I got this far with my RIMS - currently looking for a false bottom solution before I can really use it as I've currently got a copper manifold in the MT

To prevent the bottom of the grain bed compacting around the copper manifold I could use my current mash tun feeding into an under-back with a float switch but it's not an ideal situation.
Was hoping to collect current RIMS "users tips" on running a RIMS in this link, as many build but there is very little info on the brew-day forum tab about actually running with one. Mostly Americans seem to use a HERMS coil in their HLT and it's primarily for keeping a stable mash temp rather than stepping the mash - which a RIMS has the power to do. Running the unit recently on my HLT recirc I was quite surprised how long it takes 3kw to raise 1degree on a looped circuit - guess there are some substantial heat losses from pipes etc.
