Understanding the Different Power Levels of Electric Sauna Heaters

When choosing an electric sauna heater, it’s important to understand the different power levels available and how they relate to the size of your sauna, desired temperature, and heating time.

Power Level and Sauna Size

The power level of an electric sauna heater is measured in kilowatts (kW).

As a general rule, you need approximately 1 kW of power for every 50 cubic feet of sauna space. So, for example, a 6 kW heater would be appropriate for a sauna that is approximately 300 cubic feet in size.

Sauna Size (Cubic Feet)Required Heater Power (kW)
101 – 1503 kW
151 – 2004 kW
201 – 2505 kW
251 – 3006 kW
301 – 3507 kW
351 – 4008 kW
401 – 4509 kW
451 – 50010 kW

Remember, this is a general rule of thumb and other factors may come into play when determining the appropriate power level for your specific sauna. For example, the amount of glass surfaces will affect the the power requirement.

Power Level Impacts the Heating Time

The power level of your sauna heater also affects how quickly it can heat up your sauna to your desired temperature.

A higher-powered heater can heat your sauna quicker but may consume more energy in the process. If you prefer a lower-temperature sauna, a lower-powered heater may be sufficient.

Understanding the Electrical Requirements of Electric Sauna Heaters

Before purchasing an electric sauna heater, it’s essential to understand the electrical requirements of the heater and ensure that your home’s electrical system can accommodate it.

Voltage and Amperage

Electric sauna heaters typically require either 120V or 240V power, and the amperage requirements can vary depending on the heater’s power level. 110V heaters are also available, although they are more rare.

Higher-powered heaters will require more amperage to operate. It’s important to note that if you choose a higher-powered heater, you may need to install a dedicated circuit to avoid overloading your home’s electrical system.

Do I need a 3-phase or single-phase power supply for an Electric Sauna Heater?

Most homes in the US have a single-phase power supply. If you are unsure about your home’s power supply, it is best to consult with a qualified electrician.

Electric sauna heaters with a power output of up to 9 kW can function on both single-phase and three-phase power supply systems. For electric sauna heaters with a power output of 10.5 kW, a three-phase power supply is required. Commercial sauna heaters with larger power outputs, such as the Narvi Ultra Big, may require a specialist dedicated power supply.

It’s important to ensure that the power supply system in your home is compatible with the electric sauna heater you choose. It’s recommended to consult with a qualified electrician to ensure that your sauna heater is safely and properly connected to your home’s power supply system.

Wiring Considerations

The wiring requirements for your electric sauna heater will depend on the voltage and amperage requirements. If you’re installing a new heater, you may need to upgrade the wiring in your sauna room to meet the heater’s electrical requirements. It’s essential to use the appropriate wiring size and type to avoid any safety hazards.

Consulting an Electrician

If you’re not familiar with electrical wiring or unsure if your home’s electrical system can accommodate an electric sauna heater, it’s recommended to consult with a licensed electrician. An electrician can help ensure that your wiring is up to code, install any necessary upgrades, and ensure that your sauna heater is safely connected to your home’s electrical system.

Overall, understanding the electrical requirements of your electric sauna heater is crucial to ensure that it operates safely and efficiently. By considering the voltage and amperage requirements, wiring considerations, and consulting an electrician if necessary, you can ensure that your electric sauna heater is properly installed and ready to use.

Types of Electric Sauna Heaters

There are three main types of electric sauna heaters:

  1. traditional Finnish sauna heaters
  2. infrared sauna heaters
  3. combination sauna heaters

Each type of heater has its own unique features and benefits.

Finnish sauna heaters use heated stones to provide a traditional sauna experience. Infrared sauna heaters use infrared technology to provide a more gentle and penetrating heat, while combination sauna heaters provide both traditional and steam generators for steam.

Factors to Consider When Choosing an Electric Sauna Heater

When choosing an electric sauna heater, there are several factors to consider to ensure that you select the right one for your needs.

Budget: Heater Pricing Ranges from $200 to $2000

Electric sauna heaters are available at a range of price points, typically ranging from $200 all the way to $2000. It’s important to establish your budget before making a purchase. It’s essential to strike a balance between your budget and the features and performance of the sauna heater.

Space Constraints

The size of your sauna room will influence the type and size of the electric sauna heater you choose. As a rule of thumb, you need approximately 1 kW of power for every 50 cubic feet of sauna space.

So, for example, a 6 kW heater would be appropriate for a sauna that is approximately 300 cubic feet in size. It’s important to select a heater that is appropriately sized for your sauna room to ensure that it can heat the space efficiently and effectively.

More Rocks Mean More Steam

Generally, the more rocks your sauna heater holds the more steam your sauna will produce. The heat and steam will also be “smooth” compared to fewer rocks.

Frequency of Use

Consider how often you plan to use your sauna when selecting an electric sauna heater.

If you plan to use it frequently, it’s essential to select a heater that can handle regular use and provide reliable performance over time. High-end models typically come with a longer warranty and may be a better option if you plan to use your sauna frequently.

If you’re using the sauna daily or almost daily, then an instant ready sauna heater might be the best option for you.

Personal Preferences

Finally, consider your personal preferences when selecting an electric sauna heater. Do you prefer a traditional Finnish sauna experience or the more gentle heat of an infrared sauna? Do you want a heater with digital controls or a more traditional dial? Considering your personal preferences can help you choose a sauna heater that you will enjoy using for years to come.
