Questions & Answers:

Is it Safe to Put Water on Electric Sauna?

Yes. If you’re worried about getting electrocuted by adding water to your sauna heater, take note of these few things:

  • Electric sauna heaters cannot handle water being poured on them. That said, your electric heater can handle a drizzling of water on them. This will boost your sauna experience by adding steam to your sauna and raising the humidity of your home sauna.
  • Pouring water on any electric device will cause it to short-circuit and poses a fire hazard.
  • A few splashes of water on your electric stove is enough. This also prevents your room and heater from getting overwhelmed.

How Do You Size a Heater?

The general formula is 50 cubic feet = 1 Kilowatt. Say for 300 cubic feet sauna rooms; you’ll need sauna heaters that are 6 Kilowatt.

Size a Sauna Heater


However, you need to consider that outdoor saunas built for outdoors will need an oversized heater.

What is the Difference Between An Electric and An Infrared Sauna Heater?

The biggest difference noticeable to those who have tried both kinds of saunas is the heat. If you’re sensitive to environmental heat, you may not enjoy your time in a traditional sauna.

That’s because traditional saunas usually maintain a high temperature of up to 195 degrees Fahrenheit.

Adversely, if you install an infrared sauna heater, you don’t need to raise the room temperature to notice its effects.

What Size Heater Do I Need for a Sauna?

Determining the appropriate size of a heater for a sauna requires careful consideration of several factors. The size of the heater depends on the volume and insulation of the sauna room, as well as the desired temperature and heat-up time.

The first step is to calculate the cubic footage of the sauna room by multiplying its length, width, and height. This measurement gives an estimate of the volume that needs to be heated. Generally, a sauna heater should provide around 1 kW of power for every 50 cubic feet of sauna space.

Insulation plays a crucial role in heat retention, so it’s important to assess the sauna’s insulation quality. Well-insulated saunas retain heat more effectively, allowing for smaller heaters. On the other hand, poorly insulated saunas may require larger heaters to compensate for heat loss.

The desired temperature is another key factor. Higher temperatures necessitate more power to achieve and maintain the desired heat level. For example, traditional Finnish saunas typically operate between 80°C (176°F) and 100°C (212°F), while lower-temperature saunas, such as infrared saunas, may require less power.

Heat-up time is also a consideration. If you prefer a sauna that heats up quickly, a more powerful heater might be necessary. However, if you’re willing to wait a bit longer for the sauna to reach the desired temperature, a smaller heater may suffice.

It’s worth noting that heater manufacturers often provide guidelines and recommendations based on sauna size and other parameters. Consulting these guidelines can be helpful in selecting the appropriate heater size.

Ultimately, the size of the heater for a sauna depends on the specific requirements and preferences of the sauna owner. By considering the sauna’s volume, insulation, desired temperature, and heat-up time, one can make an informed decision to ensure optimal heating and a comfortable sauna experience.

Things to Remember Before Shopping

There are many factors you need to think of before purchasing heating elements for your sauna.

For starters, what kind of sauna do you want?

There are a variety of sauna types:

  • Wood burning sauna
  • Dry sauna
  • Finnish traditional saunas
  • Gas Sauna
  • Infrared saunas

Size a Sauna Heater Design

Once you’ve determined which sauna type you’re looking for, you can start deciding which model is the best for you.

  • If you’re choosing an electric sauna heater, make sure it’s easy to use and made of stainless steel to achieve the best electric sauna.
  • For wet dry saunas, an electric stove that heats sauna stones is ideal.
  • A gas sauna is understandably more so meant for dry heating.

Are Harvia Sauna Heaters Good?

Alright, so yes, as with any product, it is not really fair to talk about the technical aspects without letting people try it out first and having a proper verdict about it. That being said, when it comes to harvia or balneumati or whatever other word for heat from natural springs, one thing is certain: it can easily rise to the level of “something that should be in everyone’s home!” The latest two of such reviews are about the new water heater from the famous French manufacturer “Vallair”: the garden2home harvia water heater. Each product from Vallair is a high-end affair, and their harvia water heater offers a wide array of functions and traits. This new machine takes things one step further and offers options and great features for both outdoor and indoor use.

How Hot Can an Electric Sauna Heater Get?

Considering that the average fridge here in the United States can cool off your milk to near freezing—and the average refrigerators—anything that’s near its boiling point must be hot. The average electric sauna works at a temperature of 240 °C/482 °F (the boiling point of water is 212 °C/469 °F). The only caveat is that as a heat source, sintering will work only if you start out near its highest point. These temperature figures seem to be based on the most basic purpose of a sauna—during the joints and other connective tissue of the body. If that’s your main goal, by all means, get yourself one of these to work on the joint issues.

But, if your main reason for using a sauna is to stay warm, then don’t be surprised if the temperature seems higher than you expected. Safety: Is Sintering Safe? We already touched on the heating element itself, which is one of the basic safety concerns in regards to any sauna. If the device isn’t completely water-tight and sealed, the heating element can quickly dry out. Many cheap electric sauna models don’t have watertight sealing, so if you accidentally step in the shower of the sauna with your foot.

Finlandia Flb-80 Sauna Heater

Finlandia Corporation introduced the very first “housewife-friendly” electric spa in the U.S. when it debuted its concept for a bathing suit-clad woman in the 1972 furniture catalog. The Finnish company’s ornately detailed “Solisto” sauna console lights up the fireplace room, where you can dine, read a book or take a nap in a post-shower “midday.”

By the 1980s, Finlandia’s basic model (above, from the 1970s) with a wooden base was about half the price of a modern Jacuzzi and a fraction of the price of a jacuzzi heat pump. The low-tech electric version (below) was less than half the price of a modern outdoor A.V. unit but, like most of these simple heaters, made do with only a single thermostat and a somewhat short wick.

Frequently Asked Questions

Do Sauna Heaters Use a Lot of Electricity?

Sauna heaters, while integral to creating the desired sauna experience, are not typically characterized by excessive electricity consumption. The power usage of a sauna heater depends on several factors, including its size, type, and duration of operation.

Infrared sauna heaters, known for their energy efficiency, generally consume less electricity compared to traditional electric or wood-burning heaters. Infrared heaters directly heat the occupants and surfaces inside the sauna, minimizing energy wastage. The power rating of sauna heaters varies, with smaller units typically ranging from 1.5 to 3 kilowatts (kW), while larger heaters may go up to 9 kW or more. The choice of heater size depends on the sauna’s dimensions and intended temperature range.

The actual electricity usage also hinges on how often and how long the sauna is in operation. Standard estimates suggest that an hour-long session in a mid-sized sauna with a 6 kW heater might consume around 6-9 kilowatt-hours (kWh) of electricity. However, this is a generalization, and actual consumption can vary based on specific sauna characteristics and usage patterns.

In essence, while sauna heaters do consume electricity, their energy usage is not exorbitant. Energy-efficient designs, such as those found in infrared saunas, contribute to a more sustainable and cost-effective operation, making sauna ownership an accessible and relatively economical indulgence.

How Do I Choose a Sauna Heater?

Selecting the appropriate sauna heater is crucial for optimizing your sauna experience, tailored to your specific preferences and sauna type. Various factors should guide your decision-making process, including sauna type, heating method, power source, desired features, and room size considerations.

Firstly, assess the type of sauna you have or intend to install, whether it’s a traditional (dry) sauna, steam sauna, or infrared sauna. Each type requires a heater tailored to produce the appropriate heat and humidity levels.

For traditional saunas, which rely on dry heat, options include electric heaters, wood-burning stoves, or gas heaters. Electric heaters are commonly preferred for their precise temperature control and easy installation. Wood-burning stoves offer a traditional sauna ambiance but necessitate regular maintenance. Gas heaters provide rapid heating but require access to a gas line.

Steam saunas require steam generators to produce steam by heating water. The size and capacity of the generator should match the sauna’s dimensions and desired steam output.

Infrared saunas utilize infrared heaters that emit radiant heat, penetrating the skin more deeply than traditional saunas. These heaters are typically electric and come in various forms, such as ceramic, carbon, or near-infrared heaters.

Consider the power source available for your sauna heater. Electric heaters are versatile, but ensure your electrical system can support the heater’s power requirements. Gas heaters need access to a gas line, while wood-burning stoves require a wood supply and proper ventilation.

Additionally, factor in room size considerations. As a general guideline, a sauna heater typically requires 1 kW to heat 50 cubic feet of room space. For instance, a 6’x7’x7′ sauna room would ideally need a 5 kW heater (252 cubic feet divided by 50 equals 5.04). Outdoor saunas or those built on outside walls may require an oversized heater to compensate for heat loss.

By carefully considering these factors and room size guidelines, you can select a sauna heater that enhances your sauna experience with efficient and reliable performance.
