What is a water vapor fireplace?
Come visit and experience it yourself!
A water vapor fireplace, known as an opti-myst or cassette fireplace, is an innovative way to add atmosphere and warmth to your living room. These fireplaces use water vapor to create a realistic flame effect, making it seem like there is a real cozy fire burning.
The built-in water vapour fireplace for every application
The Cassette offers endless possibilities to bring atmosphere into your home in a simple and stylish way. This innovative water vapour technology is ideal as an alternative to a traditional wood or gas fireplace. You can easily place the cassette in an existing fireplace opening with a matching Xaralyn basket cassette.
But the Opti-myst is also perfect for those who want to get started themselves: build it into your own TV cabinet, cupboard or a custom-made project. Simply make a recess in your furniture, place the cassette water vapour fireplace and plug it into the socket. Plug & play doesn't get any easier than this. As long as there is power nearby, you can really do anything with it.

Reasons to choose water vapor fireplaces
If you are looking for an atmospheric and cozy addition to your living room, then a water vapor fireplace is definitely worth considering. No hassle with flues or gas connections, but simply enjoy a cozy and warm atmosphere in your home. With a water vapor fireplace you really bring a piece of coziness into your home!
Realistic fire image - how the light projection works
In the Opti-Myst water vapour fireplace, water is evaporated by means of an ultrasonic evaporator. This water vapour is not hot and is illuminated with lamps, making the water vapour look like flames.
Pet & Child Friendly Fire
The fine water vapour combined with light projection creates an imitation of a burning fireplace. The opti-myst does not give off heat making it pet and child friendly, perfect for any living space.
Easy to Install
A cassette water vapour fireplace is easy to place in a piece of furniture. No flue or chimney is needed. This makes the fireplace very attractive for apartments or studios, for example.
Benefits of Opti-myst Water Vapor
Realistic flame image
The power of a water vapour fireplace lies in its innovative technology. The use of water mist and lighting creates a three-dimensional flame image that is barely distinguishable from real fire. The soft, flickering light and the rising "smoke" ensure a lifelike fireplace experience - without fire, smoke or smell.
Operate with a remote control
With the supplied remote control you can easily operate the fireplace from the couch. Switching on and off, adjusting the flame height or activating the heating (for models with heating) can all be done with one push of a button. This way you combine atmosphere with ultimate ease of use.
Adjustable brightness
Every room requires a different atmosphere. That is why most Opti-myst fireplaces are equipped with a function to adjust the brightness of the flames. This allows you to decide whether you want a subtle glow or a lively play of flames in your interior.
Long burning time
Another advantage of water vapour fireplaces is their efficient use of water. On average, a fully filled reservoir burns for up to 7 hours. After that, you can simply refill it with tap water – environmentally friendly and user-friendly.
Maintaining a water vapor fireplace
A water vapor fireplace requires little maintenance, but regular simple actions are important for proper functioning and longevity. Think of refilling the water reservoir, replacing the evaporator and cleaning limescale.
Refilling the water reservoir
A water vapour fireplace works on the basis of a removable watertank. This tank provides the mist that, together with the lighting, forms the realistic flame pattern. On average, a full tank lasts for about 6 to 7 hours, depending on the model and the set flame height. You can easily refill it with tap water. No special water is required, although soft water or filtered water can extend the life of parts.
Replace the evaporator in time
The water mist is generated by an ultrasonic evaporator. This small but essential part converts water into fine mist. Depending on how often you use the fireplace, the evaporator lasts an average of 6 to 12 months. At Xaralyn you can choose an original replacement unit or a qualitatively equivalent copy of our own house brand. Both options create a beautiful flame effect.
Prevent problems caused by limescale
In some regions, tap water is relatively hard, which means it contains more lime. Limescale deposits pose a risk to the operation of the evaporator and other parts of the fireplace in the long term. Fortunately, this is easy to prevent. Check regularly whether limescale is visible and clean the parts if necessary. Use a soft cloth and a mild descaling agent or cleaning vinegar. By carrying out this maintenance regularly, your water vapour fireplace will continue to work safely, beautifully and efficiently.
Different options of water vapor fireplaces
Below we have highlighted several options for you to help you make the right choice.
Dimplex Cassette - atmosphere without heating
is the perfect choice if you are looking for a fireplace that purely creates atmosphere. Thanks to the advanced Opti-myst technology, you can enjoy a lifelike flame effect that is almost indistinguishable from a traditional wood fire. This cassette is designed to create a cozy ambiance, but does not emit any heat itself. Ideal for modern homes where atmosphere is more important than additional heating. The lack of a heating function also makes this fireplace more energy-efficient and safer to use, also in households with children or pets.
Cassette with metal top plate
A striking trend in modern interiors is the water vapour fireplace with a sleek metal top plate. This version gives a minimalist, contemporary look and allows a wide strip of dancing flames to come into their own. Due to the neutral look, this style fits perfectly in modern living styles. For those who still want to add some extra character, there is the possibility to add decorative elements such as wood or stones. This creates an impressive fireplace image that is both stylish and atmospheric.
Cassette with classic wooden bed
Lovers of a traditional fireplace look will be attracted to the version with a classic wood set. This version is equipped with realistic-looking logs that do not get hot and are therefore completely safe. The log set gives the illusion of a crackling wood fire, without having to drag logs or deal with smoke and soot. Moreover, it is practical in use: the wood decor is easy to remove to refill the water reservoir. This option combines the charm of the past with the ease of use of today.
Xaralyn Albany with heating and sliding drawer
Do you want to enjoy atmosphere and warmth? Then the Xaralyn Albany is an excellent choice. This luxurious water vapour built-in fireplace not only has a realistic flame pattern with glowing logs, but is also equipped with electric heating. The Albany offers the best of both worlds: the visual experience of an authentic fireplace and the comfort of a pleasant temperature. This fireplace is often combined with a mantelpiece from the Xaralyn collection, but can also be built into a wall or custom-made furniture. Thanks to the integrated sliding drawer, the water reservoir is easily accessible.

Why a water vapor fireplace is the ideal choice
Create Atmosphere and Warmth
- Environmentally friendly: A water vapour fireplace does not emit any harmful substances and thus contributes to cleaner air and a healthier environment.
- Safety: A water vapor fireplace is safer than traditional fireplaces because there is no open flame. This reduces the risk of fire and carbon monoxide poisoning
- No smoke or odor: Because there is no combustion, there is no smoke or odor released by a water vapor fireplace. This ensures clean and fresh air in the home
- Easy to install: A water vapor fireplace does not require a flue or gas connection, making installation quick and easy
- Versatility: A water vapor fireplace can be installed in any room in the home, as it does not require a chimney or flue. This makes it a versatile choice for both new and existing homes
Affordable and Efficient
A water vapor fireplace is not only a stylish addition to your interior, but also a surprisingly affordable choice in the long term. The annual costs are limited to tap water - depending on how often you use the fireplace - and the replacement of the evaporator approximately once a year. This makes the consumption very efficient and affordable compared to traditional fireplaces.
With a classic wood fireplace, the costs quickly add up due to the purchase of firewood and the annual cleaning of the chimney. These recurring maintenance and heating costs are completely unnecessary with a water vapour fireplace. In addition, you do not have to take into account storage space for wood or soot formation in the house.

FAQ About water vapor fireplaces
Read below
The Opti-Myst or water vapor fireplaces create a flame image by projecting light on ultra-fine water vapor. The water vapor is generated by an ultrasonic evaporation with an evaporator, after which the water vapor rises by means of the heat of halogen lamps or a heat coil.
Water vapor fireplaces are very maintenance-sensitive due to the combination of water (lime) and electricity.
It is recommended to regularly clean the evaporator and watertank of the Opti-Myst fireplace. The evaporator will last between 6-12 months with normal use and must then be replaced.
Using water with less lime and regular cleaning will extend the life of the evaporator.
The water vapor of the Opti-Myst fireplace mainly increases due to the addition of heat. This heat can come from a heating coil or from halogen lamps.
In the case of using LED lamps there is a heating coil in the Opti-Myst. In case of using halogen lamps, this heating coil is not necessary.
The energy consumption of the halogen lamps is less than the consumption of LED lamps in combination with a heating coil.
