In our view 30 gallons and under is considered hobby size. Do not bring anything larger then this to our site

Shotgun boiler (not condenser)

Postby Stew8 » Sun Jan 14, 2018 5:48 am

Was reading about alcohol burners and found this on eBay
What was interesting was the kettle, the opposite of shotgun condenser.
I’m considering building a new boiler and thought adding extra copper pipes vertically in the same way as the kettle shown in the photos.

Any thoughts?

I’ve taken screenshots so when this is eventually pulled from eBay you can see what I mean;

It would absolutly give you faster heat up times if you were over a fire for a heat source. But to be honest with how much extra work and how many potential leak points you are adding to a boiler that is going to contain hot alcohol over a fuel and ignition source it wouldnt be a modification I would make. That however is completely up to you what you do with your boiler.

If you do I would hover suggest a detailed build.thread with lots of pics.

If you’re going for flavored spirits you’d be better off slowing down your heat up times...

Thanks for replies;
Yak - thanks it is much more or a risk I’ll need to either improve my soldering skills or use tank compression fittings $$$$
Given the direct flame in the joints the lower joints may need to be compression fittings.
I’m going to research it a little more as there is lots of info on shotgun cooling that is applicable to heating.

Rakete I’ll need to read on how heat affects flavour as I’m a real newbie. My shed sits at les than 10c (50f) for most of the year so Was thinking of a way to improve the efficiency of heating the wash almost to temperature and then backing off the heat during the run - low and slow

Thanks again :thumbup:

Flaring and then flattening a 1/2 or 3/4 in copper pipe may make it easier to solder in the floor of the boiler. Not sure what to do at the top yet... :eugeek: :eh:

A fire tube boiler is efficient, but I'd hate to think about cleaning up the mess from burnt mash :roll:
And there would always be burnt mash above the liquid level in the boiler.

Thanks for highlighting the cleaning side of my things, and it would probably scorch above the ‘waterline’ being so hot.
Ideal for boiling water but not mash...

But that is a freaking rad tea kettle! I'm gonna make one!

Btw, no need for comp fittings, as long as it isn't boiled dry, you'll never melt a soldered fitting in contact with the wash. It's the old boil water in a paper cup trick.

And "dimpled" holes in the base of the boiler would reinforce those joints so they have more to bond to than just the thin base metal.

I agree. A little research showed that's (likely) a turn of the 20th century tea kettle made by Thompson, Ritchie & Co. designed for quick heat-up. Especially for picnics and camping trips. Brits HAD to have their tea, even on the go.
Looks modestly steampunked!
Here's an article on that style of kettle: https://www.worthpoint.com/worthopedia/1899-copper-kettle-thompson-ritchie-457918446

A lot of people think the serie Moonshiners is nog good, but there Mark and Digger build boilers with a horizontal pipe through them. But then of course you also need a horizontal burner. They wanted to avoid scorching and apparently it worked, because they repeated the trick.

Thanks all for the info,
ZA@ I’d forgotten about the paper cup idea and the frustration of trying to fix leaks in heating systems that would not drain completely. What was new to me was dimpling, I’ve got to try a diy tool ....just for the hell of it. :thumbup:
Kareltje@ it was that same moonshiner episode that has got me thinking of how to do this. Looks like empirical experimentation is required :eugeek:
If only I did not have a day job getting in the way......
Fizzix@ thanks for the additional info

Found a link on how to make a fire tube kettle which is an interesting read.

Fat, stubby shotgun condenser too.
