Posted Sun Nov 25, 2012, 2:58pm Subject: Does anyone have the new Giotto Evo with the insulated boiler, yet?
If anyone has one of these, already, could you tell us the cycle time of your boiler element? Does that thin, black vest on the boiler make a significant difference to the boiler holding in its heat? Rocket Evo I know older Giottos seem to cycle (From p-stat click on, through off, to click on-again) in just under a minute. Additionally, on older Giottos, if left on for 5 hours or more, the reservoir water becomes disturbingly warm. Does this insulated boiler help with that? I'm more concerned with the cycle time than the reservoir temperature, simply for the promise of potentially extending the life expectancy of the pstats. Even the good commercial pressostats they've finally started using in these machines are really subject to failing after their rated 500000 cycles. Even if jumpered across both poles (North american 120VAC machines only, with the spare pole) to potentially double their life, that's only a million. One cycle/minute times 60 minutes times 13 hours for a machine that's on 7 AM to 8 PM... Gives you 780 cycles a day... That's 3.5 years per pressostat... I'd love to know that the insulation is helping to protect components without having any negative effects. Anyone have one yet?
