Optional Add-Ons

Bake Oven

A traditional white bake oven above the firebox. Flames do not pass through the chamber, allowing clean, even cooking from stored heat. Ideal for bread, pizza, and roasting.

 

Heated Benches


Add straight, wrap-around, or custom bench layouts to distribute radiant heat and increase thermal storage.

 

Custom Finish


Each heater is built and finished on-site. Common finishes: brick, natural stone, or plaster. Every system is unique to the home.
