Can I combine a water vapour fire with heating?

Absolutely. Many models come with an integrated electric heater of up to 2,000 watts, providing genuine warmth alongside the realistic flame effect.

How often do I need to refill the water tank?

Typically every 8–10 hours of use, depending on the model. Refilling is simple and can be done with regular tap water. Regular cleaning and descaling will help extend the appliance’s lifespan.

Are water vapour fires safe?

Yes – completely. There is no real flame or heat, so there’s no risk of burns or fire. This makes them ideal for homes with children and pets.

Can I install a water vapour fire in my existing fireplace?

In many cases, yes. Dimplex offers built-in units that fit neatly into existing surrounds, allowing you to maintain the traditional fireplace look while enjoying modern electric comfort and safety.

Is the water mist emitted from vapour fires harmful to health?

No. The sump and water tank of vapour fires are treated with Silver Biocide, an antimicrobial agent that inhibits bacterial growth by up to 99.99% (tested to ISO 22196 standard).

Q: How realistic is the flame effect?

Thanks to Dimplex’s patented Optimyst® technology, the flames look astonishingly real. The combination of ultra-fine mist and LED lighting creates depth and movement that closely mimic a genuine fire.

What is a Water Vapour Fire?

A water vapour fire is an electric fireplace that uses ultra-fine mist and LED lighting to simulate a lifelike flame effect. The result is a stunning 3D visual that looks like real fire – but without smoke, heat, or CO₂ emissions. A built-in water reservoir produces the mist that brings the flames to life.

What is a Water Vapour Fire?

A water vapour fire is an electric fire that uses ultra-fine water vapour and LED lighting to simulate a realistic flame effect. This creates a stunning 3D flame image without real fire, smoke, or CO₂ emissions. The water reservoir produces a mist that makes the flame effect visible.Benefits of a Water Vapour Fire:

No chimney or flue required
Safe for children and pets
Energy-efficient and eco-friendly thanks to the absence of combustion
Three-dimensional flames
The only electric flame technology suitable for see-through fires and room dividers
No smoke, odour, or harmful emissions

Drawbacks of Water Vapour Fires:

Water is required; this can be refilled manually, but some models can be connected directly to a mains water supply.
Electric fires with Optimyst technology need periodic maintenance, as water can cause limescale build-up.
