Frequently Asked Questions

Masonry heaters are highly efficient and clean burning and when fired correctly convert over 80% of the energy to heat. Depending on firing their output ranges between 10,000 and 41,000 BTUs.

Because of their masonry heating principles and efficiency, the Environmental Protection Agency in the United States exempts masonry heaters from their regulations. Refer to their policies on their web-site under

To protect from sparks and embers use any UL or ULC listed Type 1 hearth board or any other non- combustible material. In the US the floor protection must extend continuously from the door opening at least 16” and 8” from the sides of a the door opening and 2” under the chimney connector.
