BWT, Installation and User Manual
The TyloHelo BWT is a passive steam generator that does not need a separate power supply as it utilizes the
radiant heat produced by the sauna heater elements.
It is an air humidifier developed for electric sauna heaters that allows you to enjoy your sauna with cabin
temperatures as low as 130°F to 150°F. This device will keep the air in the sauna room much more humid than
usual throughout the sauna session.
Being able to enjoy the warmth of the sauna at a lower temperature is based on the fact that air that is more
humid feels warmer because the airborne steam condenses on the skin. Breathing is also much easier at a lower
air temperature.
Installation:
The BWT vessel can only be installed in one of two
locations, shown in red to the right. Either between
elements 1 & 2 or between elements 5 & 6. Choose
your location based on ease of accessibility and to
minimize excessive reaching over the hot rocks to fill
the tank.
Removed the rock bar from the desired location by
removing the two retaining screws from each end of
the bar.
Slide the BWT vessel into the open cavity between the
elements, making sure that the two mounting tabs rest
fully on the support brackets on each side of the heater.
Place the BWT cover and Fill Cap/Fragrance cup on the
top of the BWT vessel to complete the installation.
Place the rocks into the heater, fully surrounding all
elements. I is ok to put rocks on top of the BWT cover
but leave the Fill Cap accessible.

Use: General
•Fill the BWT with clean, potable water. It is recommended that hard water with a high mineral content
not be used as it will result in a rapid limescale build-up.
oThe BWT tank will hold approximately 1.5 U.S. gallons of water but it is best to use no more
than 1 gallon when filling to prevent boil-over.
•The easiest way to fill up the BWT is to use a standard long-reach watering can. (Plastic is
recommended)
oPour the water through the open slots in the BWT cap.
•The small “cup” located on the edge of the filling cap is design to hold liquid fragrances.
oUse only water-based fragrance such as Rento Sauna Scent®.
oBe careful not to over-fill the fragrance cup.
•Turn the Laava heater on.
•The water in the BWT will begin to boil in about 12-15 minutes.
oYou will start to notice steam condensing on glass surfaces.
•You can start enjoying the sauna when it reaches temperatures of just 130-150°F.
oSee the Rule of 200, below.
•A full BWT can last an hour or more depending on the selected sauna temperature.
•While it is ok to use the Laava heater with the BWT empty, it is recommended to keep some water in the
vessel to minimize any potential deformity of the metal tank.
•The stainless steel of the BWT will turn brown over time and use. This is completely normal.
Note! Inspect the inside of the BWT at regular intervals. If you notice a lot of limescale on the bottom or
sides, remove the tank and clean it out. For stubborn build-up, use a solution of hot water and citric acid or
Opti-Clean® (available from your TyloHelo Dealer). Rinse well before re-installation.
Avoid filling the BWT when it is in use. Water splashed on the hot stones evaporates rapidly and
may cause burns. Do not pour water into an empty tank when the Laava heater is hot as the
steam may scald your skin.
Rule of 200:
A common formula used to determine the optimum temperature in a sauna is called the “Rule of 200”. Very
simply, take the displayed air temperature plus the humidity in the room. The sum should come close to 200,
which is a commonly accepted air temperature in many European saunas. The BWT will produce a constant
30% - 35% humidity so If the air temp is 140°F, then the air will feel like 175°F. Or, if you run your sauna at
170°F with BWT, your air will feel like it is 200°F. Adjust the sauna temperature to your desired setting.

The Many Different Ways to Enjoy Your Laava with BWT!
Dry Sauna:
•Fill the BWT up to about 1/3 of its capacity and start using the sauna when the displayed temperature
reaches about 150°F or above.
oA pre-humidified sauna will feel more comfortable than a dry one.
oWater can be sprinkled on the hot stones as usual.
Humid Sauna:
•Fill the BWT with 1 gallon of water and start using the sauna once it has reached 130°F.
oAfter about 10-15 minutes, water droplets will form on the skin.
oThe feeling of perspiration is caused partly by the condensation of water and partly by actual
perspiration. This creates a feeling of deep relaxation in the sauna.
oThe lower air temperature and humid air make it easy and pleasant to breathe in the sauna.
Fragrant Sauna: (continuous)
•Add water-based fragrance to the water that you will be using to fill the BWT. Experiment with smaller
amounts and add until you find the level you enjoy the most. Usually just a few drops are needed per
gallon of water.
oThe fragrance will continue to be remitted at a constant rate as long as there is water in the BWT.
Fragrant Sauna: (short term)
•Fill the BWT with clean, fresh water.
•Add a small amount of water-based fragrance to the fragrance cup.
•The essence will last about 5-10 minutes.
Salt Sauna:
•Fill the BWT with water
•Place a few large chunks of Himalayan salt (available for your TyloHelo Dealer) over the fill cap slots
oWhile the water is boiling, you will start to taste salt in the air.
Note: Using the salt method may require more frequent cleaning of the BWT tank and will leave a slight white
residue on the fill cap, which will not harm the BWT.
