Cozy Heat — Frequently Asked Questions

What size sauna stove do I need?
12kW stoves typically heat saunas up to 400 cubic feet, while 18kW models handle larger spaces up to 600 cubic feet. Consider your sauna dimensions, insulation quality, and desired heat-up time.
What's the difference between standard and thru-wall models?
Thru-wall stoves allow wood loading from outside the sauna room, keeping bark and debris out of your sauna space. Standard models are loaded from inside the sauna.
What are the different model types (OG, SW, Quattro)?
Each model features different designs and stone capacities. OG is the original design, SW offers side-wall configurations, Quattro provides four-sided heat distribution, and O models offer optimized heat patterns.
What type of wood should I use?
Use seasoned hardwoods like birch, oak, or maple. Avoid softwoods, treated lumber, or materials with paint or finishes. Wood should be dried to less than 20% moisture content.
Do I need professional installation?
Yes. Wood-burning sauna stoves require proper clearances, ventilation, and chimney installation per local building codes. Professional installation ensures safety and optimal performance.
What sauna stones should I use?
We offer both rounded olivine and traditional split-face sauna stones. Use stones sized 10-15cm for optimal heat retention and steam production.
