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 Watervapour Fireplace?

A watervapour fireplace, or Dimplex Optimyst fireplace, uses ultrasonic technology to create a fine mist that is illuminated by LED lights, producing highly realistic flame and smoke effects. Unlike traditional fireplaces that burn wood or gas, watervapour fireplaces use only water and electricity, making them an eco-friendly and low-maintenance option.

Installation and Maintenance

Installing a water vapour fire is simple – all you need is a mains socket and clean water. Cassettes and built-in models require additional ventilation to operate correctly. Models with heating will naturally use more electricity. To keep your fire in top condition, regularly refill the water tank, clean the unit, and descale it when needed.
