I think we'll be going for a Dimplex optimyst cassette... But not 100% decided yet as we need to modify an existing fireplace to 'hide' the mechanism under the fire. Jetmaster looks good from web. The problem I have is there is nowhere in France to see electric fires; eveybody is wood over here.
The thing about the optimyst I don't like is the need to replenish the water tank ( seems a fiddly job).
We almost went for a dimplex revillusion but backed out when a youtube video showed the reflection you get off of the flame screen. Not something the sellers videos show you.
It seems to me that fires that try to get the flames in the middle of the logs all use a reflective screen to achieve the effect. I don't want to see myself relected in the fire....
Like you, I want an infrared panel to simulate the heat from the fire, but I am still in google search mode...
