  • I don't sell any of these nor do I receive any remuneration if you buy them, and I have not personally reviewed all of them, they are listed here to give you perspective

Introduction

  • these are well made high quality stainless steel stoves with a unique external air intake duct to reduce oxygen consumption within a mainly enclosed environment such as a tent by allowing this to be obtained from outside the tent
  • you need to also buy:
    • a flue brush cleaner of the correct size for the chimney 2.5“, 3” or 3.5“
    • a magnetic stove flue thermometers but these won't attach to stainless steel so you have to just sit them on the stove next to chimney
  • if using inside a hot tent, you also need:
    • fire mat $AU59-89 depending upon size and type (Carbon Fiber- Aluminum Foil rated to 400degC, cheaper silicone coated fibreglass rated to 250degC)
    • Winnerwell Triple-wall Heat Protector Chimney
      • if you use the Triple-wall Heat Protector Chimney only without the use of Flashing Kit or a fire retardant stove jack, there will be potential risk of melting or burning the tents especially if the triple shield is too close to the stove
      • must be installed on the third or higher than the third section chimney pipe of the stove. 
      • many people use a plain chimney section passed through a fire retardant stove jack without issues but you do need extra care the tent fabric does not touch the chimney
    • if no fire resistant stove jack and the tent is canvas then you may need a Winnerwell Flashing Kit
    • if the stove jack height is not the correct height for the triple shield section, you can buy a half height chimney section which may address this
    • if weight is an issue, then the Winnerwell Mesh Protector can be used instead of the Triple-Wall Heat Protector and is 500mm x 120mm diameter and 630g but flammable material should not be left in contact with mesh
  • if you need to put a bend in the chimney, you also need a support stand for the chimney.
  • optional extras:
    • water boiler (if you did not purchase the essentials pack)
    • pipe oven which fits between chimney pipes
    • flat folding oven sits on top of the stove (if you did not purchase the essentials pack)
    • extension legs for the Nomad
    • secondary combustion burner to generate more heat, provide more cooking surface and reduce black smoke (only available for the 3.1” and 3.5“ chimney models)

General warning notes

  • these stoves are NOT designed for keeping you warm while you sleep!
    • they need to be stoked every 30-60min otherwise they will go out and they need to be monitored as with all fires
    • they are not great for keeping you warm in open areas outside of a tent - you would need to be within 50-100cm to feel direct warmth
    • they are best used for cooking, boiling water, drying out clothes or tent, and for providing additional warmth inside a tent (although you may need to keep a door or two open to avoid excessive warmth)
  • FOLLOW the instructions to ensure you do not excessively warp it or break the glass!
    • temperature should be in the 250-370degC range or 500-700degF
    • ensure you do not overfill it with wood and block the chimney vent
    • only use dry seasoned wood as a fuel (hardwood is best)
  • ONLY use in well ventilated outdoor recreational areas such as tents or recreational shelters or outdoor saunas NOT for indoor use
    • although the external air versions may be OK in less ventilated spaces HOWEVER, when opening the stove door smoke can pour out so it should be well ventilated at these times, especially when initially starting a fire
    • ensure the door seal or the glass windows are not damaged
    • do not use wet wood as these increases CO production
  • ensure flammable materials do not come within 30-100cm of the stove or chimney
    • chimney requires a fire resistant stove jack in the tent ceiling when used inside a tent and you need to use either the optional triple shield section or the optional mesh guard at the level of the tent stove jack protecting BOTH the fly and the inner tent fabric
    • ensure tent and chimney are well guyed in winds to avoid tent material blowing onto hot part of chimney or the tent collapsing onto the stove, guying the top of the chimney will also reduce potential damage to base of the chimney in winds
    • running the stove very hot will increase risk of embers getting through the spark arrestor and melting holes in your tent fly
  • do not put on top of a tarp as a floor even with a Winnerwell fire mat protecting the tarp as the tarp will melt!
    • fire mats do not provide much thermal protection for the radiant heat
  • chimney pipes can become extremely hard to pull apart if bound with glazed creosote from prolonged low temperature burns
    • will need 2 people to pull them apart (don't twist)
    • prevent by avoiding prolonged low temperature burns
    • can clean the creosote glaze off with stainless steel spray cleaner and steel wool
    • can clean the creosote glaze off glass windows with either a dry steel wire pad designed for this, or wet method with a special cleanser fluid

External air models

  • there is only one model with no side windows and that is the WoodlanderPlus Large Ext Air, and unlike the standard series, there are NONE with only one side window
  • the chimney and chimney accessories are NOT compatible between the Medium external air versions and the standard Medium versions as the chimney is now wider

General sizing information

  • NB. chimney diameter is important as most of the accessories are designed for a specific chimney diameter!
  • the supplied 3 expandable bendable screw-on air ducts are designed to be stowed inside the chimney pipes for transport
  • Medium size
    • uses 76mm 3” chimney pipes (this is DIFFERENT to the medium stoves without external air which are 2.5“!)
      • NB. the spark arrestor section and one other adjacent section pipe is 73mm 2.9” so they pack inside the other pipe sections for transport
    • optional ext air medium pipe oven is 4.4kg / 9.7 lbs and has a baking chamber measuring 6.2“ x 6.2” with two internal shelves
  • Large size
    • uses 89mm 3.5“ chimney pipes (this is the SAME as the large stoves without external air)
      • NB. the spark arrestor section and one other adjacent section pipe is 85mm 3.3” so they pack inside the other pipe sections for transport
    • has approx twice the firebox capacity of the Medium version allowing larger longer burning firewood with more burning ash to maintain fires as they burn down
    • the larger amount of wood able to be burnt also means more heat output
    • but are about 50% heavier and more bulky than the Medium stoves
    • optional large pipe oven is 6kg / 13.2lbs and has a baking chamber measuring 7.5“ x 7.5” x 10.6“ deep (19x19x27cm) with two internal shelves

My brief review of the Woodlander Plus Large External Air compared to the standard Nomad Medium

Pros of the Woodlander Plus Large External Air

  • external air duct means:
    • you are safer when using it inside a tent, especially when there is minimal ventilation on those cold winter nights with no breeze
    • you can more easily provide extra air using a gentle blower into the duct without it producing a lot of smoke into your tent as would occur if you used a blower in the front air vent or the open door of a standard stove
  • the large size does allow longer wood to be used and it does burn a bit longer and produces more heat if you load it up
  • front door glass is larger as there is no front air vent
  • does not have the removable circular plate on the top so you get less smoke and CO entering your tent
  • does not have a chimney damper so you wont accidentally close it off and smoke your tent out and packs away better
  • you have to close off the air intake at least partly to open the door - presumably this reduces smoke or flames coming out the door?
  • has an extra top shelf inside the firebox which acts a bit like a secondary chamber to reduce black smoke - however in my experience it seemed to have more visible smoke than my Nomad Medium using the same dry seasoned hardwood
  • the tubular Woodlander legs are much nicer to open and close than the Nomad style legs
  • you can buy the mesh guard if you do not want to enlarge your tent stove jack holes too much when you also use a 2.5” triple shield chimney for your standard Nomad Medium stove, however the 3 wing nuts may force you to widen the stove jack more than you would like (the mesh guard which fits all models and sizes, without the wing nuts, are the same diameter as a standard Medium triple guard)
    • obviously if you do not have a stove with a 2.5“ chimney, then you can make the stove jack the correct size for your “optional” but highly recommended triple shield chimney section

Cons of the Woodlander Plus Large External Air

  • it is more bulky - even the Medium External Air is more bulky because there is a fixed duct intake on the firebox meaning you can no longer stow it easily on the floor of the back seat of your car
  • it is 50% heavier than the Medium stove which can be an issue for many
  • no side windows so less ambience if that is what you prefer
  • surprisingly, the front door opening is substantially SMALLER than the standard medium Nomad stove which is 17x17cm square - so you can't really fit thicker logs in, so most of the extra capacity it in the length of the firebox!
  • the absence of the top removable plate means you can fry directly on flames for higher frying temperatures - but you probably would not want to do this inside a tent anyway for safety reasons
  • I had considerable trouble getting it to start in cold conditions with no breeze
    • even using two fire starters and dry seasoned hardwood kindling, the fire starters would tend to go out very quickly due to smoke suffocation (this may be due to the long length of the intake duct not providing sufficient oxygen to get it burning or perhaps it is the additional shelf and longer path for smoke to go up the chimney - for all of this to work, you need heat inside the firebox to send smoke up the chimney and draw in fresh air)
    • I resolved this by using a air blower into the duct for a few seconds to get the fire hot enough to draw its own air, in addition, it seems important to put the fire starters BELOW the mesh and push them at least half way down the firebox.
    • I don't recall having this issue with the standard Nomad Medium with the front air intake
  • the accessories are much bigger and heavier - even if you get the Medium External Air as Winnerwell has made the chimney 3” (instead of 2.5“) for the Medium external air stoves
  • I had trouble getting the large pipe oven to 200degC - even moving it closer to the stove with only a short pipe section under it, the most I could get it to was 150degC - although this still burnt the top of my frozen Danish tarts which should have been OK in a 175deg fan forced oven or 200degC conventional oven so I suspect one may need to use lower than usual baking temperatures - for comparison, my Nomad Medium oven sitting on a standard chimney section would generally get to 200degC within 15min or so of having a hot dry kindling fire going.
  • it seems you are more likely to have longer periods of low temperature burns and perhaps more creosote build up
  • the wide pitch of the ash mesh allows more and larger burning to hit the floor of the firebox which results in the floor of the firebox being much hotter than in the standard Nomad medium and this mans you really do need to be careful what you have nearby on the ground - in any case with either stoves you should have a fireproof mat, but these do not stop heat transfer to under the mat and so tarps or tent floor material should not be under the stove
  • unlike Nomad stoves, there are no side hooks to hang the optional water boiler tank
  • the pipes seem much harder to get back into the stove for transport (the door is SMALLER!) - I gave up and left one of them out!
  • takes longer to set up and pack up as you have the additional ducts to join and un-join and pack away
  • the stove pipes are even harder to pull apart than the 2.5” pipes

Summary

  • if I did not have any stoves, and I intended to use the stove inside my tent then:
    • if the only space I had in my vehicle to stow it was the floor of the back seat of my car, then the standard Nomad Medium would win and I would ensure the tent had at least two large windows or doors open during use given it is not an enclosed system like the external air models are
    • if I was using it in a very small tent such as a Pomoly Leo 2 2P hot tent then the standard Nomad Medium or perhaps the External Air medium stoves would be the best
    • if I was using it in a large tent or I wanted to bake larger foods, then the WoodlanderPlus Large would be my preference, but for direct heat warmth and ambience you may prefer the double view versions if you don't mind the extra 2kg weight
