M3 Reviews

We also purchased the Harvia M3 with a stainless steel chimney kit. While my husband and I are both pretty good mechanically, for the life of us can’t get the stovepipe put together correctly. The instructions weren’t included and what Harvia has online is pretty meager at best. The sauna manufacturer, sadly, also needs a bit of a clean-up on their instructions.

We have a simple barrel sauna with a Harvia M3 stove. We are happy with everything about it…except…the flimsy wire hinge on the stove door. It is literally a thin piece of wire. Eventually the door is going to fall off and the glass will break.

We recently constructed our barrel sauna from Dundalk. We also purchased the Harvia M3 with a stainless steel chimney kit. While my husband and I are both pretty good mechanically, for the life of us can’t get the stovepipe put together correctly.

Where can I find the manual?

Can the Harvia M3 be connected to a masonry chimney?

Yes, the M3 has rear and upper connection options, and can be tied into an existing masonry chimney in good condition. You will likely want and need a chimney liner if you don't already have one - consult your local building department.

Can you install this on a wood floor?

Yes, but the Harvia Protective Bedding must be used.

Can it be connected to a masonry chimney?

Make an opening in the fireproof wall for the flue connection. Notice that the opening has to be at the correct height, if you intend to use, for instance, a protective bedding. The hole should be slightly larger than the flue connecting pipe. A suitable gap around the connection pipe is ca. 10 mm. It is advisable to round off the inner corners of the flue opening to ensure that the combustion gases can flow freely to the flue.

Refer to manual for instructions on connecting to top of M3 to chimney.

Can it be installed on an uneven floor?

The adjustable legs enable the stove to be installed firmly on an inclined floor. The adjustable range is 0–30 mm. Unscrew the adjustable feet to an extent that allows them to be adjusted using a wrench (17 mm) when the stove is in position.

Do I need to preburn outside the sauna first?

Yes, as with all wood burning sauna stoves you should set it up outside on a calm day and 'preburn' to cure the paint until you can't smell any odors. Timing will depend on how hot you get it, but we like to get a good burn going for 4 hours before installing. Be sure to let the stove cool off before installation, preferably overnight.

Does it need a vent? Where?

Yes, all wood stoves require ventilation for proper combustion. Harvia recommends an intake vent behind stove, very low on the wall and a exhaust vent high on the opposite wall.

Who's it for?

The M3 is perfect for any small, wood-burning sauna that wants a mountable stove. This makes it a great candidate for mobile saunas, or saunas with slanted floors. It has the lowest clearance of any Harvia wood burning stove, so it's perfect for saunas where space is at a premium.

Our Harvia M3 Review

If you’re looking for a wood-burning sauna stove with a classic look and modern elements, look no further. It’s popular in mobile saunas and barrel saunas, and it’s very easy to find the Harvia M3 for sale in most countries.

You can see it in action, or even try it out on SaunaShare.com where it’s one of the most popular sauna stoves for small public saunas and mobile sauna trailers.

In addition to mobile saunas, the Harvia M3 is suitable for small to medium indoor saunas that have a suitable to send the chimney up through the roof, outdoor barrel saunas, and outdoor shed style saunas.

It’s inexpensive but doesn’t look or feel like a cheap heater.

It’s our understanding that the Harvia M3 is still designed and manufactured in Finland, using high quality materials.

Note that if you are not cutting your own wood you will have to get it cut to a certain size, which can be expensive or impossible. The maximum logs that fit in the M3 are 6″ diameter and 13 3/4″ long.

If that’s an issue, use the Sauna Marketplace stove finder to dial in a heater that works best for you. Find our full ranking of the best wood burning sauna stoves here.
