Great pump, horrible packaging

By Plumber Dave

from P'ville NY

Verified Buyer

Comments about ALPHA 15-55 F Cast Iron Circulator Pump w/ Terminal Box:

Only negative, is the poor packaging the manufacture chooses to use.
Heavey pump packaged with a small plastic check valve that both tumble around an oversized un-dampened box.

Very nice circ pump

Comments about ALPHA 15-55 F Cast Iron Circulator Pump w/ Terminal Box:

Replaced a "green" pump that just wasn't doing the job. This Grundfos was super easy to install. Nice European-style touches (like not having to futz with wire nuts). This pump is quiet. Maintains proper temperature differential.

Silent energy savers

Comments about ALPHA 15-55 F Cast Iron Circulator Pump w/ Terminal Box:

Bought three of the alpha pumps and set on auto adapt. Main loop circulator is running constant 24 watts and pumping 12 Gpm One zone on auto runs 14 watts @10 gpm and last one running 13 gpm and 21watts. If you are looking for a low energy consumption pump this is the one.

Dramatic energy savings

By Sawmill Dan

from Fairlee, VT

Verified Buyer

Comments about ALPHA 15-55 F Cast Iron Circulator Pump w/ Terminal Box:

I replaced 5 Taco 007 pumps with these Alpha 15-55 pumps in an off-grid system.Three pumps are set at low constant speed, one is at medium constant speed and one on automatic due to different requirements.The total electrical draw of all five pumps is less than one of the 007's. One pump supplies a radiant system in a 1500 square foot shop and draws only 6 watts! The ability to adjust the flow rate makes balancing the system easy and the cool digital readout is the best. These pumps are also completely silent.

great pump

Comments about ALPHA 15-55 F Cast Iron Circulator Pump w/ Terminal Box:

Installed two Alphas to replace two Taco 007-IFC zone circulators in a constant-circulation space heating system. The Alphas are running on low fixed speed (i.e., not using the Autoadapt feature because as zone circulators the head and flow are fixed in each zone). The system deltaT is better now; the system was previously overpumped. The Alphas are silent. The electrical draw of this system dropped to 12 Watts with the Alphas from 163 Watts with the old circulators. That is a 93% reduction and will result in huge seasonal electrical savings for the building.

The build quality and overall design of the circulators is excellent. The wiring could not be easier. The simple lighted "user interface" and push-button mode-selector is just that -- simple. Well laid out and works great.

Works Great and easy to install

By HeatingSystemIsMyHobbie

Comments about ALPHA 15-55 F Cast Iron Circulator Pump w/ Terminal Box:

[...]When first powering up, be sure the system is pressurized or pump will show 0 gallons/per min flow regardless of setting. Instructions say nothing about this. Otherwise great product.Have it connected to a wood stove water heating loop and a TurboMax 65 tank (see my Turbomax review also). Set on AUTO, it draws about 24 watts when the system is cold, as the system heats and the pressure increased to 15PSI, power drops to about 21 watts. About the same power needed wether circulating only to the storage tank or baseboards and storage tank. I expected more power would be needed when running thru the baseboards also, but not true??Anyway, great product and so far has been working flawlessly.

  • ALPHA 15-55 F Cast Iron Circulator Pump w/ Terminal Box

    Q:

    Will this pump be equivalent to a TACO 009-F5?
    Asked on 1/2/2012 by Ridgekid from Homer City, Pa

      A:

      Not really: the Taco 009 has higher head pressure capabilities, but lower flow ratings. You need a circulator that can handle both the flow rate and head pressure of your system.
