Hello to you all. First time brewer here.

I have a little experiment

Instead of using Cooper pipe I thought using small car cabin heater. Mine is old and dirty but it is just to prove the theory.

Dimensions are 17x17.2.5 cm with two 16mm connections

Surface area is exactly the same as surface of copper pipe 8m long 14mm in diameter.

Water: 10L at 100C
Water was running medium speed through cooler/radiator

Temperature of water 20C

From 100 to 20C in 13min

You have diagram in pictures.


This is and old car cooler only for this test. There is a new one from the box waiting for your opinions.

There are models twice in size that I believe could cold much more wort in same time.

There is also option for placing one like this in bucket of ice before the main in the wort.

Sorry bro/girl but it would be so unsanitary and likely containing lead or something else not foodgrade that I would spend the hundo on a plate chiller and never look back.... Sorry for bashing the idea but your not the first on the forum to ask... Happy brewing dude/dudette...!!!

Here's a similar thread you can check out. But as already said, it's probably not a good idea.

Run. Run away from this idea quickly. Lead = dead (or at least very sick).

I am the dude. What led people. It's made purely of copper welded with zinc-silver. You really believe stories tha lead can melt in 100C or less. Seriously? This is copper and it's working good for me. Plate chiller is way to expensive. Thank you for opinion.

There is a reason that the developed world has gotten away from lead water pipes. Even cold water can pick up traces and it doesn't take much to give you lead poisoning.

The Heat Exchanger may be made from copper but it was probably soldered together with lead based solder since it is not required to carry potable water.

The other concern is that if you are using a refurbished Heat Ex, it is probably impregnated with ethylene glycol which is very poisonous.

If you're dead set on using it, use it to chill the water/glycol that you use in an Immersion/Counter Flow/Plate chiller. Just make sure to test for leaks periodically.

zinc can be a problem, but I am sure you know that already

Don't go ruining an argument with sense and logic

I'm all for being cheap and saving money but there are too many variables in using something like that. Just because food grade components might be used doesn't make the end result food grade. Companies are not gonna take the time and effort to spend extra money on stuff like that.
