Throughout Canada and the United States, Temp-Cast masonry heaters are installed in accordance with local and national building codes as site-built masonry fireplaces. In addition, Temp-Cast heaters have been accepted as clean-burning heaters by the Environmental Protection Agency in the United States.
However, due to localized emissions problems, some state and local governments require additional testing to ensure that solid-fuel appliances comply with their particular regulations for clean-burning. Temp-Cast wood-fired masonry heaters have received approval in three of the most difficult jurisdictions in which to obtain acceptance to date: the State of Colorado , San Luis Obispo county in California and the State of Washington.
