I have 2 hoses I'll sell you. Used 12ft 1/2" with 1/2" quick disconnects. I went electric and dont need them. How about $40 for both + shipping. I also have 48" stainless 1/2" gas connectors with natural gas orfices with valves.
I broke my pyrex sight glass even before using it. I found some 6 ft polycarbonate tubing on amazon that was the exact same dimensions for cheap. Just cut to length and you'll have some spares. It works great. https://www.amazon.com/gp/product/B000OM9JPG/?tag=skimlinks_replacement-20
For 1 bbl batches using eherms, I am 2-3 degrees hotter in the hlt compared to the mash tun thermowell. I have my pump valves fully open. It does take a bit for the temp to normalize - probably 15 minutes.
Just sharing some pictures and info on a new eHERMS HLT I ordered from Brewers Hardware. The tank is 45 gallons, has (2) rear 1.5" TC element ports, 1/2" TC sight glass ports, 1.5" TC feed through HERMS coil ports, and 1.5" TC ports for the thermometer and drain. The tank is skirted and drains...
Go to a hardware store and get a double gang deep box, (2) 30 amp commercial light switches, and wire up an input and 2 outputs. This is what i did but for 50a input. You can do the same thing with 30a input but dont turn on both elements at the same time.
