I have mentionedy temps before and got lots of good feedback, so today I measured my run I could not find any info on how to select a pump, I have a Taco 007 my run is 112' with (3) 90 angles and (1) 45 on both the return and the feed so the total is (6) 90 and (2) 45, 14 feet of that is in the house which is plain 1" pex with neoprene pipe insulation, the run outside is the 1" CB insulated pex, I am going to try and buy a meter today to confirm my temps but my outdoor boiler is at 188, my indoor unit is at 170 and the return outside is at 155-160, there is a section of CB pipe that is only 1' deep for about 4' now that I have a backhoe I am gonna dig it up this summer and put it deeper I could probably get rid of a 90 that way to.

What is the purpose of going deeper? Chances are that will only decrease your efficiency.
I can't beleive how many folks are running 007's
We're you using hot water and pulling heat when you tested temp drops?

Ayuh,... Really,... I went with Grundfos 3 speed units, All through-out my systems...

It depends on the conditions. Around here most places the ground is dry as deep as you want to dig. By going down to where the ground is 50 degrees instead of 10 degrees it will cut the temperature differential down 40 degrees. With a lower differential there will be less heat loss (assuming same soil and moisture)
Also, if you are in the frost and it is shifting around, I can't imaging that being good for frozen plastic.
-
Is the 112' each way or round trip?
I would change to a Grundfos 15-58. It will use about the same amount of power but move more water. The standard model has the flanges rotated 90 degrees from the Taco 007. If that won't work the way your pump is currently mounted you would want to get the rotated flange model.

running a 007 here as well
-
Yea going deeper as long as your soil allows that, in my area that isn't a possibility at all. You get into pure muck down around 3ft most of the time, but areas are different
-
Switched from a 007 to a OOR 3speed to get more flow on my system. A OOR is the same as the 007 on low and close to an 009 or so I high I think.
-
009 is another strange one we see, it's a low flow but high head pressure pump....
The 011 is a pump I feel is a good choice in a lot of situations
-
It seems to me that everyone that I know personally runs either a 007, 009, 011

I forgot about that pump. It has almost the exact same flow rate as a Grundfos 15-58.
It will do more GPM than an 009 unless you have a fairly restrictive system. Then an 009 will move more.
-
What is the difference ? 009 007 ?? I run a 009. Just because that what was installed.
-
A 009 is a very high head pressure low GPM pump and a 007 is a real low head pressure higher GPM pump.
Unless you have real short lines or go bigger than 1" the 007 won't move enough water to work properly.
The 009 can handle a lot more pipe and plate, etc so it doesn't make as much difference adding more restriction to line but it can only barely do enough for most houses.
-
Most dealers n customers to just assume 007 is ok, 009 a little better, 011 a little better
-
Only have about a 30 ft run to house with pex with two 90s till it gets to the DHW and heat exchanger, and then the normal I quess set up.
-
I run a 3 speed broeder pump on high with no issues. I have ran low and medium and it was fine but when a shower and heat was on the blower would run a little longer. I keep it on high more or less to keep all the water a average mixing temp instead of bringing back too cool of water. I have a spare cartridge for this pump but after I use that cartridge I am going with the armstrong e9. Scott7m don't you think the broeder is a workhorse pump?? Ha
-
Buddy there good when there working lol
You'll hear it start to rattle one day and know its time, you may get a good life out of it though
They are an electric hog though, I think the last time I checked a broeder it was like 280 watts
That Armstrong e9 would do the same work on 115 watts

That sounds like a very bad setup for a 009. What kind of heat exchanger do you have for the DHW?
I believe CB says not to use the 009 on a run that short.
-
I have a side arm for DHW

I haven't been able to find where I saw CB said not to use the 009 on a short run.
If you want to stay with taco I would switch over to a 00R, 008 or 007. The 00R would be the best of the 3 and the 007 the worst choice.
If you want to spend a little more money but get a much better pump, the Alpha should work really well there and use a fraction of the power.
-
The alpha would pay for itself in time, The alphai is something I will likely put on my own system next year.
-
I got a temp gun and my temps are problay not as bad as the indoor boiler meter would have me believe the temp meter has everything with 10 degrees but my pump is rattling so I will have to pick out a new one
-
i also run an 0011 but with the new pumps out today you might talk to rsi or scott or yonderheating (all knowledgable dealer i think) and they could direct you to (maybe) a three speed pump that would maybe give you a cheaper pump to operate (on a lower speed) and then you have the option of upping the speed (gpm) if you add on to your system later.
in the past few years these small pumps have come a long way and there are many different choices to be had now?
