Mixing down water temperatures
Hey Guys, It has been bugging me to find out about mixing down hot water of about 55 deg c to 35 deg c and what losses there would be in doing that.
In my thinking i would say it would be minimal as you are using less hot water when you are mixing it down but i was wondering if it was less efficient to do so.
I know it would be better to only produce the water in a hydronic circuit to 35 deg c and use that for the under floor loop but if you had a mixed circuit with high temperature radiators and underfloor on the one circuit.
Another thing that could be done is to pass it through the radiators first to reduce the temp of the water through dissipation and not mixing it down, this would be better but then both circuits will have to be in series.
Does anyone know of the losses incurred when mixing down water?
I look forward to your comments.
