We purchased this fireplace because we demolished the brick chimney in our home but still had some floor tile in front of the old hearth surrounded by 60 year old wood flooring and an insert was the easiest way to get everything looking presentable again!
This unit is very slim (depth) so we didn't have to build out far to accommodate it. It looks great, very realistic! But, the heat output is pretty weak. For us it fills our need but do not buy if you actually need a decent heat source!
