Thanks or the tech info, will try and reduce file size next time, still learning.
A brief explanation is in order. The HLT is a 30l, 2400w hot water urn with ball valve and quickconnect to mash tun. The "rubbish bin" is actually the mash tun, its a drinking water cooler. galv outer shell, insulated wall and SS inner inner shell.
It had a rainwater tank tap fitted which was replaced with a ball valve connected to SS braided hose for lautering, (I think the yanks refer to this as a bazooka) the long quickconnect is used to drain into the SS keg kettle through another ball valve and a 3 ring burner with low pressure reg to boil it up. I am confirmed batch sparger and regularly reach over 85% eff with this set up. Cooling is by the worlds ugliest immersion chiller, you may also be able to see the hop basket sitting inside it, termimesh and a flour sifter. There you have it.
