So this morning I threw in a second Taco 007 pump on my system. A quick run down of the system is it leaves the back of the boiler and goes directly into the first pump, the original pump. It then goes 65' into the house and to the first appliance, 24" tubular style sidearm, then it goes into a 40 plate exchanger for on demand hot water, then it goes 45' out to our hot tub, another 24" tubular style sidearm, and then it comes back to the house and goes through the 16x20" heat exchanger in the furnace. Then back the the boiler. When nothing in the system is calling for heat I have a supply/return temp difference of 4degrees +-1.
When hooked the system up i knew little about hydronics and wanted to system to look neat and not take up much room in my furnace room since it is really small so I put in a lot of fittings. I hooked pex up more like copper. There are a total of 42 fittings in the whole system. Quite a few elbows, a few couples, and quite a few ball valves so i can bypass and isolate every part of the system for draining/maintenance. There are also a few T's in the system for hose hookups for system draining/bleeding.
I added the second pump on the return line right before it leaves the house. I did not add the pump because there was a problem. The spa is always 104, the house is always 72, and we have endless hot water 24/7 with 7 people in the house. I mainly added it as a safety measure if the primary were to fail I don't want to wake up to a frozen system when its -30 out.
Main question is does adding that second pump help with moving the water through the system? Did I gain any GPM? Just curious thanks!
