When I received my Faux Stone and white Lambert electric fireplace it came in two very large boxes. My husband and I were so excited that we immediately put it together. It will take two people to assemble. The assembly was very simple and only took less than about 30 minutes. We did use some Elmer's glue on the dowels just for added strength but it is not necessary. We set it up in our living room. Once we set it up we plugged it in and it is so amazing. Not only beautiful but also very efficient. It is difficult to heat my home because it is completely open concept. I have 4 very large rooms. Make sure to read ALL of the cautions and instructions in order to keep you and your family safe. We started heating right away. It took no time at all to heat all 4 rooms and then some. We got very warm very quickly. We left it set right at 70 degrees. About 20 minutes it was more than warm throughout the house. The temperature ranges from about 62 to about 85 degrees, and it will heat up in 4 degree intervals. The glass front stayed cool so I was not concerned with my pets laying in front of it. The white with the faux stone looks very classy and very real. It is so beautiful and comforting. I can adjust the thermostat, timer logs and the flame separately. Use all or just part of it's components at any given time. Heat, no heat etc. So easy to operate and my heat pump does not kick on when we use the fireplace. The booklet says the power is 120 volts/60Hz, 1500 watts, and 12.5 amps. The remote uses one battery, a CR2025, which is included. I love using the remote from anywhere in my room and it is so simple to work. The whole unit is so realistic and clean looking. Also with the attached 6 ft. electrical cord I am able to use it in nearly every room in my home. It will heat at least a 400 square foot area, and with my ceiling fan on low, I was able to heat most of my home with just the fireplace. This is perfect ! It measures at 45.75 wide, 15.75 deep and 40.75 in height. The mantle itself is constructed to hold up to 85 pounds and is 15.5 deep. Large enough to hold a television as well. The best part is that I can use this fireplace year round, just as a calming effect and also to actually heat my home.
