Cozy Heat is an Estonian brand that has taken the ancient craft of wood-burning sauna stoves to a new level of efficiency and environmental performance. Wood-fired sauna stoves produce a qualitatively different heat from electric heaters - the combustion cycle creates an atmosphere that many sauna bathers find softer, more enveloping, and more satisfying than electrically heated air - and the Cozy Heat stove is engineered to deliver that experience with 25-40% less firewood than comparable stoves, earning Germany's highest certification standard for wood-burning stove emissions. No electrical connection is required. A chimney installation is required - sold separately.\u003c\/p\u003e\n\u003ch4\u003eWhy wood-fired heat is different from electric heat\u003c\/h4\u003e\n\u003cp\u003eAn electric sauna heater warms the room by heating elements and stones to temperature and maintaining them there indefinitely at the press of a button. A wood-fired sauna stove builds heat progressively over a 1 to 2-hour firing cycle, creating a live fire inside the stove body that radiates heat through the firebox walls, heats the stone mass above, and produces a naturally convecting warm air movement that is distinct from the forced or passive convection of electric heaters. The sauna session begins when the fire is lit and the room temperature rises through the firing cycle - bathers who prefer the ritual of wood-fired sauna, the smell of burning wood in the sauna room, and the visual warmth of the fire visible through the glass door are choosing an experience that no electric heater can replicate. The Cozy Heat stove's three-stage combustion system - primary air through the grate, secondary air to the mid-chamber, tertiary air through ceiling pipes - burns the flue gases themselves as a third combustion stage, producing less smoke and more heat from each load of wood.\u003c\/p\u003e\n\u003ch4\u003e12kW or 18kW - room size determines the choice\u003c\/h4\u003e\n\u003cp\u003eThe 12kW Cozy Heat covers rooms from 210 to 423 cubic feet and requires a minimum stone load of 265 lbs. The 18kW model covers rooms from 317 to 635 cubic feet and requires a minimum stone load of 353 lbs. The two output ranges overlap between 317 and 423 cubic feet. For rooms in this overlap zone, Sauna Supply Company recommends choosing the 12kW for faster heat-up times and lower wood consumption in standard wood-walled rooms, and the 18kW for rooms with significant cold surfaces - glass doors, tile floors, concrete or masonry walls - that absorb heat and require more output to compensate. A chimney of the correct diameter and height is required for both models and must be planned and installed before the stove can be used.\u003c\/p\u003e\n\u003ch4\u003e5mm stainless steel flame cutter - the critical durability specification\u003c\/h4\u003e\n\u003cp\u003eThe most thermally stressed component of any wood-burning sauna stove is the flame cutter - the internal baffle that direct flame from the firebox strikes as combustion gases rise toward the flue. In lower-quality stoves, this component is made from thin steel that warps, cracks, and eventually fails under sustained heat cycling. In the Cozy Heat, the flame cutter is fabricated from 5mm stainless steel - substantially heavier than the industry norm - giving it the thermal mass and corrosion resistance to withstand years of firing cycles without distortion. The stove body itself is steel construction. The floor-standing design requires no wall mounting; the stove sits on the sauna floor and connects to the chimney via a top flue outlet.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eWood-burning sauna stove package available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft) - select at checkout.

Estonia is a country where wood-fired sauna bathing is embedded in national culture - not a luxury product for those who can afford it, but a regular part of daily and weekly life for ordinary households. The Cozy Heat stove is made in this context: it is built to the functional standards of a working sauna country, not to the marketing standards of an imported premium product. The 5mm stainless flame cutter, the three-stage combustion, and the German environmental certification are engineering decisions rather than marketing distinctions.

For a standard 300-350 cu ft wood-walled sauna room, the 12kW is the practical choice. For the same room with a glass wall or tile floor, the 18kW provides the headroom to compensate.

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.

The Cozy OG is the contemporary trilateral variant - it shares the three-sided body form of the base Cozy but refines it with clean lines and graceful curves that give the stove a more polished, contemporary visual character. Where the base Cozy's trilateral form is functional and direct, the OG's curves soften the transitions between the three faces, producing a stove body that is simultaneously architectural and organic. Every technical specification - the 5mm stainless flame cutter, three-stage combustion, 25-40% firewood reduction, and German EN 15821:2010 certification - is identical across all Cozy Heat models. The OG is for buyers who want the three-sided Cozy form with a more refined, curved execution.\u003c\/p\u003e\n\u003ch4\u003eContemporary trilateral design - clean lines and graceful curves\u003c\/h4\u003e\n\u003cp\u003eThe Cozy OG body features the same innovative trilateral (three-sided) geometry as the base Cozy, but with a contemporary execution: the edges and transitions between the three faces are characterised by graceful curves that soften the stove's silhouette without abandoning the clean-lined, architectural quality of the trilateral form. Cozy Heat describes this as \"clean lines and graceful curves\" - a design language that sits between the base Cozy's more utilitarian angularity and the Cozy O's fully circular rim. The OG reads as the most refined version of the trilateral form in the Cozy range - appropriate for sauna interiors where the stove is intended to be a design feature in its own right, not simply a functional heating appliance placed against a wall. For buyers who have viewed both the base Cozy and the Cozy O and prefer a three-sided form with more considered design detailing, the OG is the appropriate choice.\u003c\/p\u003e\n\u003ch4\u003eSame proven Cozy Heat engineering in every model\u003c\/h4\u003e\n\u003cp\u003eThe OG shares every technical specification with the base Cozy PKG and the Cozy O PKG. The flame cutter is 5mm stainless steel - the most thermally stressed part of the stove, built to resist the warping that thinner steel develops under years of sustained heat cycling. The combustion system is three-stage: primary air through the fireplace grate, secondary air through mid-chamber channels, and tertiary air through ceiling pipes that burn the flue gases themselves as a final combustion stage. The result is 25-40% less firewood than comparable stoves, up to 6x cleaner smoke gases, and 73.9% thermal efficiency at 12kW and 81.3% at 18kW. The German BlmSchV DIN EN 13240 Level 2 and EN 15821:2010 certification confirm all these figures against Europe's most demanding standard for wood-burning appliances. A chimney installation is required and is sold separately.\u003c\/p\u003e\n\u003ch4\u003e12kW or 18kW with the correct stone load included\u003c\/h4\u003e\n\u003cp\u003eThe 12kW Cozy OG covers rooms from 210 to 423 cubic feet with a minimum stone load of 265 lbs included at checkout. The 18kW covers 317 to 635 cubic feet with a minimum of 353 lbs. The overlap between 317 and 423 cubic feet gives buyers in this range a choice: 12kW for well-insulated wood-walled rooms where faster heat-up and lower wood consumption are priorities; 18kW for rooms with glass, tile, or masonry cold surfaces that require more output to compensate for increased heat absorption. Each natural stone is unique in shape and size - purchasing an additional box of stones allows selection of the best-fitting pieces for the stone cavity of the OG's particular geometry.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eWood-burning sauna stove package with contemporary trilateral design - clean lines and graceful curves - available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft), select at checkout.

The SW is the most dramatically different design in the Cozy Heat range: where the base Cozy, Cozy O, and Cozy OG are all variations on angular or curved three-sided or rimmed forms, the Cozy SW is a sleek, contemporary cylindrical column. Its smooth curves create a sense of elegance and visual drama that sets it apart from every other model in the Cozy lineup. Cozy Heat describes it as a \"dramatic\" stove - and the cylindrical silhouette supports that description, making the SW the choice for sauna rooms where the stove is intended to be the dominant visual element. Every technical specification is identical to the other Cozy models: the same 5mm stainless steel flame cutter, three-stage combustion, 25-40% firewood reduction, and German EN 15821:2010 certification.\u003c\/p\u003e\n\u003ch4\u003eSleek cylindrical design - the most dramatic form in the Cozy range\u003c\/h4\u003e\n\u003cp\u003eThe Cozy SW body is a continuous cylindrical column - smooth, rounded, without angles or visible flat faces. Cozy Heat describes the smooth curves as contributing to both the stove's elegance and its heat distribution, with the cylindrical geometry ensuring the sauna reaches and maintains the desired temperature efficiently. In a sauna room context, a cylindrical stove reads as a pillar of heat and fire - a sculptural element that commands attention rather than receding into the wall. The glass door lets the fire be seen within the cylinder, reinforcing the dramatic quality of the SW's presence. For sauna rooms designed around minimalist Scandinavian aesthetics, modern Nordic interiors, or any space where a cylindrical form complements the architecture, the SW is the standout choice in the Cozy lineup. It is comparable in its visual impact to the Harvia Cilindro in the electric heater range - both are pillar-form stoves that make the stone mass and fire the focal point of the room.\u003c\/p\u003e\n\u003ch4\u003eSmooth curves - efficiency and aesthetics working together\u003c\/h4\u003e\n\u003cp\u003eThe cylindrical geometry of the SW is not purely decorative. Cozy Heat states that the smooth curves contribute to optimized heat distribution, ensuring the sauna reaches and maintains the desired temperature. A cylindrical stove body presents the same radius of curvature to the room from all radial directions - unlike a flat-faced triangular or rectangular body that radiates heat more strongly from its faces and less from its edges and corners. The continuous curved surface of the SW distributes radiant heat more uniformly around the full circumference of the stove body, complementing the convective heat that rises from the stone mass above. The same three-stage combustion system - primary, secondary, and tertiary air injection - operates within the SW cylinder as in every other Cozy model, delivering 25-40% firewood reduction and 73.9% or 81.3% thermal efficiency at 12kW and 18kW respectively.\u003c\/p\u003e\n\u003ch4\u003eSame Cozy Heat engineering - 5mm stainless flame cutter\u003c\/h4\u003e\n\u003cp\u003eThe flame cutter in the Cozy SW is fabricated from 5mm stainless steel, as in every model in the Cozy range. This is the single most important durability specification in a wood-burning sauna stove: the flame cutter takes direct, sustained contact with the firebox flame and must resist warping under years of heat cycling. The 5mm stainless construction is substantially heavier than the industry standard for this component and is what gives Cozy Heat stoves their longevity advantage over lower-specification competitors. A chimney installation of the correct diameter and height is required and is sold separately. The SW must not be connected to a shared flue system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eWood-burning sauna stove package with sleek contemporary cylindrical design - available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft), select at checkout.

The Quattro is the four-sided model in the Cozy Heat range - its name meaning \"four\" - and the most architecturally minimal of all the Cozy designs. Where the base Cozy and OG are trilateral, the O is circular-rimmed, and the SW is cylindrical, the Quattro presents clean, straight four-sided lines with understated elegance. Cozy Heat describes it as stylish and elegant with clean lines and a minimalist design. Its distinguishing feature beyond the four-sided form is the large viewing window - notably larger than the glass doors on the other Cozy models - which makes the dancing flames the focal point of the sauna room from a wide viewing angle. The same 5mm stainless flame cutter, three-stage combustion, and German EN 15821:2010 certification apply identically across the entire Cozy Heat range.\u003c\/p\u003e\n\u003ch4\u003eFour-sided minimalist form and the large viewing window\u003c\/h4\u003e\n\u003cp\u003eThe Quattro body is four-sided with clean, straight lines - a geometry that reads as architecturally precise and modern in the sauna room. Where the three-sided Cozy models have an angular, dynamic quality and the cylindrical SW commands attention through its dramatic rounded form, the Quattro's square or rectangular profile is restrained and quiet - it sits in the sauna room as a functional object of considered minimalist design rather than a statement piece. The large viewing window is what elevates the Quattro above the merely functional: the generous glass panel lets the fire inside be viewed from a wide angle throughout the session, making the dancing flames an integral part of the sauna experience rather than a detail visible only when standing directly in front of the door. Cozy Heat uses the word \"mesmerizing\" to describe the glow of the flames seen through the Quattro's window - and the large format of that window is what justifies it.\u003c\/p\u003e\n\u003ch4\u003eUnderstated elegance - the minimalist Cozy\u003c\/h4\u003e\n\u003cp\u003eThe Quattro is for buyers who approach sauna design the way a Scandinavian architect approaches a building: functional clarity, clean geometry, nothing superfluous. The four-sided body has no curves, no rim elements, no cylindrical drama. Its surfaces are flat and its lines are straight. This is the design language of Nordic minimalism - the same aesthetic that produced the flat-white interiors, clear-finished pine walls, and bare wooden benches of the classic Finnish sauna. In that context, the Quattro is the most authentic expression of the sauna stove as a working object rather than a decorative element. The large glass window is the one concession to visual indulgence - and it is a practical one, since watching the fire is part of the wood-fired sauna ritual that no electric heater can offer.\u003c\/p\u003e\n\u003ch4\u003eComplete package - same proven Cozy Heat engineering\u003c\/h4\u003e\n\u003cp\u003eThe Quattro package includes the stove and sauna stones (style selected at checkout), with the correct stone load pre-specified for each output level: a minimum 265 lbs for the 12kW and a minimum 353 lbs for the 18kW. The flame cutter is 5mm stainless steel. The combustion system is three-stage - primary, secondary, and tertiary air - producing 25-40% less firewood consumption and 73.9% or 81.3% thermal efficiency at 12kW and 18kW respectively. A chimney installation is required and sold separately. All other installation requirements - dry seasoned hardwood, qualified chimney connection, no shared flue - are identical across the Cozy range.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eWood-burning sauna stove package with clean four-sided minimalist design - available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft), select at checkout.

Where the base Cozy, O, OG, SW, and Quattro all stand inside the sauna room with the firebox door facing the bathers, the Through-Wall stove is installed so that its firebox opening passes through the sauna wall - the stone mass and heat-radiating body sit inside the sauna room, while the firebox door faces the room or space outside the sauna wall. Wood is loaded from outside the sauna. The practical consequence is that wood loading, ash removal, and fire tending all happen without entering the sauna room, keeping the interior clean, smoke-free, and undisturbed during the session. This is the oldest and most traditional installation method for wood-fired saunas in Nordic and Baltic culture - the design that defined the Finnish smoke sauna and the Estonian heated chamber before modern stoves brought the firebox inside.\u003c\/p\u003e\n\u003ch4\u003eThrough-wall installation - what it means and why it matters\u003c\/h4\u003e\n\u003cp\u003eIn a conventional floor-standing sauna stove, the firebox door faces into the sauna room. To load wood, the bather or attendant must enter the sauna, open the door, load the logs, manage the fire, and remove ash - all from inside the hot room. In the Through-Wall installation, the stove body sits against the sauna wall with a purpose-built opening through the wall. The stone mass is inside the sauna where the heat and steam are needed. The firebox opening is on the other side of the wall - in the changing room, a utility corridor, or the outdoors. The person managing the fire never needs to enter the sauna room. Wood can be loaded while bathers are in session without interrupting them. Ash can be removed without entering the hot room. The sauna stays cleaner - no wood chips, bark, or ash on the floor, no smoke entering the room when the door is opened to load. For sauna buildings where the changing room or a utility space is adjacent to the sauna wall, the Through-Wall is a genuine operational upgrade over any conventional stove.\u003c\/p\u003e\n\u003ch4\u003eThe same Cozy Heat performance - different where it matters for installation\u003c\/h4\u003e\n\u003cp\u003eThe Through-Wall carries every technical specification of the Cozy Heat range. The flame cutter is 5mm stainless steel. The combustion system is three-stage: primary air through the grate, secondary air through the mid-chamber, and tertiary air through ceiling pipes that burn the flue gases as a third combustion stage. 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. The German BlmSchV DIN EN 13240 Level 2 and EN 15821:2010 certification apply. A chimney installation is required and sold separately. The installation itself is more involved than a conventional floor-standing stove: the wall opening must be correctly sized and fire-protected, the stove body must bridge the wall correctly, and the chimney must exit from the appropriate position. This work must be done by a qualified professional.\u003c\/p\u003e\n\u003ch4\u003e12kW or 18kW - and the sauna rooms the Through-Wall serves\u003c\/h4\u003e\n\u003cp\u003eThe 12kW Through-Wall 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, the same specifications as every other Cozy Heat model at these output levels. Cozy Heat describes the Through-Wall as \"perfect for intimate sauna rooms\" - which reflects the practical reality that the through-wall installation requires a wall shared between the sauna and an adjacent space, which is more commonly available in purpose-built sauna cabins and traditional sauna buildings than in converted interior rooms. The Through-Wall is the correct choice when the sauna building design allows or specifically calls for firebox-exterior installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eWood-burning sauna stove package with through-wall installation - firebox feeds from outside the sauna room.

The result is a complete wood-burning sauna stove package where the rounded, organic form of the O sits inside the sauna room with its stone mass visible within the circular rim, while its firebox passes through the sauna wall so that wood is loaded, fire is tended, and ash is removed entirely from outside the sauna. The sauna interior stays clean and undisturbed. The bathers stay in session without interruption. The stove body presents a soft, rounded silhouette in the sauna room rather than the angular lines of the standard Through-Wall. Available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft) with stone style selected at checkout, and complete with sauna stones included.\u003c\/p\u003e\n\u003ch4\u003eThe O design with through-wall installation - combining form and function\u003c\/h4\u003e\n\u003cp\u003eThe Cozy O Through-Wall is the only model in the Cozy range that offers both the circular rim design and external firebox loading in a single unit. The Cozy O (without through-wall) sits inside the sauna room and loads from inside. The Cozy Through-Wall (without the O design) passes through the wall with a conventional stove body form. The O Through-Wall combines them: the circular rim with its soft, rounded stone presentation faces the sauna interior, the firebox passes through the wall, and all fire management happens on the exterior side. For sauna room designs built around organic, rounded, or natural material aesthetics where the stove should appear as a soft rounded element within the space - and where the sauna building layout allows through-wall installation - the O Through-Wall is the specific model that serves both requirements simultaneously.\u003c\/p\u003e\n\u003ch4\u003eThrough-wall firebox loading - what it changes operationally\u003c\/h4\u003e\n\u003cp\u003eIn every Cozy model without through-wall installation, wood is loaded through a firebox door that faces into the sauna room. The bather or attendant must enter the hot room to tend the fire. In the O Through-Wall, the firebox opening is on the exterior side of the sauna wall - in the changing room, a utility corridor, or outside. Wood can be loaded while bathers are in session. Ash can be removed without entering the sauna. No wood chips, bark, or ash fall onto the sauna floor during loading. No smoke enters the room when the firebox door is opened. This is the traditional Nordic and Baltic installation method where the bathing chamber and the stoke-hole are intentionally separated - a design that treats the sauna interior as a clean, undisturbed space for bathing, and keeps all the operational work of fire management entirely outside it.\u003c\/p\u003e\n\u003ch4\u003eSame Cozy Heat engineering - circular rim, external loading, full performance\u003c\/h4\u003e\n\u003cp\u003eThe O Through-Wall carries every technical specification of the Cozy Heat range: 5mm stainless flame cutter, three-stage combustion system with primary, secondary, and tertiary air injection, 25-40% firewood reduction, and 73.9% or 81.3% thermal efficiency at 12kW and 18kW respectively. German BlmSchV DIN EN 13240 Level 2 and EN 15821:2010 certification apply. A chimney installation is required and sold separately. The wall penetration must be correctly sized and fire-protected, and the installation must be carried out by a qualified professional.

The sauna interior stays clean and the session undisturbed. Available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft) with stone style selected at checkout, complete with stones included. The OG Through-Wall is the specific model for buyers who want the most refined version of the trilateral three-sided Cozy form combined with the operational advantages of through-wall external firebox loading.\u003c\/p\u003e\n\u003ch4\u003eThe OG design with through-wall installation\u003c\/h4\u003e\n\u003cp\u003eThe Cozy OG body is the contemporary trilateral variant - three sides with clean lines and graceful curves that refine the base Cozy's more angular geometry into a more design-forward, polished form. In the OG Through-Wall, this body faces the sauna interior: the three-sided curved form with its stone mass is the visible element in the bathing room, while the firebox opening passes through the sauna wall to an adjacent space on the exterior side. Wood loading, fire management, and ash removal all happen outside the sauna without disturbing the session. For sauna rooms designed around a contemporary aesthetic where the stove body's refined trilateral curves should be visible from inside, and where the sauna building layout supports through-wall installation, the OG Through-Wall is the model that satisfies both requirements simultaneously.\u003c\/p\u003e\n\u003ch4\u003eThrough-wall operation - clean sauna, undisturbed session\u003c\/h4\u003e\n\u003cp\u003eIn all conventional inside-loading Cozy models, fire management requires entering the hot sauna room. In the OG Through-Wall, the firebox door is on the exterior side of the sauna wall - in the changing room, a utility corridor, or outdoors. Wood is loaded from outside. The fire is tended from outside. Ash is removed from outside. No wood chips, bark, or ash on the sauna floor. No smoke entering the room when the firebox door opens. The session continues without interruption. This is the traditional Nordic and Baltic installation method that kept the bathing chamber as a clean, uninterrupted space for bathing and separated all the operational work of fire management to a dedicated exterior space. The OG Through-Wall brings this traditional functional principle together with Cozy Heat's most refined trilateral design form.\u003c\/p\u003e\n\u003ch4\u003eSame Cozy Heat engineering throughout\u003c\/h4\u003e\n\u003cp\u003eEvery technical specification of the Cozy Heat range applies: 5mm stainless steel flame cutter, three-stage combustion (primary air through the grate, secondary through mid-chamber channels, tertiary through ceiling pipes burning the flue gases as a third combustion stage), 25-40% firewood reduction, 73.9% efficiency at 12kW and 81.3% at 18kW, and German BlmSchV DIN EN 13240 Level 2 and EN 15821:2010 certification.

The session stays undisturbed. The interior stays clean. Available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft) with stone style selected at checkout, complete with stones included. The SW Through-Wall is the specific model for buyers who want the most visually dramatic form in the Cozy range - the cylindrical pillar - combined with the operational discipline of through-wall external firebox loading.\u003c\/p\u003e\n\u003ch4\u003eThe SW cylindrical design with through-wall installation - drama inside, clean operation outside\u003c\/h4\u003e\n\u003cp\u003eThe Cozy SW body is the most dramatic in the Cozy range: a sleek cylindrical column with smooth continuous curves and no angles or flat faces. In the SW Through-Wall, this cylindrical form stands inside the sauna room as a sculptural element - a pillar of radiant heat rising from the floor to the stone mass above, visible and commanding from every position in the room. The firebox that feeds it passes through the sauna wall; wood is loaded and the fire is managed from the adjacent exterior space without disturbing the bathers inside. This is a notable combination: a stove designed for visual impact inside the sauna, paired with an installation method that keeps all the operational work outside it. The cylindrical column commands the room; the fire behind the wall keeps it running. The sauna stays clean and the session stays uninterrupted.\u003c\/p\u003e\n\u003ch4\u003eThrough-wall operation - what it changes\u003c\/h4\u003e\n\u003cp\u003eIn the Cozy SW PKG (inside-loading version), wood is loaded through a firebox door that faces into the sauna room - the bather or attendant must enter the hot room to manage the fire. In the SW Through-Wall, the firebox opening is on the exterior side of the sauna wall, in the changing room, a utility corridor, or outdoors. Wood can be loaded while bathers are in session. Ash can be removed without entering the sauna. No wood chips, bark, or ash on the sauna floor around the base of the cylinder. No smoke entering the room when the firebox door opens. The traditional Nordic and Baltic sauna design principle - bathing chamber clean and separate from the stoke-hole - applied to the most contemporary stove form in the Cozy range. The exterior of the sauna building must have an accessible adjacent space on the firebox side of the wall, and the wall penetration must be installed by a qualified professional before the stove can be used.\u003c\/p\u003e\n\u003ch4\u003eSame Cozy Heat engineering - 5mm stainless flame cutter throughout\u003c\/h4\u003e\n\u003cp\u003eEvery technical specification of the Cozy Heat range applies to the SW Through-Wall without modification: 5mm stainless steel flame cutter, three-stage combustion with primary, secondary, and tertiary air injection burning the flue gases as a third combustion stage, 25-40% firewood reduction compared to comparable stoves, 73.9% efficiency at 12kW and 81.3% at 18kW, and German BlmSchV DIN EN 13240 Level 2 and EN 15821:2010 certification. A chimney installation is required and sold separately.

Available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft) with stone style selected at checkout, complete with stones included. The Quattro Through-Wall is the specific model for buyers who want the understated elegance and fire-watching qualities of the Quattro combined with the operational cleanliness of through-wall external firebox loading - and it produces a particularly compelling combination: the large window frames the dancing flames for bathers inside, while all the fire management happens invisibly on the other side of the wall.\u003c\/p\u003e\n\u003ch4\u003eThe Quattro's large window and through-wall operation - a natural pairing\u003c\/h4\u003e\n\u003cp\u003eThe Cozy Quattro is defined by two things: its four-sided minimalist body with clean straight lines, and its large viewing window - notably larger than the glass doors on other Cozy models - which makes the dancing flames the focal point of the sauna room from a wide viewing angle. In the Quattro Through-Wall, this large window takes on additional significance. In a conventional inside-loading stove, the firebox door is opened regularly for wood loading and fire management - each opening briefly reveals the firebox mechanics and introduces some disruption to the sauna atmosphere. In the Quattro Through-Wall, the firebox is on the other side of the wall. The large window faces the bathers throughout the entire session, showing only the fire itself, never the mechanics of loading or ash removal. The flames are always visible and always uninterrupted. The large window of the Quattro, combined with through-wall operation, produces a cleaner fire-watching experience than any inside-loading stove can offer.\u003c\/p\u003e\n\u003ch4\u003eThrough-wall operation - clean interior, undisturbed session\u003c\/h4\u003e\n\u003cp\u003eIn the Cozy Quattro PKG (inside-loading), wood is loaded through the firebox door that faces into the sauna room. The bather or attendant must enter the hot room and open the door to tend the fire. In the Quattro Through-Wall, the firebox door is on the exterior side of the sauna wall - in the changing room, a utility corridor, or outdoors. Wood is loaded from outside. Ash is removed from outside. No wood chips, bark, or ash on the sauna floor. No smoke entering the room when the firebox door opens. The session continues uninterrupted. The Quattro's large window faces the bathers throughout, showing only the clean view of the fire burning within the four-sided enclosure. This is the most fully realised expression of the Quattro's design intent: the fire as a visual feature of the sauna, not an operational task performed within it.\u003c\/p\u003e\n\u003ch4\u003eSame Cozy Heat engineering - 5mm stainless flame cutter throughout\u003c\/h4\u003e\n\u003cp\u003eEvery technical specification of the Cozy Heat range applies: 5mm stainless steel flame cutter, three-stage combustion with primary, secondary, and tertiary air injection burning the flue gases as a third combustion stage, 25-40% firewood reduction, 73.9% efficiency at 12kW and 81.3% at 18kW, and German BlmSchV DIN EN 13240 Level 2 and EN 15821:2010 certification.
