Rancilio Silvia 110V Boiler & Heating Element



Rancilio has once again updated the Silvia boiler. This new version still comes complete with the brass boiler tank and element assembled, but the 110V, 800W element is now made of stainless steel and is removable. 

The elements are threaded and keyed, meaning that they can be installed and tightened with ease, using the included fixing nut.  They also include a wiring extension kit and the boiler to group o-ring.

Now also available to order separately the:

This part does not come with the thermostats. If you have the old version where the male connecting fitting for the Over Pressure Valve fitting is not removable. Rancilio discontinued the "kit", until they assign a new number for it that includes this updated boiler and element assembly. For now, all of the parts are sold separately:


Here follows the technical press release from Rancilio's infotech department, issued 08/2013:

"The boiler on the Silvia machine will be modified in July. The new boiler will still be brass but will accommodate a new type of heating element. The new heating element is steel, unlike the previous model which was copper. If the machine is used with a partially full boiler the steel heating element is more resilient than the copper. The heating element will be screwed to the boiler, and not welded, and a Garlock gasket (code 36220023) has also been added to ensure a better hold. This gasket is also used on the professional machines and is made with material that is resistant to high temperatures. To replace the old model of boiler you need the new boiler complete with the steel heating element (code 10705636 for the 110v version, and 10705637 for the 230v version). If you wish, you can also order the heating element separately (code 33110001 for 110v, and 33110002 for 230v). If you are replacing this part, remember to tighten the nut properly to prevent any steam escaping. Even though the heating element works well when the boiler is only partially full, remember to fill it after using the steam for a prolonged period of time."


The small black wire goes from the element terminal on the left (while facing the front of the machine) to the high-limit safety thermostat on the front of the boiler. The yellow wire goes from the right side element terminal to the steam thermostat (on the top center, above the high-limit) and to the orange indicator light.

Perfect Replacement

This replacement boiler and heating element went in without a hitch and I'm currently enjoying my first espresso from it. The boiler unexpectedly came with insulation (I had ordered one to go along with it so I now have an extra). I also recommend the thermal paste for the thermostats.

Thanks for giving me another 10 years with the Silvia!

almost a brand new machine

All parts ordered fitted perfectly. After a 3 hours job, everything worked perfectly. It's almost a new machine !

Works Great - with a couple of extra parts

The boiler itself is fine and it came with an insulating 'blanket' and the gasket. Before you take out your old one make sure to take a couple of pictures to ensure you put the wires back in the right spot. If you have an older Silvia where the water inlet/blowoff valve and the line going to the wand both come off the side of the boiler, bear in mind you're going to need a couple of extra parts: The new copper line from wand steam knob to boiler; a 1/4" BPT (don't try to buy this at the hardware store, it's not the same thread) double male adapter, and two to four copper washers. Coffeeaddicts were great to deal with and their shipping was lighting fast. Also great telephone support!

Rancilio Silvia 800W Boiler

The parts arrived on time. Excellent!. I wished the boiler come with a couple of OPV copper washer. I want to be able to adjust the OPV valve angle position. I had to repair the old ones. I still need one more washer to adjust the OPV for a better angle position. It would be nice if CoffeeAddicts could send me a couple of washers, otherwise the boiler seems to take longer to warm up. The old 1000W boiler heat element is welded and can be a health concern. It may be lead? I'm glad it got replaced. The inside of the old boiler was horrible. The water in Edmonton has plenty of calcium which makes me perform a full service of the boiler every two years or sooner. I added a water filter. The installation was easy. New boiler, electrical wires, stainless hex bolts, boiler insulation, re adjust OPV pressure to 9 PSI, painted machine case, new steam valve seals.
