Title: circ pump placement
Post by: kj5036 on July 27, 2012, 05:00:27 PM

Planing my install and would like to put pump in basement but noticed everyone has them on the boiler. Would it be ok in the basement?

I currently have one inside my house with no problems. It seems like it would be easier to prime on the furnace but I have not figured out any other benefit to having it on the furnace. That said, I do plan to move mine there this summer. I don't really remember my reasoning, only that that's the way I mapped it out in my head. I will be interested to see other input on this one.

 It is easier to prime on the furnace. The main thing is to not place the pump at the highest place in the system. Because these systems are open systems there is always the possibility of having some air introduced. If you air lock your pump it will not last very long. Normally if you purge your lines really well using your domestic water pressure you will have no issues. I have seen guys replace several pumps in a matter of a week because they never got all the air out of the water lines and the pumps would loose prime.

OK cool. Is there any special method of making sure the lines are purged good?

I put mine in my basement. I like it and it works well for me. When I installed it I put a t in the pex just before the pump and put a hose connection on the t. It made it easy for me to hook a hose from my sink and fill it. I also put a switch next to it so I can turn it on in the summer once in a while.

Think im gonna go with the B&G NRF-22 for a pump. My run is only 67' from boiler to furnace and then through a 10 plate exchanger right after. Anyone have experiance with this pump?

That pump might be a little too small with a 10 plate. If you use a 20 plate instead then it would probably be fine.

I ended up loacting the pump in the house, cause if I ever have to replace it (especially during the heating season) :o, I do not want to be sitting in a snowbank replacing a pump.
