I would like to add just enough storage to help eliminate my idle times and help increase my boiler temperatures when I come home from the 12 hour work day away from the boiler. I'm thinking a vertical air compressor tank of 60 -80 gallons would be perfect for that time period.
My question is this. I run series piping from the boiler though a DHW sidearm to the furnace water to air HX and then back to the boiler. So I have a 6' or so vertical run from the exit of the DHW sidearm to the water to air HX. If I would replace that vertical run with the 60 or 80 gallon tank how much would the pump head increase? Instead of pumping through a 1" pipe I would be pumping through the vertical storage tank so to speak. My flow rate is around 5.5 - 5.75 GPM and I don't want to lose too much more GPM. Would the flow stay the same?
Also, is a bottom to top feed through the vertical storage tank recommended?
Thanks for any input.
