The Cozy O is the circular rim design variant of the Cozy Heat range. Where the base Cozy stove has a trilateral (three-sided) form, the Cozy O features an innovative circular rim that gives the heater a softer, more rounded visual profile and enhances heat distribution across the stone mass surface by presenting the stone load in a circular rather than angular container. The same 5mm stainless steel flame cutter, three-stage combustion system, 25-40% firewood reduction, and German EN 15821:2010 certification apply to every model in the Cozy Heat range, including the O. The choice between the Cozy and the Cozy O is purely aesthetic - the O is for buyers whose sauna room design calls for a rounder, more organic form over the base model's angular lines.\u003c\/p\u003e\n\u003ch4\u003eThe circular rim design - what the O brings to the sauna room\u003c\/h4\u003e\n\u003cp\u003eThe defining visual characteristic of the Cozy O is its circular rim - the outer stone containment ring that gives the heater its name and its silhouette. Rather than the straight-sided angular enclosure of the base Cozy stove, the O presents the stone mass within a continuous curved border that reads as softer and more sculptural in the sauna room. Cozy Heat states that the circular rim not only enhances the heater's aesthetic appeal but also ensures efficient heat distribution throughout the sauna space - the curved geometry of the rim promotes more even radiant heat output from the circumference of the stone mass compared to a flat-sided container that concentrates radiation at the face panels. For sauna rooms with rounded or organic design elements - curved bench ends, rounded window openings, or natural material surfaces that call for softer forms - the Cozy O integrates more naturally than the standard Cozy model's angular profile.\u003c\/p\u003e\n\u003ch4\u003eSame technical foundation as every Cozy Heat stove\u003c\/h4\u003e\n\u003cp\u003eThe Cozy O PKG shares every technical specification with the base Cozy PKG. The flame cutter is 5mm stainless steel. The combustion system is three-stage: primary air through the fireplace grate, secondary air directed through channels to the mid-chamber, and tertiary air through ceiling pipes to the upper fire chamber - burning the flue gases themselves as a third combustion stage for higher efficiency and lower emissions. The result is 25-40% less firewood consumption than comparable stoves, up to 6x cleaner smoke gases, and 73.9% thermal efficiency at 12kW and 81.3% at 18kW. German BlmSchV DIN EN 13240 Level 2 and EN 15821:2010 certification confirm these figures against the most demanding European standard for wood-burning appliances. A chimney installation is required and sold separately.\u003c\/p\u003e\n\u003ch4\u003e12kW or 18kW - and the stone load that comes with each\u003c\/h4\u003e\n\u003cp\u003eThe 12kW Cozy O covers rooms from 210 to 423 cubic feet with a minimum stone load of 265 lbs. The 18kW covers 317 to 635 cubic feet with a minimum of 353 lbs. Both stone loads are included in this package at checkout with the appropriate quantity for the selected output level. The two output ranges overlap between 317 and 423 cubic feet. In this overlap zone, 12kW is appropriate for well-insulated wood-walled rooms; 18kW is appropriate for rooms with glass, tile, or masonry surfaces that reduce effective heating capacity. A chimney of the correct specification must be planned and installed before the stove is delivered.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eWood-burning sauna stove package with innovative circular rim design - available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft), select at checkout.
