Glycol heat loss

How much efficiency is lost by putting 30% glycol through a boiler like a Triangle Tube Prestige? I understand glycol is inferior at heat transfer. After lots of googling all I found was that you may need more feet per second through the exchanger.

30% glycol
Has roughly 93.5% of the specific heat that pure water does, so you need to pump about 7% more volume in order to transfer the same amount of BTUs.0 -
7% more than minumum flow?
So there's really no efficiency lost as long as you pump more water through the boiler? The 399k boiler has a minimum flow of 19 gpm at full fire so is this the number i need to use?0 -
minimum flow
Would be 7% higher as well, so your 19 GPM becomes 20.3 GPM. Is this piped with a hydraulic separator or closely spaced tees in a primary-secondary configuration? If so (and assuming you don't have overly restrictive piping in that loop) you can usually use a 0010 or a Series 100 with the 399.0
