Dimplex Opti-myst Cassette 500 Projects - Automatic Water Vapour Burner
Cassette 500 Projects Opti-myst Hybrid Automatic Water Vapour Burner
Here we present the Dimplex Opti-myst Cassette 500, a 50 cm wide unit designed specifically for DIY projects where you want to create your own Opti-myst water vapour fireplace.
Opti-myst technology, developed by Dimplex, uses water vapour and LED lights to create 3D flame effects. This results in a stunning flame illusion, which is why these fireplaces are often referred to as Opti-myst, Hybrid, or Water Vapour fireplaces.
The Dimplex Cassette 500 comes with a standard black metal top plate. However, you can also purchase a set of decorative logs that can be placed on top of the cassette to enhance the realistic appearance of the flames.
Hybrid fireplaces, such as the Dimplex Cassette 500, are highly versatile and can be installed in a variety of locations, as they do not require a connection to a flue system. All that is needed is an electrical outlet. The Dimplex Cassette 500 does not generate heat, making it ideal for modern homes where additional heat is not required, but you still want to enjoy the cozy ambiance of a fireplace.
Additionally, the Cassette 500 has a built-in sound module that can create sparkling fireplace sound effects.
Requires Fixed Water Connection
Cassette 500 Project requires a connection to a fixed water supply.
Being connected to a fixed water supply means that the cassette is automatically refilled with water when necessary. You will never have to manually refill the cassette with water - it happens completely automatically!
The model with automatic water connection can also be used with an external water container and a special water pump. Please contact our customer service for more information on this.
If you don't have the option to connect Cassette 500 to a fixed water supply, you should choose the Cassette 500 Retail edition here.
