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.
Note: requires a minimum of 66 lbs of stones (2 boxes) sold separately.

THE HEART OF THE SAUNA
Be it an electric or a wood-burning heater, steamy or dry, one thing is for sure; it heals you. Harvia’s heaters are your traditional source for modern well-being. From the beginning, Harvia’s heaters have been forged with quality as a priority. With over 70 years of craftsmanship, Harvia heaters are reliably built to last. Easy to use, practical, and safe – you are sure to find a fitting heater for your sauna.
Your Sauna's Powerhouse
The right heater is the heart and part of the interior and atmosphere of the sauna. From our selection, you can find the right electric heater and design for your needs. You can also choose the heater based on your steam preferences. A large stone capacity in pillar heaters provides soft steam. If you like dry and hot steam, then a smaller stone amount in our wall-mounted heater is perfect for you. Harvia's product range offers solutions for both home and commercial use.
The power of the electric heater is based on the size of the sauna and the interior materials used in the sauna. An average of 1 kW of heater power is required per cubic meter of sauna volume. The need for power increases if the sauna has window or glass surfaces or heat-storing surfaces, such as brick or concrete.
Enjoyment to all Your Senses
In the wood-heated sauna, you will enjoy the sauna culture in its most authentic way. The atmospheric light of the blazing flame, the scent of wood, and the pleasant hum from burning wood relax your mind and take you away from the everyday rush.
With decades of experience, we offer the best and safe wood burning heater solutions for saunas of any size. Our wide selection includes wood-burning heaters, water heaters, safety equipment, and chimneys – not to forget, ready-made sauna solutions from benches to complete saunas.
Combine both the Heat and Steam
Do you love steam and enjoy the heat but don't know whether you should choose a steam generator or an electric heater? Then Combi heaters are perfect for you. As the name says Combi heaters are a combination of an electric heater and a built-in steam generator.
You can adjust the humidity and temperature separately as the heater and the steamer have their own heating elements. It is possible to determine the humidity of the sauna with an accuracy of one percent.
Take Control of Your Sauna
Separate control units are suitable for our E-model heaters. You can operate them with the control panel, which, depending on the control unit, is separately installed or on the control unit itself.
You can also install other sauna devices such as lighting, ventilation, steam generator, or combi heater to the control unit, and then they can be operated from the control panel as well as the heater. Every part is easy to maintain once they have been installed.
Control panels are used to control the functions of the installed devices. Electric heaters that don't require separate control units have the necessary capabilities built into the heater, such as our XE-model heaters. Our control panels can be surface mounted or embedded into the wall, and they can be installed inside or outside the sauna room.

Engineered great EXCEPT for the fact that the chimney connection should fit inside of the pipe not over it. Could be a potential problem at some point. The stove itself is nice and works well.
I’ve used the sauna quite a few times. I put a digital thermometer in there. And the temp reads about 138. Not 150 like the sauna thermometer says. That’s a little disappointing
Good looking compared to others, works well. Easy to install. The instructions could definitely use improvement.
On the expensive side, but there aren't many options.
I recommend a hearth pad underneath the heater and not placed directly on a combustible surface.
I’m a 5’10 260 pound former competitive bodybuilder and fit great in the sauna. After a month or so of use I have to say Im impressed.
Incredibly happy with the sauna. High quality, easy build, great support from the company
Thank you, Brandon! Hope you enjoy your Salem barrel sauna!
I tried the Harvia M3 woodstove only once -- It seems like a good woodstove -- the sheet metal on the outside buckled a little bit after starting the first fire but did not impact the performance -- when I get the sauna built I will give an update
So far, I’ve received my gas heaters, but no saunas yet to try and review something that’s sitting on the shop on my floor and I haven’t used would be kind of silly. I’ll let you know when I receive my saunas and so I can install them.
Everything was easy: the initial interaction, the order, the shipping and the assembly. It is a very attractive little unit and works great.
Just completed the sauna build and the stove is great; it heats up the 7x7 room quickly. Very appealing design visually and was easy to install. I like the nice size window to watch the fire while sweating away. Delivery to my rural location was easy and well communicated. Definitely happy with the purchase!
I have tried and tried and it gives me error 7,1,0 and I cannot control de sauna via WiFi on the app…
Sorry guys. I love the sauna. But this is NOT the right heater for this sauna. The controls are inaccessible while the heater is on. I’ve been working with the manufacturer on a replacement.
Steve, really sorry to hear you didn't enjoy the KIP 6kW with your SaunaLife 3-Person Cube. This heater is the recommended standard for this sauna so we will definitely share your feedback with the manufacturer. Glad you love the Sauna though, we appreciate you working with us! We would be happy to assist you further if needed, you can reach us anytime at 1-877-587-5387.
Best online shopping experience yet. Can’t say enough how pleased I am with my purchase and glad I chose Nordica Sauna. I ordered the Auroom Mira L with all the accessories to complete the project. Eric was extremely helpful and patient while answering all of my questions and even reached out to the manufacturer to confirm on a couple of them. Eric and Maja continued to check in after the delivery, during assembly and even after the final assembly to make sure things were good. Highly recommend.
We had a very good experience with Nordica Sauna sales person Eric. Over a period of several months I called him many times to make sure I understood what I was getting to help me figure out what the best sauna for us, and to assure me that if there was a problem he would help us. There was no problem. Everything went perfectly. We are very happy we give Erica 10 and we give the Sauna Finnmark hybrid F-D 4 a 10 as well we could not be happier. We were so worried we would buy the wrong one and now we know that we chose the correct sauna for us. We wanted to Sauna to get really hot and this one does the job. The wood is super good quality smells so good and brand new! Everything works correctly.
It was delivered on time, and it wasn’t too difficult to put together. I do recommend however getting the wires through the top before you try to put it on set it on a box and then take the top panel off and then stick the wires to their appropriate holes so when you put it on the top, you can connect them properly to the ones coming out of the sauna box makes it easier this way when you put it on. Anyhow please send a note if you’d like advice.
Thank you Eric for helping us purchase this most wonderful health benefit. And I would say that the Sauna kills inflammation, and anything growing in you.
This Sauna would help anyone suffering from health problems. I lost 15 pounds in two months without even trying. I wasn’t even dieting I think I lost inflammation. I feel better and healthier since starting using it. We love our Sauna.
I was a little unnerved when the shippers placed a very heavy crate in my driveway during a thunderstorm and drove away. I called Nordic and they told me that although they could not take responsibility for the shippers' behavior, they would take responsibility if there was any damage. I released the straps holding the boxes together and found that everything was very well packed and easy to manage peice by peice with a helper. Assembly was extremely easy! I took one look at the intructions and the order pieces were put together and the rest was obvious. The whole unit was assembled in an hour and when I turned it on, it worked perfectly! I was impressed with the sound from the speakers when I connected my smartphone to the system. All in all, I'm very happy and recommend this company and this product with confidence.
I recently received the body brush, the
Laddle and the beautiful timer. All very good quality! The package has been delivered on time and Maja informed beforehand via text messages that the order is on its way. As usual very good services and great communication. Thanks!
It is as beautiful as the picture high-quality and just so nice. We have gotten so many compliments.
Eric was our rep ordering this item and they worked perfect! Eric was great handling our order.
Still in the box. Building next week!
Yes, I am delighted with my Nordica sauna and find it comfortable and efficient. I only wish I could increase the temperature so I could bring up a sweat.
Golden Designs Maxxus 4-Person FAR Infrared Sauna - Low EMF | MX-K406-01
Received the pallet and all looked okay, except 2 boards were extremely bowed which shortened the length just enough so they do not fit into each side of the grooves. The barrel remains unfinished because I cant place them into a V because it's absurd the amount of warping wont let them meet and sit into the grooves. Smells great.
Bought this on a whim, best spontaneous decision ever made. My boyfriend and I love ending our day with a workout and sauna session. Our sleeping has improved and our overall mood has improved.
