RecovAthlete\ncarries eleven of them: five standard models that you load from inside the sauna,\nfive thru-wall models that you load from the room next door, and one outdoor fire\npit. Each stove comes in a 12 kW and an 18 kW version. The 12 kW heats a room of\n210 to 423 cubic feet. The 18 kW heats 317 to 635 cubic feet.\u003c\/p\u003e\n\n\u003cp\u003eThe design point is stone mass. A Cozy Heat holds 243 to 397 pounds of stone\ndepending on the model, which is a lot for a stove this size. Stone stores heat and\ngives it back slowly, so the steam stays even through a long session instead of\nspiking and fading.

Firewood is 8 to 12 cm across. Maximum log length is 13\ninches on the 12 kW and 15.7 inches on the 18 kW. Side clearance to a combustible\nwall is 6.7 inches on the 12 kW and 9.1 inches on the 18 kW, with 19.7 inches at the\nfront on both. A shared flue is not permitted.\u003c\/p\u003e\n\n\u003cp\u003eThe stoves are tested to EN 15821:2010 and BImSchV DIN EN 13240 level 2, which\nare European construction and emissions standards. \u003cstrong\u003eThey carry no UL, ETL or\nCSA listing.\u003c\/strong\u003e If your local code, your inspector or your insurer requires a\nNorth American safety listing, these stoves will not satisfy it.

That is what the outer cage buys you. The Cozy Heat is a wood burning sauna stove from Estonia, and the firebox sits inside an angular cage of diamond expanded steel mesh, packed with stones on every side. Heat leaves through rock rather than bare steel, so the room warms evenly and holds. The only routine jobs are emptying the ash box and restacking the stones once per year. It comes in two sizes: the COZY12 for home sauna rooms of 210 to 423 cu ft, and the COZY18 for 317 to 635 cu ft. Both are \u003ca href=\"\/collections\/wood-burning-sauna-heaters\"\u003ewood burning sauna heaters\u003c\/a\u003e that install on the floor with no power and no wiring.

The heat spikes and drops, and the löyly is weak because there is not enough hot rock to make it. Cozy Heat builds it the other way round: 243 lb of stone on the COZY12 and 353 lb on the COZY18, wrapped around the body rather than stacked above it.\u003c\/p\u003e\n\n\u003cdiv class=\"rca-warn\"\u003e\n\u003ch4 class=\"rca-label\"\u003eIMPORTANT: NO UL, ETL OR CSA LISTING\u003c\/h4\u003e\n\u003cp style=\"margin:0;\"\u003eCozy Heat stoves are CE marked under the Construction Products Regulation 305\/2011 EU, tested to EN 15821:2010 and BImSchV DIN EN 13240 level 2 by TUV SUD Industrie Service GmbH, notified body 0036, with a reaction to fire class of A1.

Many US and Canadian jurisdictions require a listed solid fuel appliance before an inspector will sign off, and some home insurers ask for the same.

This one trades some of the flame for stone, and what you get back is heat that reaches further and stays longer once the wood burns down. That is worth more on a cold evening than a bigger flame.\u003c\/p\u003e\n\n\u003cp\u003eWant the stone capacity confirmed before you order rock, or the freight cost to your address?
