About the C Series
The HeatMaster SS C-Series is a conventional outdoor furnace that burns coal or wood. In some states, state and federal regulations apply, so call us to ask about using wood in this furnace. Featuring an oval-shaped fire box, a removable ash pan and HeatMaster's industry-famous rocker grates, it outperforms the competition in features and ease of use.
It burns up to 30% less fuel than traditional outdoor boilers. Made in Canada, where they understand cold, it is built for long burns and easy ash removal.
