New electric 50L setup

[barneey]

Last question first = Bobsbeer found a brush (bottle cleaning type) which fits perfectly down a 15mm copper pipe, strangely these are sold on a website that specialises which "Goat" products / welfare = The name stuck "Goat"

I`ve tried many time to "convolute" copper pipe, there is a thread on a US site where "one" person managed to produce a home made version, the details of how it was achieved weren't exactly forthcoming.

FUBAR on here mentioned about using "olives" soldered in place to disrupt the flow of water, I used these in conjunction with my own "convolute" method (forming rings on the 15mm tube) so as can been seen both the outside and inside of the pipe have the flow inhibited.

HLT and the HERMS coil before fitting


Love this
How did you bend / fabricate it? I'm wondering how thick are the walls to achieve good bends like this?

cheers

Thanks Frothy,

The pipe is 'standard' 10mm o/d copper, as available from most diy stores - it seems to be about 1mm thick wall.

For this coil, which is about 400mm diameter, I just placed the coil (it comes in a loose coil already) on the floor, at 90 degrees to as shown in the pic, and gently pushed it down, then turned it a little and pushed down again. Not sure if that makes sense!

When I've made smaller diameter coils I've just used something of a suitable diameter, like a large paint pot, and done the same sort of thing around that. That seems to be the way most people do it from threads I've read.

Thanks Rob for the pic of the pic of the sparge arm, Im going to modify my design based on what youve done - appreciated.

FYI Im going to add a small stainless steel ball valve in line with my unit - i can then adjust the sparge rate much more easily without having to bend down to adjust the pump valve...
