    Placement in the room, following the manufacturer's specification.

  • Delivery and placement

    Freight coordination to your site, and the stove placed in the room it heats.

  • Assembly

    Installed as part of the sauna build, with the stones loaded.

  • Protection

    Guards and clearances set at install and checked when we come back.

  • Support after the build

About this buildout.

All four are front fed inside the sauna and stand on the floor. The Linear 16 Black has a cast iron door with glass whose opening direction can be changed, and holds up to 80 lbs of stones. The Linear 18 Compact Black has a double steel shell that keeps the outer surfaces cooler, a glass hatch, and an ash box that sets the air flow.

The Linear 22 GreenFlame has a large glass door and the maker's GreenFlame fire chamber, rated at 20 percent lower particulate emissions and 70 percent lower carbon monoxide emissions. The Linear 22 GreenFlame ES is the same stove with a 20 liter water tank built in and a spout low on the stove.

The 18 Compact and both Linear 22 stoves hold 88 lbs (40 kg) of stones and share a 17.7" width; the ES is deeper to carry the tank.
