Description

The Harvia M3 BK PKG is a wood-burning sauna stove package built around the Harvia M3 heater, delivering 16.5 kW of heat output for sauna rooms sized 212–459 ft³. Finished in black and designed for floor installation, this kit bundles the core components needed to set up a traditional wood-fired sauna heat source with matched protective and chimney parts.

At the center of the package is the Harvia M3 wood-burning heater, built with a steel body and specified for interior wet-area sauna environments. The heater includes a glass door to bring firelight into the sauna room, and it features a stainless steel air-flow spoiler to support efficient air circulation while you heat. The stone compartment is sized for a 66.2 lbs stone load, and the package includes the matching sauna stones in a split-face form factor with olivine diabase stone material and a stated 4–6 in stone size range.

To support safer installation and protect surrounding surfaces, the package includes both protective bedding and a protective sheath. The protective bedding is made from black aluminum-zinc coated steel and is designed to help protect floors beneath the heater. It includes adjustable feet and can be installed on a sloping floor, helping you fine-tune leveling where needed. The included protective sheath is a 3-sided black steel surround intended to reduce safety distance to combustible materials, offering an added layer of protection around the heater body.

For venting, the package includes a matched chimney kit plus a chimney extension. The chimney kit is specified as black powder-coated steel with mineral wool insulation material, designed to mount in a vertical position, and described as soot fire resistant and freeze thaw resistant. The kit is also stated to be able to be easily extended, and this package includes the matching extension section to increase overall chimney height as required by your installation plan. Included chimney accessories and pass-through components are part of the package contents, supporting a more complete, coordinated setup from heater to venting.

Harvia’s approach centers on sauna-focused engineering, pairing heater design details with practical installation components intended for real-world sauna builds. With Finnish roots and long-running experience across sauna products, the brand’s focus is on delivering dependable heating solutions that fit a wide range of traditional sauna configurations—especially for owners who want the feel and ritual of wood-fired heat in a compact-to-midsize sauna room.
