I considered posting this on the ACE boiler thread, but that thing is already a behemoth, and I would rather this was easier to find. lol So, finally gotten around to ordering the parts to add a recirculation pump to my boiler! No Inkbird etc, as I have the ACE boiler with the build in digital temp control, along with switches for 900 watts and 1600 watts, or both together, so I plan to just leave the 900 watt element on whilst a recirculate the mash. I've also done things a teeny tiny bit differently. So, my shopping list (all nicely ordered, mostly from Brew Builder):- TS5 mini mag pump + psu (bit dearer than a solar, but I want to have flow control using a tap) 2 x 1/2" elbows (these will be part of the return setup I've come up with) 1/2 " xl pickup tube (actually part of the return setup again, I want to try to use it to create a whirlpool if I can) 1/2" mini ball valve - female to male (will fit on the outlet of the pump, to control flow) 2 x 1/2" female - hose barbs (1 for the pump inlet, 1 to fit on the mini ball valve on the outlet of the pump) 5 x thumb drive hose clips (for everywhere I have a hose barb, to stop it falling off) 1/2" cam & groove part C fitting (hose barb to cam & groove clamp - hose from pump outlet will attach to this) 1/2" cam & groove part F fitting (this will go into 1 of the elbows, then clamp onto the Part C, basically so I can separate the return setup from the pump etc) 1/2" BSP 40mm nipple (to attach the 1 elbow to the other elbow, creating a U shaped bend) lots of 1/2" silicone O-rings (to go in all those joints and hopefully prevent leaks, I already have plenty of plumbers PTFE tape) 1 x stainless steel vegetable steamer (from Amazon) - this will go in during the mash and the sparge, basically to stop the returning wort from disturbing the grain bed. So, no diagram as I'm naff at drawing, but the plan is:- Kettle tap - hose to pump - hose barb on pump inlet - pump - mini ball valve - hose barb on outlet side - hose to return - c&g part C fitting - c&g part F fitting - elbow 1 - BSP nipple - elbow 2 - 1/2" xp pickup tube through boiler lid into boiler, aimed to the side to try to create a whirlpool. When cooling I am going to try to aim this through the immersion chiller too, to try to mimic constant stirring. I may need to drill a hole in the lid, but kinda hoping the pickup tube will fit through the vent hole. If not, once I have the bits I'll know the size of drill bit I need to make a hole of the right size. The boiler is 48cm deep, the pickup tube is 20cm long, so the deepest it will reach will be just under half way down. I'll have to fiddle with this to find the best position. Fingers crossed for no more using a 5 litre jug to recirculate at the end of the mash..... Once I put it together I'll post a photograph. Wish me luck.
