Thinking of adding a PID to Gaggia Classic...
I get consistent shots, thats the biggest advantage. And I can tune the temperature to match the blend. The preheating is described in this thread "Preheating the incoming water on a Gaggia Classic"

Thinking of adding a PID to Gaggia Classic...
I have a PID on my Classic since 1.5 years now and I am very happy with it. You will not get stable temperature during shots but you will get consistent temperature from shot to shot and that is worth the PID in my opinion. If you want, you can go even further by preheating the incoming water to

Why not a basket with roughened sides?
I have been thinking in the same way, and have been thinking about roughing the inside of the filter. Keep us updated if you perform any tests

Preheating the incoming water on a Gaggia Classic
They will certainly increase the water temp, but the question is how much ? If one wants to build a heat exchanger the temp of the boiler needs to be much higher than for the single boiler. Therefore I went for a chamber that holds enough water so that the temp is stable during the whole extraction

Preheating the incoming water on a Gaggia Classic
Here is a higher res version of the graph {link} I was thinking of heating the water with resistors too, but I gave it up because of the high wattage needed. As for tempsurfing with the classic, I never botherd to learn it. There are two different variabled that need to be controlled. The first

Preheating the incoming water on a Gaggia Classic
Yes - I milled the parts myself. It took a while due to the complex shape. OK, I will try to describe my PIDing of the Classic. I bought the connectors from a swedish supplier of pneumatic equipment called Hydroscand, the manufacturer is Metalwoks i think. I think you can find other suppliers of the...

Preheating the incoming water on a Gaggia Classic
I didn't want to hijack another thread so I will tell my story here OK heres the story.... During extraction cold water enters the relatively small boiler. This results in a 6-8 C drop in watertemperature during extraction. My idea was to preheat the incoming water to reduce this drop. The easiest w...

Worth it to PID a Gaggia Espresso?
I PIDed my classic a year ago and do not regret it. The main advantage would be the increased shot to shot stability. It is also much easier to fine tune the temperature. Another problem with the classic is the small boiler. The temperature during the shot decreases about 6-8 C. This can however be ...
