicated 120V, 20 amp (ETL/CSA Certified), as the maker publishes it.The maker specifies a 20 amp circuit, which is the largest a 120 volt supply provides in a home. This heater draws 17.5 amps, so the 125 percent continuous load rule leaves no headroom: it needs a dedicated circuit with nothing else on it. NEC 422 gives the rating marked on a listed appliance authority over the calculation, so ask your electrician to confirm the marked rating before wiring.Check it on the calculator.
Key facts
- Running cost
- About $0.38 per one-hour session: a 2.1 kW heater at the US average residential rate of 18.31 cents per kWh (EIA, July 2026).
