is not the right thing. Sorry.

You'd need to get a bigger relay to be sure it will be reliable. No sense in installing another that will need replacing every few years. You can get a decent Omron one that is designed to operate on the 120VAC that your machine is already providing through the pressostat...
If I can find pictures of an install and a  part number I will post further after the weekend.

Posted May 2, 2013 link

I looked at some Omron options (G3NA+Y92B and the G3PA+G32A) and their ambient operating temperature range maxes out at 80C. Not to mention, load current at 80C drops to 6 or 7A for the 20A relay models.

I don't know how close the relay sits to the boiler, but at 1.1bar the boiler will be radiating heat at about 122C. I would definitely be concerned about the performance of the relay while it is encased within the machine. Perhaps if the boiler is well-insulated, this isn't really a problem. The relay itself cannot be insulated as it is also a generator of heat and must have open ventilation/air in order to cool itself.

I would like to switch to a solid-state relay in my Cuadra, but these operating numbers are worrisome to me.

Yeah, that looks way too close, there's no way a solid-state relay can operate in that location safely.

If one were willing to run the wiring elsewhere with better insulation from the boiler, this could be possible; but I haven't opened up and looked around for space inside my cuadra yet. I am interested in insulating my boiler in the future. So that may help improve the situation.

On a side-note, I bought some GE silicone II caulking in a small tube. Gonna seal up my drip tray later so I can ditch that plastic liner. The sealant is rated to 400F, more than enough for this application. And it goes on clear, so there's really nothing interfering with aesthetics, either. Win win!

I would mount it between the water-reservoir carrier and the curved back wall.  One hole drilled through the reservoir-holder if the top-left(From front) corner is enough to bolt the relay on to, through whatever is becoming the protective cover.  Any bit of thin sheet, or even duct tape would do to protect it from water so long as it's bolted to the good sheet-metal heatsink of the reservoir-carrier (I'd use thin sheet metal from a beercan to make the cover, that way I get to enjoy a Guinness).  The metal reservoir carrier makes a decent heat-sink. The bulk of the reservoir protects it from infra-red radiation off the boiler.  It works just fine.

The relay I always use is the Omron G3NA 220B.
I don't know how to put up photos on this posting, but if you want to fire me an e-mail, I can e-mail you photos of the first one of these I did with a metal protective cover rather than the plastic (And packing tape) protection I had originally been doing this with.
I have done this upgrade at least 10 times, first had to be a couple years ago.  Apparently no problems yet.

I tried Redbird today after not having had it in a year or so. My overall impression hasn't changed. It is still good, but not my most favorite. It has a decent nutty flavor, but not as much of a chocolate bomb as I prefer. Maybe it would change some with dose/temp.

I took a couple of naked PF coffeeporn photos, but this site image handling just makes me pull my hair out - so no images to share.

I have two lbs coming today and will try it. My favorite is still Vivaci and then its a toss up between Klatch, Intelligentsia and Verve . There have been days when Vivaci just really blew my mind.
He ( David Schomer) only has two coffees Vita and Dolce..I will enjoy the Red Bird.

I have not heard of Vivaci. Are you buying the Vita or Dolce?

I buy the Vita. Remember what tastes awesome to me may not to you. I am not a coffee expert...I am a coffee junkie.

LOL. I wasn't planning to come punch you in the nose if I didn't care for the coffee.

I may give it a try after the redbird. Always looking for something new.

If you dont like it i will be surprised. Red Bird came at noon but I had  already worked my way through 4 double lattes of Verve. Between myself, my wife and son,
cranked out 10 double lattes. I made last four with Red Bird but didn't drink any. Tomorrow I will drink some...Pulled very nice shots though. Two doubles are sitting
in disposable 16 OZ mugs to be turned into ice coffee later. Take those add some Tornai and ice and milk...and wow. Love my espresso machine. Oh .. I wasn't worried about you punching me!!! LOL
