For the price, I am very satisfied mirt the fireplace. The assembly is very simple. With the supplied spacers can let the wallpaper behind the fireplace. In the tank can fit about 300 ml. The range for about 3 hours. I think that's quite sufficient. Because I want to leave no ethanol in you combustor overnight. Clear but each of these must be the fire no fire wood fireplace replaced. It lacks the crackling. What I noticed is when ethanol is this - I have initially started with 96% ethanol. But was very disappointed with the small flame. The flame was only about 5 cm tall. Now I use 99% ethanol (Price per liter 2,00 direckt at producer I pay now) and have a nice high flame (approx 15 cm - 20 cm). To warm up the room I have to say that it works well. I have the fireplace in the living room with about 25 m² living space and a ceiling height of 2.50 m. I can turn off the radiators in the room. The chimney shaft to keep the room temperature at konztanter. So much for my experience with the fireplace.
