I am a super at a luxury coop on the upper east side of manhattan. One apartment on the ph floor was not getting sufficient cooling due to poor chill water circulation through the convector unit in the apartment. I've installed pumps before but they effected the apartments below (no control over pump speed etc.) so they were removed. This pump allows me to dial the circulation in (it has 6 settings) so as not to affect other units in the building. The plumber installed it in a few hours, and it plugs directly into a 110 volt wall outlet.

Simple, quite, and efficient are certainly all positive attributes of this pump. it would be better if it were possible to control speed via a control panel, external input, temperature control, delta-T control, or anything similar it would be a great pump. The auto mode does indeed work if you have multiple circuits connected to the pump that are opening or closing. however, if the pump is on a fixed circuit i give the auto mode low marks. picking a fixed flow or pressure gives more predictable results.

Well Worth The Money
from Andover, MN
This pump is silent, and efficient! 2-3 Gal/Mn while maintaining constant pressure and consuming 16W-18W. It moves water through 6 zone with 250' of 1/2" PEX in each zone.

So far so good
It's not heating season yet, but I have installed the Alpha. I've tested it and ran it in all of its modes. The smart mode seems to be pretty neat. It gradually ramps up when a zone valve opens until it gets to where it's happy and cruises along until the valve closes. The pump came with to gaskets and a flow check valve. Seems like a pretty nice pump.
from Long Island, NY
Put it on high to purge the lines after swapping out, then put it on autoadapt. 6watts in idle, 9-14 watts at 1gpm 1 zone. 12-16 watts at 2 gpm 2 zones. Couldnt ask for more
Alpha Pump for radiant heat
from Bryson City,NC
Had one on a 6 zone radiant floor heating system and found it was operating at the edge of its performance. It runs quietly, has options -3 speeds plus the self regulating feature which was ideal to balance the floor loops and zones. I am putting a pump in parallel to pick up a little flow when all 6 zones are on.

Great replacement for Taco 007
By Off grid user
from Upstate New York
Easily replaced 007 circulaters between isolation flanges without having to re-plumb. Much quieter. As I'm "off grid" producing my own electricity with solar and wind, I'm stingy with every watt. The Alphas use less than a third (I measured both)than the 007 with the same GPM (I measured both).Delivery was actually one day sooner than "promised". Great pump - great service - competitive price.
from White Salmon WA
These pumps are great, I use them almost exclusively now. Set it on auto and it will match most any radiant load be it one small bath or the whole house. The GPM reading on the display is also an excelent troubleshooting feature, just one glance and you know there's flow. Oh, yeah they save about 60% on power consumption. The price has been coming down also. What else can I say, they rock!

ECM circulators are the way to go
This is a good ECM circulator offering three speed control and three pressure controls as well as their auto control. The average rating is when compared to other ECM pumps, not when compared to average circulators. I would have scored the pump 5 stars if it offered temperature control or an external analog speed control.
