I saw a video on youtube which showed a wood stove being made from an old Calor gas bottle. It was inspired by a wood stove called a HotPod, which the orignal designer / manufacturer started out building from old gas bottles [you might have seen him on the TV show 'How to Pay your mortgage off in a Year' a few years ago], but he's since gone into business with a cast product using the same design - these sell for £2400 - £3000, depending on the model. Below is a photo of a real Hotpod which I found on the net at http://nbperuvianskies.blogspot.com/2007_06_01_archive.html - very cool!
Anyway, I liked the look of it (the HotPod and the one being made on youtube) so much that I dug out my grinder & arc welder, made a trip to my local recycling centre, & started to build my own.
Here's a photo I took on my mobile showing the first fire-up of my version of the stove.
This first burn was done in the back garden by my little shed in order to burn off the original paint from the gas bottle 'body parts'.
As you can see it's not the same as a Hotpod, but is rather inspired by the design.
I welded the flat top on instead of have it bolt on around the circumference. Also my legs are made from the gas bottle's removed base ring as I didn't have any stainless tubes to hand and I wanted to use as much of the original bottle rather than buy bits. My door - a glass saucepan lid, which held up to the heat just fine but we'll see! - isn't hinged either it simply lifts in and out.
I'd estimate that it cost me about £40 to build - £10 or so for the flat steel for the top and base of the ash chamber & the 8" pipe for the loading aperture, £5 for the straight 1 1/2" black iron BSP pipe fittings, £8 for the saucepan & lid and a few quid for welding rods, grinding disk and paint.
No. 1: Hotpod inspired wood stove.
And here are a couple of other stoves I've also made!
I don't do anything by half, do I?
Well, I had obtained 5 old bottles & wanted to play :o)
No. 2: Using the remaining 8" pipe to form loading aperture meant placing the bottle on it's side this time.
Just 2 more to go before running out of my gas bottle supply. Now where to put them? One in each room of the house!?!?! :o)
No 4. Copper door.
The large glass pan lid I had used for the door cracked, because I'd left the stove outside after its first burn and we had a little rain shower.
Raindrops are not good for a hot glass door!
All the designs are woodburners as they don't have grates. The wood fire simply sits on the base of the bottle and is fed oxygen via the low level air intake - which also acts as an air curtain for the glass doors. Wood prefers to burn like this (ie. air fed from the sides, the fire siting on a base of it's own ash) from what I've read on the internet!
To burn coal the fire would need to sit on a grate and have air flow from above & below the grate - maybe I'll do this for my last design and do a full copy of the hotpod air intakes / design!?!
