Harvia M Series Wood Stove Sauna Heater with Exterior Feed

The Harvia M Series Wood Stove Sauna Heater with Exterior Feed features a glass door that allows the glowing fire to create a cozy fireplace feel. This unique design allows for the stove to be heated from outside the sauna, creating a relaxing ambiance while your sauna heats up on the other side of the wall. Enjoy the steam moments in the comfort of the fireplace room setting.

The Harvia M3 SL stove provides strong steam for small home saunas. Its stone compartment ensures efficient steam and a quick heat-up time. With adjustable legs, installation is made easier - the smoke outlet can be easily positioned at the proper height. An optional chimney-mounted water heater is available for the stove. The exterior of the stove is constructed with stainless steel.

 

Harvia M Series Wood Stove Sauna Heater with Exterior Feed offers versatile bench options and the possibility for water heating with a separate tank placed on the chimney. This allows for a longer fireplace without the need to install it through the wall, providing a more convenient loading experience for some of our clients.

Comfortable, warm enough. Feels a bit like a shawl but looks like a good sweater.
I like the color and the fit is good, roomy, feels a bit like a shawl but holds shape and hides a few extra pounds. The zipper is thin but whether you'll find it good enough to last I wouldn't know yet. I'm keeping this.

Comfortable, well put together, nice material, size chart is way off.
Color: Black, Size: 3X-Large
A well put together sweater that is made with very soft yarn, and doesn't seem to have any major structural issues. The zipper works great and the stitching looks like there's not major flaws. The only big issue is the 3XL sweater I got is way off size wise. Oversized sweaters are great, so I was excited about getting this for me to use for day to day wear, and my wife (who is a lot smaller than me) to steal when she's watching tv on the couch or sitting outside, so the disappointment was palatable. Sadly the 3XL size is about the same size as XL sweaters in the closet, where as a few 2xl sweaters we recently ordered from another company are a lot larger than this one. Outside of the major size discrepancy, which could be a major deal breaker for some, the sweater itself is really comfy and really nice. Sadly 3XL is the largest size we could get on the chart.
