Product Benefits

The Cozy Heat Quattro is a wood burning sauna stove with a square cage built from horizontal steel bars. Straight sides mean no wasted space at the corners, so it holds 265 lb of stone on the COZYQUATTRO12 in a body only 17.3 in wide. That is the same rock as the wider OG and SW in a narrower footprint. The COZYQUATTRO12 heats a home sauna room of 210 to 423 cu ft and the COZYQUATTRO18 covers 317 to 635 cu ft. Both are wood burning sauna heaters that install on the floor with no power and no wiring, and the only routine jobs are emptying the ash box and restacking the stones once per year. Stones and chimney are used with the stove and both are sold separately.

Round cages waste the corners. Square cages do not. The Quattro carries 265 lb of stone on the 12 kW, the same as the OG and the SW, in a body 2.3 in narrower than the OG and 2.0 in narrower than the SW. In a room where the bench gap decides what you can fit, that is the whole argument.

Cozy 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. That is European certification. They do not carry a UL, ETL or CSA listing. 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. Check with your local building department and your insurer before you order. Lead time is 60 days from Estonia and these ship by LTL freight, so a permit problem found after delivery is an expensive one. If your inspector requires a listed stove, call us before you order and we will tell you which of the wood burning stoves we carry hold a listing for your area.

You can find a cheaper wood sauna stove. You cannot buy this one cheaper: Cozy Heat sets the price and every dealer holds it. What changes is what comes with the order.

The specs back that up. The COZYQUATTRO18 runs at 81.3% overall efficiency with a flue gas temperature of 234 °C / 453 °F. The COZYQUATTRO12 runs at 73.9%. Dust emission is 22 mg/m³ and 35 mg/m³. Both burn wood logs only, up to 30 cm / 11.8 in on both. Both are black steel with a 114 mm / 4.49 in flue that exits from the top.

The Quattro is the second narrowest stove in the range at 17.3 in on the 12 kW, behind only the base Cozy Heat at 16.9 in. It is also the shortest 18 kW at 28.7 in. Clearances are the same across the range: 6.7 in to the sides on the 12 kW, 9.1 in on the 18 kW, 9.1 in behind and 19.7 in in front. Allow 44.5 in above the COZYQUATTRO12 and 52.8 in above the COZYQUATTRO18. Maintenance is the ash box after each session and a restack of the stones every 12 months.
