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 which gives the face of the stove a classy look while providing optimal heat retention. (Cast iron remains hot much longer than steel)



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. Primary and secondary air are controlled by a single slide lever at the bottom of the stove and the tertiary air wash is controlled by a small gate valve just above the door.



The firebox of the Dwarf is made of durable cast iron and fire brick. Cast iron is very durable with constant heat use and the fire bricks keep the fire very hot which helps combust the wood thoroughly.




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 super handy for quickly and efficiently cleaning out the firebox. Below the grate is a removable ash pan that catches ash for easy disposal.



You can customize the look of your stove by adding the tall cast iron legs or wood storage stand. We are working on additional off-grid features like: cooktop and water heater.



400mm/16” sides, 450mm/18” rear. Clearances can be reduced by up to 2/3 with a properly designed heat shield.



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


NOTE: This stove is not intended for residential heating. It is currently uncertified and only offered for recreational use.

    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!
