With its extra large window providing a widescreen view of the incredibly life-like flames within, this beautiful cast iron stove shares the design of ESSE’s most popular wood-burning stove. But in terms of instantly controllable warmth and energy-efficiency, it’s everything you’d expect from a 21st century gas appliance . . . Capable of generating a mighty 4.9 kW of heat, at an impressive 78.3% fuel-efficiency rate, the Conventional gas 200 comes into its own when it’s seriously cold outside.
