Detailed description

The WS-400 is compact enough for carrying strapped on top of a rucksack or packed into an ahkio. The feet fold neatly away for transport and are quickly deployed for operation, the cutouts on the bottom of the feet allow you to use long pieces of wood as a base for the stove – raising it higher up for easier use and better heat emission inside a tent.

With the 80 mm chimney pipe port in the middle the top of the stove offers two high temperature surfaces for cooking on. Never fry or cook any food directly on the stove itself though, always use a pan or pot.

The oval shape and assembly methods result in a very strong construction, making the stove stable and resistant to dents and deformation due to heat, even when red-hot.

 

Clean and efficient secondary combustion

More heat with less firewood and almost zero harmful, and wasteful, emissions. A secondary combustion, or secondary burn, stove is designed to ignite the gasses emitted from burning wood which then turns them into thermal energy. In practice this means more warmth within your tent and far less wasted energy and noxious gasses blowing out the top of the chimney. This is a very good thing!

The WS-400 stove features a clean burning and very effective combustion process: Primary air enters from the front and back of the stove directly under the fire grate. This enables rapid ignition and steady combustion. Pre-heated secondary air is introduced to the stove’s top section through a flame plate in the door. The secondary air raises the combustion gas temperature, producing cleaner combustion at higher temperatures. The location of the gas combustion under the hotplates also accelerates and enhances their performance.

 

Instructions and warnings

Never ever leave a hot stove unattended and always keep a bucket of water, fire extinguisher or fire blanket within an arms reach from the stove when using it. Never touch the stove without proper protective gloves when it is hot, and remember that it does not need to be glowing red to be hot enough to cause serious damage if touched.

We recommend using max. 35 cm long pieces of firewood for easy and efficient use. The WS-400 burns best when half full of firewood, you should never stuff it full as this seriously hampers the combustion process. After use let the stove cool down properly, remove the fire grate and shake and clean out any ash from within the stove body.

Make sure you don´t leave any hot embers on the ground, use snow, water or any other available liquid to douse the ashes thoroughly to prevent a possible fire from starting. Reinsert the fire grate for transport, dry the complete stove if necessary before transport and storage. Never use any oils or fats on the stoves surface as these may combust and cause serious damage.

If you are using the stove to dry wet clothing, footwear or other equipment be very careful not to let these come in touch with the stove and always place them far enough from the stove to keep them from being damaged from the heat or even catching fire.

 

The HAWU story

The origins of the Hawu tents dates back to 1993 when Pasi Ylirisku, current CEO of Hawu Pro Oy, and his associates began developing a new tent design. For over two decades they tested and improved the Hawu tent to perfection in a true labour of love.

In 2016 Finn-Savotta Oy and Hawu Pro Oy signed a partnership agreement, the Hawu tent design was finalized for serial production in co-operation with Savotta’s designers and the original Hawu design and development team. The first batch which was completed and released for sale in the autumn of 2017.
