FOR NEW VERSION BOILERS ONLY Rancilio new version 110V, 800W element is now made of stainless steel and is removable. That's right, no more brazed elements. These are installed in all new Silvia models beginning in July 2013. This elements is threaded and keyed, meaning that they can be installed and tightened with ease. Includes R_23 (36220023) gasket, but does not include the fixing nut. 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."
