BACKGROUND
After launching the Dwarf line, we knew we wanted to add the functionality of a baking oven; a cookstove is the heart of an off-grid home! Our first two versions of the oven integrated the oven with the flue of the stove, allowing the flue gases to travel around the inner wall, heating the oven. What we found through use in our home and feedback from customers is that diverting flue gases robbed heat from the chimney causing the stove to lag in performance.
We decided to take it back to the drawing board and redesign the oven to keep the stove drafting better with a shorter chimney and slower burns. In testing the latest oven version (3.0) we were able to achieve all of our performance goals! We hit and maintained baking temps of 500F as well as top cooking surface temps of 300F. So far, Nick has baked biscuits and cookies inside the oven and has used the top surface to scramble eggs and cook soup! What does this mean? The oven is moving to production!
We are excited to heat, cook, and bake with the NEW Dwarf 5kW Cookstove Combo!
DWARF OVEN FEATURES
(still in development, specs may change)
- Simple retro-fitted top mount design – The new oven design will be easily mountable to the top of any Dwarf 5kW stove that uses the rear exit flue flange. Don’t already have a rear exit installed? No worries, read on…
- Compact rear exit adapter – The oven will come standard with a new compact rear exit that reduces the footprint of our standard rear exit by about 4”. (Note: a standard rear exit tee or insulated tee will still work with the oven though the oven cooktop temps will be slightly lower. The interior oven and stovetop temps will not be affected.)
- No additional flue height limitations – The previous version required a minimum of 120” of flue height in order for the oven to function properly. By removing the oven from the flue system itself, you are now able to use the oven with a wider range of flue designs and heights.
- Larger baking capacity – The interior of the new oven measures 13”W x 13”H x 11” D
- Improved cooking surface – The new cooking surface will now be made of cast iron and have a removable cooktop ring to allow for more direct heat to a skillet or pot should you need to achieve higher surface cooking temps. The new cast iron top will also extend out further than the previous version, giving more cooktop real estate.
- Heat shield upgrade option – The new oven will have mounting holes similar to those found on the Dwarf 5kW stove. These holes will allow you to mount our new oven heat shields or other DIY shields and accessories.
- Spring Handle

How's the stove's output? Just Right
What kind of structure are you heating? Cabin
My cabin project is moving along fairly well considering the actual time I have to work on it, but it is very livable & cozy with the installation of my Dwarf 5K stove & oven combo. I’ve been living in the cabin since early February, the day I installed the stove. I couldn’t be more happy with my decision to purchase this particular stove combo & also the help I received from your staff through it all. The process of calculating the right size stove for my project and the assistance in ordering the proper kit to complete the entire installation was top notch. Thank you all for your attention to detail!

i would like to know the size of Russell’s cabin. We are contemplating buying the dwarf 5k combo for our cabin and are unsure if it is big enough. We are in Northern PA.

Hi Lynn-
Russell was kind enough to relay some additional info for you. The cabin is 12’X24’ with a 4’ deck/porch so the interior is actually 12’X20’. The interior walls are 8’ framed with 2”X6” studs & R19 faced fiberglass insulation. The peak of the finished ceiling is 10’ with 2”X6” trusses & R30 faced insulation. It’s located in southwestern Montana approximately 5300’ elevation, so it gets a lot colder than what you’re likely to see in Northern PA.

Lynn, My cabin interior is also around this size, I have no insulation, just 4″x6″ D logs and R7.5 in the roof. I am in MN, so it does get quite cold here. It takes about an hour for the cabin to warm up to temp, and I typically keep a window cracked to modulate the heat as I do not use a damper. I feel like I definitely could have gone smaller, but do like having more available if needed. It’s easy to crack the window a bit wider if need be. These are very high quality stoves and you can’t go wrong.

Lynn, JB is right — you can’t go wrong. In my review I goofed up a bit. We are in central PA and nighttime temps have been in the low to mid-twenties each night for the last week. We fired this 5Kw up for the first time seven days ago. Our second floor temps are steady at around 68 degrees. Our house is 1625 sq. ft. and was born in 1928 as a “patch” coal mining home. The only insulation it has is 1/4′ styro-foam board in the walls and 4 inches of fiberglass in the upstairs ceiling. The only thing we added was one of the fans from TWS’s website. It provides quite a bit of circulation.

I’ve finally got my cookstove combo installed. There were a few hiccups with getting the right parts to connect everything, but TWS support was great to work with and got me squared way without too much trouble. Very happy with the initial impression of the stove and all of the flue parts. I’m running this in a 220 sq ft log cabin and the output is more than enough, even with only R7 roof insulation. Drafts really well, though still working on trying to get longer burns at night. Definitely do several (hot) burns outside to get the paint cured as much as possible.

Thanks for the question. Both the Dwarf 5kW and the Cookstove Combo (the 5kW plus the oven) use 5″ pipe.

I have a 1,020 sq.ft. cabin on the lake would the tiny Wood stove and oven keep my house at a comfortable temp. if power went out? The kitchen, family room and dining room are open. The 2 bedrooms are 11′ x 10′

Diane,
I’ll send you an email as well, but, in short, no. The 5kw stove that is part of the Cookstove combo is designed to heat spaces of 500 square feet or less. In warmer climates or with supplemental heat it can be a good fit for larger spaces but it just won’t be able to produce enough heat for a 1000 sq. ft. space by itself.

Question
Dan –
I love the oven idea, but is it still possible to cook with a cast iron skillet with the oven installed? I would think trying to use a skillet on top of the oven wouldn’t generate enough heat. Maybe placing a skillet on the floor of the oven?

Dan-
Absolutely! Being able to cook on top of the oven was one of our major design requirements. We didn’t just want a wood-fired oven, we wanted a cooking surface for a skillet, sauce pan, or kettle. The Dwarf Cookstove routes flue gases directly underneath the top cooking surface, which helps it achieve higher top cooking surface temperatures. We used an oval flue flange located toward the back, which frees up as much space as possible for a larger pan. We also included a baffle switch above the door, so you can bypass the cooktop for easier cold starts.
Since the flue gases have to travel through the body of the oven to reach the cooktop, it does tend to be a bit cooler on top of the oven than the bottom surface. The cooktop works well for low or medium cooking, like stewing or simmering. If you want to sear something hot and fast, your best bet may be to open the oven door and put a pan directly on the bottom surface of the oven.

Three Dan’s! Dan is correct. We have used the bottom of the oven for searing. However, for baking, it is a good idea to place the pan on a rack. Our first loaf of bread was baked on the bottom of the oven and was quite crunchy on it’s bottom. The next two loaves, I experimented with rack and rack height; the rack at the bottom level gave us perfectly baked loaves. We have done bacon on the top of the stove, but it is hard to crisp it. But, heating veggies and other stuff works great. We will not get rid of our range, but I think it is going to get jealous of the 5Kw.

How's the stove's output? Just Right
What kind of structure are you heating? Something Else
My wife got us started on this project. With her, we researched about a dozen “dwarf” stoves. Each had one or two features we liked, but not all.
Then, we saw this! We purchased a 5Kw combo. I did not listen when Nick advised me, in August 2020 to order pipe before it was out of stock. I should have listened. We are using it in a 1625 sq. ft. house.
Here is a rundown:
– first and foremost, Tiny wood Stove is the only company we have ever dealt with that has been with us every step of the way. These people are simply awesome.
– We did an “outside burn to cure the paint as soon as we unboxed the unit(s). If you follow the instructions in the manual, you will have no problems.
-we had to place it in a corner. So, we installed heat shields on two walls and on the floor. Additionally, we painted the walls near the shields with 1000 degree heat resistant paint.
– the pipe arrived last week and we had some issues outside. we did a thru-the-wall exit and had to try ti miss the eave and still maintain clearances. TWS helped and we got it done on March 14th.
– we used cardboard to burn for leak checks at all joints.
– temps, here in central PA have been in the low twenties since then during the day. This house has never been this warm. Yes, it heats the entire 1st and 2nd floors! The heat is consistent throughout, with no cool spots. Just warm, evenly distributed heat. We did purchase one of the nifty fans that helps immensely. We were very surprised. We had hoped this would be simply a little help to reduce fuel bills. But, the furnace is not needed at all! We turned it off.
– I also purchased one of their “laser” thermometers and checked all our work. Flue temp 6 inches above the oven stay pretty steady at around 350-400 degrees. The double wall pipe, as it exits thru the wall, has not come above 92 degrees. The shields are at about 160 directly to the side and back, but behind the shields it stays at a steady 98.2.
– if you opt for any of these products, pay close attention to the tutorials in the manual and also contact TWS with any questions. These people did their homework and we could not have accomplished this without their expert guidance. Because of their guidance, we have a solid understanding of flue design and function.
– OH! And was it ever easy to light! This is a high quality product. We both especially love the “tertiary” function.
Bottom line is that this is an amazing, high quality product backed by an amazing and professional staff. This stove package cost less than most other Dwarf stoves that had half the features.
Absolutely satisfied!
