jaffle cooker + water heater, I was bored ok

[Blknight.aus]

So today saw me in the garage, I was ment to be fixing a chainsaw..but you know how it is in the garage, early on a sunday morning, the good looking girls are walking the dogs Im doing the smile and wave thing not really in the mood for the chainsaw it was being finniky so while on the perv I was bored and thirsty.

Bored and thinking about the upcoming camping trip, the last one I did, and the hot water routine for getting washing up water and showering water... hmmm thirsty... so off I toddle to the kitchen to grab a cordial.


stubbed my toe on one of edddo's rotors, Ok so I was in the japanese safety boots, my fault, then i thought heater.... what else have I got laying around...

heres what I scrounged up...
1048
Edddos rotors, some 13mm copper tube, some steel bar, a SWB brake drum and a broken chip fryer skimmer.

The blue water drum was the result of a trip to the markets. The intent is to mod it for the storage tank.

heres what I made

1050
1051

I should have checked the drum before I bought it. It didnt have the hole drilled out for a tap, no harm no foul, I used my water jerry instead.

1052


one chunk of wood about 20 cms across and about 20 cms long was split up into kindling and firewood..

the first bit burnt a bit funny and lasted about 15 minutes but left me with a good bed of coals around the drum,

the second lot burnt very well with little smoke and began to raise the temp of the water in the jerry

the third lot burnt just as well, made a really nice jaffle and blew off the hose on the pipe.. The heat had caused the garden hose I was using to collapse where it was bent over the lip of the jerry and the water boiled in the pipe softening the hose enough for it to slip off.

no loss it works... and should be better once I get the feeds for the drum sorted.

I wonder what tomorrow holds.

I love it, just put a tap on it as well and you have instant hot water urn

[Blknight.aus]

the plan is to have it as a changeover system...

the tank will have 4 holes in it.

starting at the top
the top one will actually be plumbed to the bottom of the tank, you pour your water in here.

the next one will be where the water comes out hot water rises so as your cold water goes into the bottom the hot comes out

the next hole down is the hot water return from the heater coil

the bottom hole is the supply to the heater coil,

The whole thing works on convection and as there is no way of getting water out without putting water in providing you dont get greedy, you never run out of hot water.

As a side thought It should also work well for boiling off drinking water as you will get sedimentary action in the tank and continuous heating... I could add a second set of coils into a bigger tank of water (non potable perhaps) to cool it down again... hrmmmm................

hmmmmm has given me an idea ,just need to convert it to a gas ring (no fires allowed on fraser)and bob s your uncle:cool:

Nice thinking there.

[hiline]

looks good :D

but i'll stick to my little tin bucket on the fire:D ;)

normally takes 10min to warm up

[dobbo]

and when it's not in use you could make a still out of it:wasntme:

[Blknight.aus]

beat ya to it ferno, the brake drum on the bottom comes out and theres a little wire platform there for the gas ring to sit on, takes the medium sized one that is just marginally rounder than the large protrusion of the rotor the coils mount on.

The Idea of it was for 2 birds with one stone... I get to cook jaffles and heat water all at once... If I need hot water instantly I could always fire it up and then put the kettle on top of it.

[Blknight.aus]

when I get it all worked out I still have one rotor and drum left over....

the cost of the other bits so far is under $20

[abaddonxi]

Now how do you make heat the chip fat as well?

:D:D

Waste vegetable oil preheater too!

Cheers

Dave, how about wrapping the copper piping around the exhuast, just below the maniflold, waste heat, and exhaust cooling all in one, and you have hot water when you arrive. Mount the holding tank some where safe.

shorty.

[Blknight.aus]

Done that too but not with that intent in mind

SWMBO always complained about the effectiveness of the summer heater of the series so I wrapped some pipe around the verticalish part of the exhaust and then made up a small tank with a series of sbends on the roof of the rover (much like a solar system). did quite a good job and offloaded about 5l of water every 200km and kept the floor pan at a reasonable temp..

someone asked me what it was when I was topping it up and being a smart ass I said it was a water heater.... It was but not cause thats how Id designed it.

[DEFENDERZOOK]

all that needs is a steam outlet and it can make capuccinos as well......
