Pros and cons

Pros

Flame-only operation allows the visual effect to be used without running the heater.
Two heat settings provide a choice between 1kW and 2kW output.
Water-vapour flame effect is a distinct alternative to a conventional LED-only flame display.

Cons

The water tank requires periodic refilling, and the manufacturer says the Optimyst transducer may need replacement over time.

What to know before buying

Listing details to confirm

The listed dimensions read 39D x 62W x 660H centimetres, because the height figure appears unusually large relative to the other listed measurements, confirm the intended measurements with the selected listing before checking room fit. The product description also mentions a remote control, but the package contents are not specified here.
