Our warehouse team works hard to get your order shipped to you as quickly as possible in the order it was received. If you have any special requests, you can always add them to the order comments or email us at email@example.com.
Because we're a small company, processing times for in-stock items can vary between 0 and 7 days from the date you placed your order, depending on how busy we are. Items that require modifications prior to shipping can take additional time.
We ship most orders via FedEx Ground and USPS Priority from our shop in Hayden, Idaho 83835. Transit time varies depending on the destination. Orders shipping to the PNW typically take 2-3 days in transit. Orders shipping to the East Coast typically take 6-8 days. We'll send you a tracking number for your packages as soon as they ship so you can anticipate their arrival.
We offer free shipping to the lower 48 for orders over $1,000. The best way to meet the free shipping minimum is to order your stove and flue parts at the same time. Check out our flue parts calculator to build your flue system, or drop us a line at firstname.lastname@example.org for help.
If you are near Hayden, Idaho and would like to pick up your order in person, you can avoid the shipping charge by using the "local pickup" shipping option. Pickup hours are by appointment only. We'll email you when your order is ready to coordinate pickup, or you can contact us at email@example.com.
If your order qualifies for free shipping and you'd like to pick it up in person, we'll reimburse you the amount we would have paid to ship it when you pick up your order. Please write "hold for local pickup" in your order comments.
Items in new/unused condition may be returned for a refund within 365 days of delivery. Special order items and custom modified items (crimped, cut, painted, etc.) are non-returnable. Refunds will be processed via the original payment method.
Shipping cost is non-refundable and customer is responsible for return shipping.

Due to the high-demand for our products, we run out of stock fast. We try to keep items in stock as much as possible, but some of our products may be on backorder.
If you’d like to ensure the quickest delivery of a product, you can purchase an item on backorder. We require 100% payment upfront to reserve your order. When we get inventory back in stock, backorders will be fulfilled first in the order that they were received.
You are welcome to wait until we have products in stock to make your purchase, but items on backorder sometimes sell out before the shipment arrives.
We ship to Canada direct. Our store checkout calculates shipping prices for most populated areas of Canada. If you live somewhere particularly remote, especially somewhere only accessible by air, shipping may cost more than our estimate. Feel free to email us at email@example.com before you order if you want to verify the shipping cost.
Stoves are heavy and air freight is expensive, so we do not typically ship directly to locations outside of North America. However, if you live overseas, you can have an order over $1,000 shipped for free to a freight forwarding company inside the Continental United States. Then you would need to arrange with the freight forwarder for delivery of your items. Some of our international customers have reported having a good experience with Shipito.
If you are shipping to a freight forwarder, please tell us in your order comments so we can ensure all of your items are shipped together.
All international shipments are subject to customs duties and fees, which are not included in your shipping cost, and will be billed separately. All prices and shipping costs are reported in US Dollars.
Our store checkout calculates our best estimate for shipping cost to the more accessible areas of Alaska and Hawaii. If you live somewhere particularly remote, especially somewhere only accessible by air, shipping may cost more than our estimate. Feel free to email us at firstname.lastname@example.org before you order if you want to verify the shipping cost.
If you would like to place your order now and arrange for shipping later, you can use the "Pay Shipping Separately" option at checkout. We'll pack up your order and contact you with the dimensions and weights of the packages, and some suggestions for shipping.
If you live in Hawaii or a coastal area of Alaska, it can be cheaper to arrange your own barge service with a company like Lynden Transport. Select the "Ship to Barge Service" option to cover the cost of shipping to Lynden Transport in Seattle, or another barge service of your choice in the Lower 48. Free shipping applies to orders over $1,000 shipping to the lower 48. If you choose this option, you'll need to arrange final delivery directly with the barge service. The cost of the barge service is not included.

WOOD STOVE QUESTIONS
A: Sizing the best stove to your space depends on the size of your space, how well your space is insulated, the climate where you’re spending the winter, and how you intend to use your stove. A stove used for primary heat might be sized differently than a stove used primarily for ambiance. It’s generally better to run a small stove hotter and more efficiently than to underfire a larger stove, since underfiring your stove can cause creosote buildup in your flue.
A good place to start your design is to run your space through our BTU Calculator, which is specifically designed for wood stoves in small spaces.
We've helped thousands of people find the right stove for their tiny spaces, including our own. If you need help deciding which stove will work best in your space, drop us a line at firstname.lastname@example.org and we’ll be happy to help personally.
A: Standard installations require 18” clearance on the back and 16” on the sides. This can be reduced by up to 66% with the use of a custom heat shield attached to the wall, or up to 50% with our Dwarf Heat Shield Kit.
Check out the Manuals and Downloads page to find the current Dwarf Manual and other resources for detailed installation instructions.
A: A basic heat shield should be composed of non-combustible material (metal or cement board) and have at least a 1” air gap behind, above, below and beside the shield. A heat shield can be as simple as a piece of sheet metal with a 1” air gap behind and around, attached to the walls around the stove.
Check out our Dwarf Heat Shield Kit for a factory shield option offering 50% clearance reduction. See our article How to Build Heat Shields for Wood Stoves for more details and other heat shield options.
A: Our Dwarf stoves are designed specifically for small recreational or temporary spaces less than 500 square feet like tents, RVs, boats, and tiny homes on wheels. The Dwarf stove is not certified (UL/CSA) or approved (EPA) for residential heating and is offered for recreational, portable, or temporary use only.
In some cases, local codes may permit use of a non-certified stove in a residential building. However, the US EPA prohibits installing new unapproved wood stoves like the Dwarf in permanent residential structures anywhere in the United States.
A. Yes! The stock legs, tall legs and wood storage stand all have mounting holes for securing to the floor. The legs come with hardware installed in the legs that are for leveling the stove. This plate / hole that is used for leveling can also be used to bolt / secure the stove to the structure.
A: Aside from basic tools to build your hearth and heat shields, and cut holes through your roof or walls, you may need:
- A complete flue kit and some additional pipe. Floo the Parts Robot does a great job at building a straightforward installation, or we're happy to help personally if you drop us an email at email@example.com.
- Chop saw or angle grinder with a metal cut-off blade for cutting pipe
- Sheet metal crimpers for adding new crimps or adjusting existing crimps to make pipes fit together nicely
- Sealant to seal the roof boot to your roof. RTV silicone works well for this. If you’re installing in an aluminum trailer like an Airstream, Sikaflex 221 or Trempro 635 can be used instead.
Installing a wood stove is a moderately advanced DIY project, so give yourself plenty of time, be patient and thorough in your work, and ask for help if you need it. Feel free to contact us with any questions you have about your installation.
A: We haven't tested the Dwarf's burn efficiency in a lab, but the firebox design is an adaptation of an existing design that tested over 80% burn efficiency, so we would expect similar results. See our article on Small Wood Stove Efficiency.
The Dwarf Design incorporates several features to make it as efficient as possible, both in burn efficiency (converting fuel to heat) and heat transfer efficiency (moving heat into your space instead of sending it up the chimney).
- Insulated Firebox: The firebrick lining of the firebox retains and reflects heat back to the fire, which raises burn temps and improves burn efficiency.
- Preheated Secondary Air Supply: There are two independent air controls on the bottom of the stove which are used to control your burn rate. Once your fire is going, you can shut down the primary air (bottom of the firebox) and feed your fire mainly with secondary air (top of the firebox). Adding most of the air supply to the top of the fire ensures that there's plenty of oxygen available for complete combustion (burn efficiency), as well as helps keep your coal bed from burning out prematurely.
- Baffled Firebox: The large baffle at the top of the firebox also helps with mixing combustible gases with oxygen (burn efficiency) as well as slowing down the hot gases to give them more time to radiate heat into your space (heat transfer efficiency).
- Airtight Construction: The Dwarf stove's airtight construction forces all the air supplying the fire to enter through the air controls, where you can tightly control your burn rate. Less efficient designs have relatively open or leaky air controls, which tends to send most of your heat up the chimney.
One common feature of EPA rated stoves that we have NOT done with the Dwarf is to restrict the positions of the air controls. Typical EPA stoves have the primary air control either welded shut or severely restricted, and have the secondary air propped open to prevent it from being fully shut. The idea is to force the consumer (and those doing the lab tests) to set up a relatively clean burn, fed with plenty of secondary air and little or no primary air. Unfortunately, restricting the air controls that way makes the stove more difficult to control, makes cold starts or restarting the fire from a few embers more difficult, and makes the stove unable to burn anthracite coal.
Since the Dwarf controls are not restricted, it's up to the user to set up a clean burn. Burning properly cured hardwood with lots of secondary air and very little primary air tends to produce a very efficient and clean burn. If you take a look at the smoke coming out of your chimney, you should see no visible smoke except when you first start the fire, or for a few minutes after adding a new log.
A: Pound for pound, cast iron and steel have similar specific heat values. Carbon steel holds slightly more heat than cast iron, but because small wood stoves have so little mass, the difference in heat retention is minimal.
The Dwarf Stove is primarily made of carbon steel, but there are a few cast iron parts included.
If you want to improve the heat retention of your small stove installation, check out our article on Wood Stove Thermal Mass for some ideas.
A: The Dwarf is a multifuel stove, so it can burn wood, anthracite coal, and any number of other solid fuels like pressed logs, pellets or corn (with a basket), or even cow chips.
Lots of our nomadic customers heat their rigs with foraged wood that they find in the forest. Many stationary tiny house dwellers stay warm with free firewood that they found on local buy/sell/free message boards.
For long overnight burns, we're especially partial to heat pressed sawdust logs like North Idaho Energy Logs that are available in our local area in North Idaho. Pressed logs are a regional product, so available brands in your area may vary.
Check out our article Fuel for Tiny Stoves for ideas.
Fuel needs to be cut small enough to fit inside your stove's firebox. Ideal size for the Dwarf 3kW is 6-8", the 4kW is 8-10", and the 5kW is 10-12".
FLUE SYSTEM QUESTIONS
A: If you are installing in a vehicle, you’ll most likely want our RV/Bus kit. If you’re installing in a tiny house or cabin, you’ll most likely want our Tiny House Roof Exit kit. If you can’t use a roof exit, we have a Tiny House Wall Exit kit available for stoves with 4” and 5” flue sizes.
A: We don’t want you to have to buy extra parts that you don’t need, so we only included items in the kit that most everyone will need. Since every install is different, most people will need different amounts of single-wall and double-wall pipe to complete their installations. You can purchase the extra pipe, clamps, and other fittings separately from your kit, so that you have exactly what you need and nothing you don't.
A: Pellet pipe is typically rated for maximum temperatures around 570 degrees F, which is well below the maximum normal operating temperature of a wood stove.
Solid fuel rated flue pipe is designed to withstand a 2,100 degree F chimney fire for 10 minutes. Using proper solid fuel rated pipe is necessary for the safety of your installation.
A. While some people get away with a stubby chimney that stays in place all the time, we recommend that any chimney installed on a structure that moves (RV, bus, van, tiny house on wheels, etc) be constructed so that the chimney can be removed for travel. This provides lower clearance, keeps wind and water out of your chimney, and better protects the chimney from being damaged by branches or road debris while in motion. See this article on detachable chimneys.
A: Single-wall pipe requires 18" clearance to combustibles. This can be reduced by up to 66% with the use of a heat shield. Insulated pipe requires 2" clearance.
A: 3” flexible aluminum pipe and a hose clamp works well, and can be sourced locally at the hardware store. Alternatively, if you prefer a more rigid pipe, our 3″ single-wall stovepipe female end fits nicely over the inlet of our direct air box.
A: All of our standard Dwarf stoves have drafted well with straight 40” chimneys in good conditions, so we’re confident that you can design a successful flue system for even the smallest spaces.
If you are using the oven accessory on the Dwarf 5kW (the Cookstove Combo), you may need 80" or more height above the oven top for good draft, depending on your chimney configuration.
If you have non-vertical sections in your chimney (i.e. you’re using 45s or a wall exit), you may need significantly more height to produce sufficient draw. Connecting a small stove to a larger chimney with an adapter can also interfere with good draw. If you’re not sure whether your flue design will work, send us an email at firstname.lastname@example.org and we’ll be happy to help.
A: In our experience, a 3" stove doesn’t usually draft well with a wall exit. If you’re installing a stove with a 3” flue, we recommend keeping the flue as vertical as possible to create the best draft. Stoves with 4" and larger chimneys like the current Dwarf 3kW, Dwarf 4kW, and Dwarf 5kW do work well with a wall exit, so we offer wall exit kits in 4” and 5”.
A:The male end of single-wall stovepipe (and the inner wall of insulated pipe) points down, which is the industry standard convention for stovepipe in a natural draft flue system.
It might seem counterintuitive since the flow is going upward. Wouldn't it be more likely for the flue gases to leak out if the male end is pointing downward? To understand why that's not the case, we need to explore how a natural draft flue system works.
The wood stove does not "push" the flue gases up the chimney like a forced air furnace or a car exhaust. The rising hot column of flue gases "pull" the gases below them upward. This phenomenon, called "draft", creates a negative pressure zone inside the flue system. The draft actively pulls combustion products out of the wood stove, and pulls fresh air in through the air intakes. As a side-effect, if there is any leakage at the joints, air will leak into the pipe, not out. So, as far as the flue gases are concerned, the direction of the male ends doesn't matter.
However, the direction of the male ends matters quite a bit for liquids inside of the pipe. Water vapor is a major combustion product of hydrocarbon fuels, so water can condense inside of the pipe, especially when the stove is first starting up and the chimney is cold. Smoke can also condense to produce a tar-like substance called creosote. These liquids will follow gravity and run downward inside of the pipe as the stove is operating. The male end pointing down is designed to keep any condensing liquids inside of the pipe. Otherwise, water and creosote would leak out at the joints and run down the outside of the stovepipe.
If you don't have to extend too far away from the exterior wall to miss the soffit, you can just us a 20" piece through the wall instead of a 10", and build some additional blocking to mount the tee support on to. See this photo for what that looks like. Or you can use only one set of bolts on the tee support bracket to get yourself a few extra inches off the wall like this.
The other option is to use two 30 degree insulated elbows to extend your chimney away from the exterior wall at some point above the tee support, usually as high as possible but just low enough to clear the soffit. See this photo for what that looks like.
A: Not yet, but we're working on it. Drop us a line at email@example.com if you want to be notified as soon as the boiler option is available.
A: Yes, direct air is available here. No, it’s not usually required, but it's a good option. A wood stove exhausts air outside, so it wouldn’t deplete the oxygen in your small space the same way that a catalytic propane heater might. However, if your space is very airtight, the stove might not draft well without a direct air kit. Also, if you’re trying to keep your heating as efficient as possible, feeding the stove with outside air could help keep your heat in the house, rather than sending it up the chimney to be replaced by cold outside air leaking in.
A: Yes, the wood storage stand has a cutout in the back to accommodate the direct air.
A: The Dwarf 3kW and 4kW aren’t big enough to make a useful oven accessory. The footprint of the stove is so small that you wouldn’t be able to fit a useful sized pan inside of it. If you want to bake on top of a 3kW or 4kW stove, we recommend using a dutch oven. Be sure to get the rear exit kit with your flue system so that you can use the entire top cooking surface.
A: Yes, but it brings the top of the oven (also a cooking surface) to about 47″ off the ground. With the standard legs, the top of the oven is about 38″ off the ground, just a tad taller than a standard kitchen counter. If you intend to use the top of the oven as a cooking surface, it can be awkward to use at 47″ high.
A: The Direct Air uses a standard 3" flange. You can use metal dryer vent from the hardware store, or use our 3" stovepipe that fits the flange nicely and matches the finish of the stove.
A: The biggest "approved" reduction (per NFPA-211) would be with an air-cooled wall shield, which can reduce clearances by up to 2/3. There is no tested standard for combining attached heat shields with wall shields, so while you'd think using them both together would give you even more than 2/3 reduction, we can't say for sure how close you could go in that configuration.
We may test that at some point in the future, but for the time being, I'd suggest going no closer than a 2/3rd reduction with an air-cooled wall shield.
A: Direct mounted air-cooled heat shields, like ours, don't significantly reduce the heat output of the stove. Our air-cooled heat shields isolate a hot zone between the stove and the shield, which causes the air in that area to naturally rise and escape out the top of the shield. Cool room air is drawn up through the bottom of the shield. The air circulation cools the shield from behind and picks up heat from the side of the stove. Since it's room air circulating behind the shield that's doing the cooling, the vast majority of that heat should end up in the room.
