I've been reading into the HERMS system and the info in this topic. I'm going to touch on Matt's idea's but need some advice.
I'm thinking of using my cfc as a heat exchanger, using a central heating pump to recirculate water from my LT, and my flo pump to recirculate the runnings.
A couple of questions
The central heating pumps flow rate will far exceed the flo pumps 4ltr/min, even so, in your opionions, will this form of heat exchange be efficient enough?
As the liquor in the LT will be used for sparging, will it be safe to use a CH pump?
Would it be better to use a coil of copper in the LT and run the wort directly through that, therefore only using the pump I already have?
I'm not sure I'm too keen on this idea. I'm worried the copper in the LT will impart a flavour to the liquor.
I don't have any space for a rigid set up at the mo but spurred on by seveneer I would like to come to a compromise.
If I can attach the CH pump to the other side of the cfc above I will have a compact unit which I can store easily and bring out as needed.
Can anyone see any problems with this idea.
Cheers
