Imagine a gas insert that enable you to enjoy a gorgeous, glowing fire without losing heat out of your chimney. These inserts are designed to transform virtually any masonry or zero clearance (metal) fireplace into an efficient source of heat. Traditional open fireplaces can have efficiency ratings as low as 15%, and depending on the condition, can actually draw the heat out of your home for a net heat loss. FireplaceX and Lopi gas inserts represent an extensive range of unique, exciting hearth products that are exceptionally built and offer exquisite handcrafted details along with exclusive, award-winning features and designs found nowhere else.
