I purchased an E3D V6 about a month ago and want to upgrade to a Volcano. The V6 includes a 30 watt heater. Does the Kit #1 for Volcano have the same wattage heater or is it higher? Also similar question on the thermistor. I don't want to spend more than I have to, so £51 for #1 or £25 for #2? 1) Plated Copper w/ heating element and thermister VOLCANO-STARTER-COP-12V-175 2) Volcano Upgrade Kit VOLCANO-STARTER-12V-175
