HUUM Hive Flow Mini LS: a small wood sauna stove fed through the wall

The HUUM Hive Flow Mini LS is the compact Hive Flow Mini wood burning sauna stove with a firebox extension, so the fire door sits in the sauna wall and you add logs from the next room. It stands on the floor and is rated at 8.5 kW for rooms from 212 to 494 cubic feet. Its furnace puts about 75 percent of the wood’s heat into the sauna instead of up the chimney. With the extension, it measures about 18 inches wide, 26.5 inches deep, and 35 inches tall. It weighs 130 pounds, burns logs up to 12 inches long, and holds 231 pounds of stones. The flue can exit from the top or the back.

You get the stove, a metal grate, an ash grate and ash drawer, two cleaning hatches, two fixing plates, splints, a heat resistant glove, and the manual. Sauna stones are sold separately, so add the 7 boxes it needs on the page. A chimney is not included, so pick the through the ceiling, through the wall, or barrel sauna chimney kit on the page. A mounting collar for the wall opening, a floor plate, protective bedding, and a stone cage are optional. Loading from inside the sauna? The plain HUUM Hive Flow Mini stove is a few inches shorter. The HUUM Hive Flow Mini LS ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ

What makes the Flow Mini LS efficient?

Per the description, its innovative design sends 75 percent of the heat from the firewood directly into the sauna instead of up the chimney, with a patent-pending furnace construction, economical wood use, and a mild, long-lasting steam – the signature of the series.

What size sauna does it heat?

Rooms from 212 to 494 cubic feet, with a minimum room height of 75 inches per the specification table. If you are weighing wood-fired sizes, the HIVE Flow line also includes a 9.8kW model for larger rooms.

What is the firebox extension for?

This LS version ships with the firebox extension listed in its features and title, extending the firebox front deeper than the standard Mini – its overall depth is 26.5 inches versus the standard model’s 21.1. Consult the installation manual for how the extension is configured in your build.

Do I need to buy a chimney separately?

The stove needs a flue – connections are on the top and back per the specification table – and matching HUUM chimney kits for thru-ceiling, thru-wall, and barrel sauna installs are right on this page under Operating Accessories, so order the venting with the stove.

How long can the firewood be?

Up to 12 inches (300 mm), per the specification table – shorter than the full-size Flow, so plan your wood supply around it. The stove ships with splints, grates, cleaning hatches, an ash drawer, and a heat-resistant glove for tending the fire.

What are the required stones?

It has a 231-pound stone capacity listed as seven boxes of HUUM Stones 24 small (5-10 cm) stones. The description says they are sold separately, and the Required Stones add-on on this page is where to add them to the same order.

What clearances does it need?

The specification table lists safety distances of 52.5 inches front to back and 30 inches left to right. The Sauna Room Safety add-ons on this page – mounting collar, protective floor plate, and protective bedding – support a compliant setup; follow the manual throughout.
