YOUR OUTDOOR BARREL SAUNA TEMPERATURE GUIDE

We know from experience that if you want to get your sauna as hot as possible (or, at least make it more efficient), there are a few things you can do to get it to that satisfactory sauna temperature level. So how do you go about it?

 

We have compiled a list of factors to ensure your outdoor barrel sauna gets to the perfect sauna temperature. And there are two major ways you can improve the temperature of your sauna: covering it and enhancing your heater. The tips we share here will work for both electrical and wood-burning heaters.

Read on to learn how to improve the temperature of your outdoor barrel sauna with all the options available today.

Increase Your Sauna Temperature By Covering It 

Outdoor barrel saunas don’t need insulation as they are built for the outdoors!  However, covering the top is a great alternative. Some saunas offer various options. The following is a list of options you can use to cover your sauna.

Rain Jacket

A rain jacket is a great option. Such an option ensures you protect your sauna from heavy loads of rain or snow, making it easier to heat up to higher temperatures. It works by offering benefits such as:

• It’s removable

• You can choose different colors

• Keeps moisture out

• UV resistant

• Waterproof

Corrugated Metal Roof

You can easily access this at any local hardware store.  

Roof Shingles

These are individual shingles that may take longer to add when assembling your sauna, but they do look quite handsome on the finished product! Shingles also allow you to control the amount of space you want to cover. You can get them in different colors and styles to suit your preferences.

Covered Awning 

One of the great things about this option is you get to fully customize your cover’s appearance. You can build your own or use a pre-existing structure like an awning or underneath your second story porch, 

Extra Sealant     

If you have drafts or leaks in your sauna, you can use the steps below to seal any leaks within your sauna:

• Start by checking the door hinges to ensure they don’t slip. Use a piece of leather stripping to seal unnecessary spaces around your door.

• Make sure you add as many wooden staves as possible. Ensure all bands are tight.

• Check the window and make sure it doesn’t leak.

• Make sure there aren’t any spaces that may cause a leak.

  
  

Increase Your Sauna Temperature By Enhancing Your Heater 

The main factor that affects your sauna temperature is the heater. Both wood-burning and electric heaters reach a maximum of 195 degrees Fahrenheit. Take note that the type of stones, wood you use, and size of  the heater affects the sauna’s ability to produce and retain heat. Let’s take a look at the heating options for an outdoor barrel sauna and their advantages and disadvantages.

 

The size of your sauna heater is crucial to the outdoor barrel sauna’s performance. Large sauna stoves allow you to reach the ideal sauna temperature more quickly, but they might take up more internal space. Smaller heaters might fit nicely, but may take longer to warm your sauna space.  When it comes to what you prefer, the choice is yours! With every sauna product, we have recommendations for heaters based on the sauna size, but you’re welcome to increase the KW or opt for a different heater altogether. 

The following are tips to ensure you size your heater properly:

• The majority of saunas have a ceiling height of 7 feet or lower. Taller saunas need different heating requirements.

• Every 45 cubic feet in the sauna’s interior requires 1 KW of heater power

• For every 10.75 square feet of uninsulated wall, increase the volume by 42 cubic feet.

• Try increasing the size of your heater if you live in a cold region. Make sure the increase in size doesn’t affect your measurements.

• The majority of outdoor barrel saunas need a heater with a rating of 5 to 8 KWs.

Wood-burning Heaters

For starters, wood-burning heaters are cheaper than their electric counterparts. Apart from eliminating the hassle associated with electric wiring, they also give an authentic spa feel. On the downside, they make it harder to control temperatures, take more time to reach the desired temperatures, and require a chimney. 

Now, when it comes to the type of wood you're burning, this can also have an effect on your sauna temperature. When selecting wood logs for your heater, opt for wood types that are seasoned, clean, and easily accessible. Never go for wood that is freshly cut, stained, painted, or has broken knots. 

Softwoods are the best option when you are starting your fire. Examples of great softwood options are spruce, fir, redwood, cedar, and pine. Hardwoods burn slower making them a great option for fuel. Take note that they are a more expensive option. Examples of hardwood options are birch, poplar, cherry, walnut, maple, and oak. 

For a better heating experience, opt for an inside feed. This means that you “feed” the heater wood from inside the sauna, rather than from outside. And inside feed provides better ambiance and is more convenient.

Pros of the Wood-Burning Stove:

• No need for electrical wiring - can work off-grid!

• Aromatically pleasing

• Affordable

• Authentic feel

  
  

 Cons of the Wood-Burning Stove:

• Wood may be costly

• Takes longer to heat

• Harder to control temperatures

• Requires  a chimney kit

  
  

Electric Heaters

Electric heaters offer more convenience, and can be programmed or used with Wifi to heat your outdoor barrel sauna quickly. They are convenient to use and some have a safety feature for automatically resetting the heater after 1 hour. 

Pros of the Electric Heater:

• 1-hour automatic reset

• Options for Pre-programming and Wifi 

• Quick heating

• Convenient - turn them on with a flip of a switch

  
  

Cons of the Electric Heater:

• Only works when there is power

• Will need a licensed electrician to help you hardwire it 

• Affects your electricity bill

Additional Factors That Can Affect Your Sauna Temperature

The Vents

Some saunas come with two vents. One of them is by the ceiling and it’s designed for exhaustion. The other is underneath the heater and it’s designed to pull in the fresh air. The following are recommendations for using your vents:

• Warm up your sauna heater with your vents open. This ensures the high-limit sensor is not activated. 

• To avoid cold air from getting in your sauna’s bottom, keep the corks in the drain stave

• Close the vents when you are using the sauna. Open them up if you feel the air is too stuffy. 

  
  

The Humidity

Controlling your humidity levels is one of the advantages of using a traditional outdoor wood sauna. To create a burst of steam, add more water to your stones. Naturally, wet heat and dry heat are the same when it comes to their temperature. However, wet heat feels hotter to your body than dry heat. 

 

Avoid dumping water on the sauna stones. Alternatively, find a way to drizzle water evenly on them. You can try using a bucket and a ladle for the best results.
