I built one of those mash tuns with a sparge arm fitted into the lid,worked perfectly. What you do need is to know how much hot liquer is flowing from your HLT into the sparge to balance what your drawing off from the mash tun.

Thats good to know. Usually for sparging I only add the exact amount of water needed to my HLT so when my HLT hose runs dry Ive added the correct amount. Is this method okay?

[Ciderhead]

yeah but at what rate  my sparge takes 50-60 mins and I need to regulate the flow into and out of the mash to do that, put a camera in there

[Hop Bomb]

I can look in anytime & adjust flow out of both HLT & mash with the taps. Ive a gopro camera here but it would fog up in the mash tun

[DEMPSEY]

Whatever way works for you. What I used to do is have plenty of water in the HLT and have a sight glass to check what is already in the HLT then open the valve and let the water flow until I transferred what I needed.

Dumping it all in in a couple of mins is batch not fly

Kinda but me flow rate in sort of matched me flow rate out.

Fair point and I know when you get to a certain age thats easy to gauge

Hi Hop Bomb,

Probably you could get away with a smaller element as you said you won't be heating the water to boiling point. However a smaller element will take longer to heat the water. Don't underestimate the amount of time taken to get a large amount of water up to 75C. While I could use the 5.5kw for a boiler, without some kind of relay to control it, I felt that it would be too powerful.

I like the idea of being able to heat water for both the strike water for soaking the grain in the mashtun and also for cleaning up afterwards.

2 x 2.2 KW kettle elements will work on standard mains, use both to get there, one to maintain, if one fries you always have a backup

Cheers lads.
