Sauna Types

2024 Essentials: Understanding Sauna Electrical Requirements

Traditional Saunas

Traditional saunas, often called Finnish saunas, use a heater and stones to produce heat. The electrical requirements for these are specific. Voltage needed is typically 220-240V for home use. The Amperage ranges from 30 to 50 amps, depending on the heater’s size.

Infrared Saunas

Infrared saunas work differently. They use light to warm the body directly. Their electrical specifications are unique. Voltage is generally 110-120V for smaller units and 220-240V for larger ones. Amperage is between 15 and 20 amps for most home models.

Dedicated Circuitry

Dedicated Circuitry is key when installing a sauna. This means the sauna must have its own dedicated circuit and should not be shared with other appliances or outlets. It’s essential to prevent overloading and potential hazards..

GFCI Protection

GFCI Protection, or Ground Fault Circuit Interrupter, is a vital safety feature for sauna installation. This device detects any current leaks and instantly cuts off power, protecting users from electrical shocks.

Wire Sizing And Insulation

Wire Sizing and Insulation are critical. The correct size is crucial. Undersized wiring can overheat, creating potential hazards. Saunas typically require 30 amps with 10-gauge wire or 40-60 amps with 8-gauge. Wires should be insulated and moisture-resistant for the humid environment. They must be installed by a licensed electrician and be rated for high temperature and moisture. Conduit is used to protect wires from accidental damage and allow easy access for maintenance and repair.

Circuit Breakers

Circuit Breakers for saunas should be a dedicated circuit breaker, sized to match the sauna’s requirements. It should be labeled for easy identification and located near the unit for quick access.

Voltage Requirements

Voltage Requirements for saunas vary between 120 volts and 240 volts. Check the manufacturer’s specifications to determine the correct double-pole breaker needed.

Electrical Box and Disconnect Switch

An Electrical Box and Disconnect Switch that meets code requirements should be located conveniently to turn off power during repair or maintenance.

Lighting Requirements

Lighting Requirements for a sauna are specific. The lighting must meet code and be rated for high temperature and moisture. It should be located in a way that provides adequate light and allows easy access for maintenance and repair. Internal digital controls for lighting typically require a Voltage of 110-120V, which is standard. The Amperage is usually less than 5 amps. Lights should be connected to the main power source, but on a separate circuit from the primary heater circuit for safety.

How Many Amps Does a Sauna Use?

When you install a sauna at home, power consumption and current draw depend on the type, whether it’s inside, outside, small, portable, or infrared. For example, a 6-person traditional sauna might have a current measured in amps of electricity needed to operate.

The Voltage and amps provided varies by manufacturer and model. For common electrical heaters, it’s 15-20 amps. For wood-burning saunas, it’s 30-50 amps. Adding a sauna meets different requirements for indoor and outdoor settings. A licensed electrician should wire it to your circuit breaker in the electric panel, following the National Electrical Code to avoid tripping and safety concerns.

When purchasing a kit, confirm the capacity. Newer homes often have over 50 amp service, but older homes might only have 60 amp for the entire house. You may need to check and upgrade your electrical panel to raise the capacity.

For instance, in the Signature Series, Electrical Information for models like GSE-1 requires a 15-amp, 110 volt with a dedicated outlet. Models like GE-2, GSE-2, GSE-3, GSE-3C, GSE-4 in the Hybrid Series, and 2-Person Hybrid, 3-Person Corner Hybrid, 3-Person Hybrid, Badger, Colorado, Aspen Models for Model Years with no electrical modification need standard household outlets of NEMA 5-15R, 110 Volts, 15 Amp on a dedicated circuit outlet.

For Durango, Rio Grande Models, Model Years 2010 – 2019, and 2021 – Present, an upgrade in circuitry to 110 Volts, 20 Amp, NEMA 5-20R is required. The Model Year 2020 needs 220 Volts, NEMA 6-20R. For Big Bear, Vail, Montana Models, all Model Years need 220 Volts, 20 Amp on a dedicated circuit outlet, NEMA 6-20R.

Professional Installation

Professional installation is critical due to the technicalities and risks involved in setting up a sauna. It’s recommended to hire a licensed electrician with the right expertise to handle the sauna’s electrical components. This ensures everything is correctly connected and grounded, adhering to local codes and standards for safety and compliance.

Water Supply

The water supply in a sauna is required primarily for the purpose of creating steam. A licensed plumber should install this system, ensuring it’s equipped with a shutoff valve for safety and a backflow preventer to prevent contamination of the water supply.

Drainage

Drainage systems are needed to drain and remove excess water used in the sauna. Proper drainage allows for easy cleaning and maintenance. It should be equipped with a trap, a crucial component to prevent odors from backing up into the sauna space.

Ventilation

Effective ventilation in a sauna is necessary to remove excess moisture and provide fresh air, maintaining a comfortable and safe environment. The ventilation system should be installed in a manner that allows easy access for maintenance and repair and equipped with a fan and vent cap to prevent the entry of insects and animals into the sauna.

Regular Maintenance

Regular maintenance of a sauna involves routine checks to ensure continued safe operation. Key aspects include inspecting wiring, connections, and GFCI periodically to detect and address any malfunctions or wear. This regular upkeep is essential to maintain the functionality and safety of the sauna.

Are Saunas Expensive to Run?

Having a home sauna means using power to heat and enjoy it. Does it use extra electricity? Yes, but it incrementally affects your electricity bill. You might hardly notice the increase at the end of the month. For example, traditional 3-4 person saunas might cost around $4 to $6 monthly to operate if used 2-3 times a week. Although not “free to use,” they are substantially less expensive than paying for a health spa or club membership.

Conclusion

Understanding the electrical and plumbing requirements is crucial to ensure your sauna operates safely and efficiently. From wiring, circuit breakers, and voltage to the electrical box and disconnect switch, plus lighting, water supply, drainage, and ventilation, each aspect plays a vital role. Hiring licensed professionals for installation is key to adhere to code for a safe and effective setup.

For homeowners, understanding these aspects is essential for the safety and efficient operation of their sauna. Being aware of the demands of different types of saunas and ensuring things like dedicated circuitry and incorporating safety measures like GFCI protection allows homeowners to enjoy the relaxing benefits of a sauna with peace of mind.

FAQs
