Hi ya T/L
Good question as there isn't much difference between a RIMS and HERMS setup. The difference being with RIMS you are heating the mash directly as you circulate and with the HERMS you are heating it in the HLT via a coil. The way I see it as easier to control the temps as they are closer to the strike temps you are trying to achieve in the MLT. Having a insulated mash tun presents a few problems applying direct heat so heating the mash by gas or electric element would have to be done outside the Tun. I believe you use an immersion heater but I opted out of of this method as I expect to go over to a S/steel mash Tun in the future. (another keg). Another reason is that I can acquire 3/8" (9.5mm) annealed copper tubing through a friend in Sydney quite cheaply. Changing the subject, while I have been a critic of Moo Brewery's wheat beer and their Imperial Stout I must say I enjoyed their pilsener the other night. A very nice drop.
Cheers mate
