The Opel is our most popular fireplace. Part of the growing Opel family, the Opel 2C is a catalytic fireplace with elegantly shaped double doors. The Opel’s catalyst burns off harmful emissions and increases efficiency when the fire is burning at low temperatures. You get less creosote and more heat from your fire at low to medium burn rates. As a result, less fuel goes up your chimney in the form of smoke. The technology in the Opel is the result of over 30 years’ of experience in making high efficiency fireplaces. Popular Science Magazine recommended the Opel for its efficiency and emissions reduction. Our engineers have refined this technology over time, making the Opel what it is today.
