My obsession with temperature all started after I installed Eric’s T.C. Adaptor. I was flushing 8 ounces of water to get to the top end of brew able temps. In between shots I still needed to flush 6 ounces at least to keep everything cool enough to brew nice tasting shots. I was using lot of water, almost a gallon per day. I even have an external tank but that is another story.

Not only can I see the brew temperature with Eric’s T.C. adaptor, I can also see what temperature the group was at idle, 220º.

i researched and found about the thermosyphon restrictor that can be inserted in the thermosyphon to make the group cooler.

I contacted WLL no luck (long story). I contacted Expobar Spain, they told me to contact WLL. Once again Eric saves me and convinces me to contact Expobar Australia. I reluctantly do, totally expecting to be blown off.

A week later, I receive a thermosyphon restrictor in the mail. i did not change anything setting on the machine. All I did was add the restrictor to the top tube of the thermosyphon loop.

• long flushes (more than 8oz to get down to temp, if idle more than 10 minutes after initial one hour minimum warm up)
• temp seemed less stable

• shorter flush to get to temp (about 4oz, if idle more than 20 minutes after initial 1 hour minimum warm up)
• the temp seems more stable
• the dynamic changed a bit on what temp to stop at and what that will give me in the PF.
• the rebound is a bit slower now, but I still haven’t been able to out run it.
