We stumbled into the Tiny Wood Stove business after trying to source a stove for our Tiny Home a 1966 Airstream. We wanted a modest sized wood burner for affordable off-grid dry heat. After scouring the internet to find every possible solution we compiled a list of all the options. What we found was a bunch of stoves that were not ideal for our situation. They weren’t the right size, they didn’t have the right features or they were beyond our budget. So we set out to create the perfect stove for small spaces. The Dwarf is efficient, durable and affordable!

The sturdy body is made of thick 3/16″ – 5/16th Steel Plate.



The door is made of high-quality cast iron with a large fire viewing window for a classy look while providing optimal heat retention.



The 4” flue outlet can exit out the top or the rear of the stove depending on your needs. Exiting out the rear of the stove allows the entire top surface to be used as a cooking surface while exiting out the top of the stove allows are tighter installation with less clearances.



The Dwarf gives you complete control over primary, secondary and tertiary air supplies. The airtight primary and secondary air are controlled by separate levers on the bottom of the stove and the tertiary air-wash is controlled by a slide valve just above the door.



The Dwarf firebox is made of durable cast iron and fire brick. Cast iron is very durable with for continuous use, and the fire bricks keep reflect heat back into the firebox for a more efficient burn.




The bottom of the firebox is a cast iron grate with a mechanical lever (located lower left of door) that engages the floor of the grate sifting out ash from the firebox. This handy feature is a must for coal, and helps to quickly and efficiently clean out the firebox. Below the grate is a removable ash pan for easy disposal.



You can customize the look of your stove by adding the tall cast iron legs or wood storage stand.  Limited numbers of enamel doors are available as a special order item (contact us if you’d like one).  Future accessories include a water boiler option and factory heat shields.



400mm/16” sides, 450mm/18” rear. You can reduce required clearances by up to 2/3 with a properly designed heat shield.



The Dwarf can safely burn wood, coal or compressed logs.

    We LOVE our dwarf 4kw tiny wood stove. We’re really happy with the build quality, design and performance and it’s hands down our FAVORITE part of our bus.

    We installed it in our 31 ft. converted prison bus tiny home about eight months ago. After traveling early this year, we spent two months in northern New Hampshire winter temperatures. The 4kw kept us very warm & comfortable. We actually really enjoyed using and tending to it.

    Installation of our stove was simple and straightforward; everything you need is provided in their install kit.

    We went with an enameled door and LOVE it.

    Purchased a Dwarf 4K to replace an existing wood-coal stove aboard our 50′ sailboat. I wanted to install the 5K version but it required different sized venting and deck hardware which would have added to the installation cost.
    After some hemming and hawing typical of boaters, I decided on the Dwarf 4K. While we only used the original wood-coal stove as supplemental heat to our primary diesel heating system, the Dwarf 4K has actually become our primary heating source as it keeps the complete boat warm, dry and comfortable in temperatures down to 25F.
    Below 25F the stove requires more close supervision and stoking throughout the night, but could keep the boat warm down to an outside temp of 20F dependent on firewood type. Hardwood seems to be the best wood for the longest burn but requires more labor to get it to a functional size. The smaller compressed wood byproduct bricks work well but are tricky to adjust for a slower burn, having a tendency to burn quicker than firewood. We keep a MAP torch handy for lighting the kindling and preheating the flue in order to get a non-smokey startup.
    Overall we’re happy with the Dwarf. I’d offer a few extras for boat owners like a hot water coil and a pot rail common on boat installations. There are smaller products on the market but the Dwarf 4K just the right size to have a lasting burn time to make it through the night which makes it a good choice for boaters.

    The stove is working great. It was installed in a 12′ x 16′ cabin with walls and ceiling insulated with R-13, no insulation in floor, which is elevated about 16″ off of ground. Stove produces enough heat to be uncomfortable when run hot but is good when dampened down heavily and almost lasts through night.

    Customer service was best I’ve ever experienced. I regularly had Tiny Wood Stove contacting me to make sure everything was going well. I was able to return products with no issues and was allowed plenty of time to do so. I’m very pleased with my experience with TWS, thanks a ton!

    The stove is the perfect size for my application. I’ve been building a super insulated ~450ft.^2 home in remote Alaska’s sub-arctic. This winter the temperatures were -50F at my door. I use an oil stove to maintain heat when I’m gone and the wood stove works great when I’m there. I’ve found the controls to quite good, and the wood that I’ve used thus far has been burned quite efficiently. Again, for my super insulated small cabin…this stove works great. House specs: ~ 450ft.^2; R-45 Wall, R70-Roof/ceiling, R-40 floor. Also their customer service was quite good.

    Stove has been up and running for a few months now. The quality of all the parts and stove itself are excellent. Should last for many, many years to come. Thanks for all the help to get this up and running. I write this as I sip coffee in front of our little stove, on this frosty morning in Pennsylvania. The only thing I added was a spring handle to make the handle more user friendly. I use this as a primary heat source on our 750 sq foot home, and it does a great job heating the house. We have electric heat, however with this stove now installed we are saving approximately $200 a month on our electric bill during winter. The setup will pay for itself in no time.

    High quality stove works very well in my 27′ travel trailer. Surprising heat output from a small device.

    The calculator says I could have used a 3kW stove but I am glad I chose the 4kW. Don’t be a cheap skate with the installation. Get the kit and do it right.

    My stove sits on the floor so I am definitely glad I got the taller legs. Great stove, great customer support. Highly recommended.
