Hi Guys,
I've picked up an "instantaneous" hot water system that I want to use as a replacement for my HLT. Why? Simple - I don't need to get another 200l drum (for a HLT for big brew days); no more having to wait for an hour or more for water to reach strike temp; sparge water when I want it; & no hassles with logistics when doing big brew days (ever waited on 150+L to heat up in order to sparge?)! It even opens up the possibility of moving to fly sparging instead of batch sparging large batches.
Anyway, back to the unit. It's an older manual Bosch unit (ie no computer controllers) which runs on natural gas (NG). To obtain my desired temp, it should (hopefully) be a matter of simply adjusting the flame & flow rates (in/out/hot/cold). It has a flame adjust as well as a hot & cold "tap" which I think are on the output (I think the unit was used for a shower).
Now to the questions:
- I understand that LPG uses a smaller "jet" size than NG, but how do I determine what size I need to convert to LPG? where can I get them?
- Do I need to run a regulator off the LPG bottle? If so what sort of flow rate is likely to be required? Would an adjustable high pressure reg provide any benefit?
- Do I need a licensed gas fitter to do this sort of work?
- Can anyone recommend where I can obtain reasonably priced inline thermometers & flow meters?
Has anyone done this before?
Any licensed gasfitters in sydney (inner west) care to help out or can you recommend someone licensed to help out in return for a few brews?
