Want a warm toasty house through those long winter months?
Do you love entertaining outside next to a warm, welcoming fire or cooking on a barbeque?
How about relaxing in your wood-heated outdoor hot-tub for those starry nights?
We can help you do all these things,
better and cleaner than ever before
Rocket heaters are the smart, safe and sustainable alternative to a standard combustion heater. A rocket heater uses 50-90% less wood than a combustion heater and also the emissions are said to be 100 times lower than a combustion heater. These numbers can be very hard for people to grasp or often simply don't believe the numbers but to understand, you need to understand that rocket heaters are a completely different beast to a combustion heater. A rocket heater encompasses rocket mass heaters and rocket stoves. Rocket stoves are cooking devices used exclusively outdoors. There is some confusion as Americans will often refer to "stoves" when they mean a heating device. This has confused people over the years that think a rocket stove and rocket mass heater are different when it's just what Americans call a heater...a stove
Rocket Mass Heater in a Tipi
This was an experimental project in Missoula Montanna (Just South of Canada).
The idea was to build a RH in a structure with little to no insulation and see how people would live through a Northern American mountain climate winter.
They were quite comfortable. There is a full article on The "Permies forum" which you can read here.
What we can do for you
We Can build various styles of heater such as a J tube or a batch burn heater either inside or outside. We can build a heater into a hot tub or an outdoor kitchen stove.
We can also just provide a heater core for you to build your own creation around. We can provide plans along with the core for building your own. If you just want to purchase plans and go on your own, I can highly recommend heading over to www.walkerstoves.com.
We are happy to build anything from Walker stoves, so if you see something you like, please let us know
6" Walker Stoves Super Hot J Core (including a set of plans)
Flat packed $500
The 6" Walker Stoves Super Hot J Core is intended to be be used either as the firebox for a Rocket Mass Heater or OUTSIDE as a rocket stove (for cooking). It's made from a lightweight super-insulated material called ceramic fibreboard. If you were to use this as an outdoor cooker, the ceramic fibreboard would require cladding to protect it as the material is very soft.
If you want to purchase this as a flat pack, we will supply you with instructions and glue.
If you purchase the core pre-assembled, we can deliver it for a fee within the greater Sydney area or you can collect it from Springwood NSW 2777
Postage is $30 for the flat pack and $60 for the core assembled (when assembled it will be in two parts (burn chamber and riser)
This is a video of me talking about a previous workshop.
You can see the core in the video. The bricks around the feed are to stop the ceramic fibre board getting damaged whilst putting wood in to burn
Walker Stoves Brick Rocket Mass Heater
The Brick Rocket Mass Heater features the ceramic fibre core (featured above). It can be built with or without a bench and holds heat for around 8-12 hours (after the fire completely goes out).
The heater comes with a set of plans.
The cost for us to build one of these is $2000 without the bench or $2600 including the bench
Walker Stoves Batch Rocket Mass Heater
The Batch Rocket Mass heater is similar in size and heat output to the brick J-tube design (above) but the heater has a small glass door where the wood can be loaded and the fire viewed in a more traditional manner.
A freestanding batch rocket would cost $3500 and $4100 with a bench.
We can run Rocket Heater builds as a workshop on your property for you to recoupe some of the costs.
Having workshop participants helping with builds is a great way to learn but it can sometimes slow the work down. On the other hand, it could also be helpful. It really depends on the crew.
How long does it take?
We include 3-4 days of onsite labour (depending on the style of heater you choose) so if this time frame runs over (due to workshop participants) we would charge by the day to rectify any issues with the heater before leaving it in your care. We can help promote the workshop on our facebook page/website.
How much should you charge your attendees?
A good guide price to charge people to come to a 2.5-day workshop (Starting Friday night and running all day Saturday/Sunday) is between $100-$150 (excluding accommodation and food) although it is up to you. We can only accept 7 people maximum.
