While all the Ecco Stoves are simple and quick to build the installation and in particular the chimney / flue system is key to getting the most out of your stove and ensuring it works correctly. Although Ecco Stoves weigh between 595-1764 lbs they can be installed in most locations due to the modular construction. If you don’t have a chimney, a twin wall insulated flue system can be used through or going up the outside of your property. All stoves must be installed to local state requirements.
