if any one is thinking of going HERMS Aldi have a 8.8 ltr urn for $40 starting Wednesday. could be a good HX.
That's my plan (I got one last time they were on sale) so I'd also be curious to know if the PID might not do good thing to the element or the urns internal-controls.I reckon these would be pretty good as a heat exchange for HERMS. Could anyone see any reason why you wouldn't use one? Would the switching on/off from the PID be no good for the urn's element?
Just the info I was after, cheers FB.Fat Bastard said:I bought one a month or so ago for heating sparge water, and they'll boil the full volume in about 10 minutes. You can replace the stock tap with a 1/4" ball valve using a 1/4" nipple, elbow and a coupe of washers super easily.
Going off the full volume mark and using the elbow as a pickup, you won't get more than 7litres out of it though, the 8.8l figure must be measured using the outside dimensions.
Been pretty happy with it so far, and will turn it into a HX at some point. Might even try a small batch BIAB.
Should be fine as long as the urn's controls are turned on full tilt so they're not kicking in and out. The element itself will not be damaged unless you're running dry.Wolfy said:That's my plan (I got one last time they were on sale) so I'd also be curious to know if the PID might not do good thing to the element or the urns internal-controls.
Slightly off topic where did you get the rotating sparge armFlorian said:Just the info I was after, cheers FB.
Have been using the Aldi urn for ages to heat up sparge water, but got one of those rotating sparge arms a few weeks ago and needed to find the right size ball valve to connect it all up. Should have it all setup for the christmas break.
