Flow rate of a Taco 007 vs 008?
Could someone tell me the standard flow rate for a Taco 007 and a 008? I have installed the 007 on my radiant heat loops which are between 300 and 1200 feet (6 zones) and used a 008 for the heat exchanger. I am much more at home with baseboard and/or radiators where flow is less critical. Seems though a few of the zones are returning water fairly hot - water out at 120-130 and returning at 100 compared to my poured floor zones out at 140 return at 90-100.Should I slow the flow down in some zones via the ball valves? Zones are heating fine I was just wondering if I was wasting energy by not getting more out of the water temp.
