Like many, i have a Silvia with PID control on the brew temperature which works wonders at stabilizing the temp......
.....untill you pull a shot !
Then, as i guess we all know , the boiler gets cooled by the incoming water and the temp dives down into the 80s until the heater catches up and the PID settles her back at the preset temp. ..usually about 2 mins later.
I was just wondering if anybody had tried installing a water "pre-heater" system ( possibly a small thermoblock or "snail" heater unit from a pod machine) into the boiler water feed line to prevent this "thermal jolt" and help the boiler stay at the preset temp. ?
This could be simply powered from the pump "brew" switch to only power on when water is being transferred to the boiler.
Has it been tried / considered ?
Is it worth it ? ( IE: can you tell the difference in a few degrees temp change during the shot flow ?)
Any reasons NOT to consider this mod ?
IDEA ! .. Maybe i will just fill the tank with boiling water instead to see if there is any difference detectable to coffee taste ?
;D
