The new Solution 2.3 model produces average particulate emissions of 3.9 g/h and is EPA Washington state approved. It is often the choice of informed consumers who know the secrets of wood heating. Its firebox is 21 inches wide and 16.5 inches deep, so logs can be placed side-to-side or front-to-back. Like its smaller cousin, Solution 1.8, it has an ingenious door overlay system that allows you to choose between a black or brushed nickel finish. All other options - such as choice of legs or pedestal, variable speed 130 CFM fan and air mate - are also available. Although the firebox is roomy, Solution 2.3 boasts a balanced design that combines a decorative touch with serious heating power.
