Description

The Taco 0034eP-F2 (0034ePlus) represents the pinnacle of modern hydronic pumping technology. This high-performance, variable-speed circulator utilizes advanced ECM (Electronically Commutated Motor) permanent magnet technology to deliver unparalleled energy savings and precise flow control. Designed as a direct, drop-in replacement for a wide range of older, inefficient pumps, the Taco 0034eP-F2 is the ultimate solution for upgrading large residential and light commercial hydronic heating, chilled water cooling, and domestic hot water recirculation systems.

Its standout feature is an intuitive digital user interface that allows for precise adjustment, making it easier than ever to fine-tune system performance while reducing power consumption by up to 85% compared to standard AC pumps.

Key Feature Breakdown

  • BIO Barrier®: An integrated, cleanable filter that protects the pump’s internal components from system debris and contaminants, preventing clogging and ensuring longevity.

  • SureStart®: An automatic sequence that activates on startup to unblock the impeller and purge air, ensuring reliable operation every time and preventing air-lock.

  • Nut-Grabber Flanges: Flanges are designed with features that hold the nuts in place, allowing for one-person installation and dramatically simplifying fit-up.

  • Dual Knockouts & Removable Terminal Strip: Provides wiring flexibility for conduit from either side and allows for easy connection on a workbench before mounting the pump.

Frequently Asked Questions (FAQ)

Q1: What is the difference between the 0034e and the 0034eP-F2 (0034ePlus)?
A: The standard 0034e comes with a simple dial for speed control. The 0034eP-F2 (0034ePlus) features a advanced digital interface that provides more precise control and system feedback.

Q2: Can this pump really replace my old Taco 0011 or 0012?
A: Yes, absolutely. The 0034e series is engineered as a direct hydraulic replacement for these popular models and many others. Its performance curve covers the range of all listed pumps (009-0014), making it an incredibly versatile upgrade.

Q3: How does it save 85% on energy?
A: ECM technology allows the motor to only use the exact amount of power needed to achieve the set speed and flow. Traditional AC motors run at a fixed, high speed and use resistors to “slow down,” which wastes massive amounts of energy as heat. ECM motors adjust their torque electronically with minimal energy loss.

Q4: Do I need a special control to use this pump?
A: For continuous circulation (e.g., constant hot water recirc), you use the pump’s built-in controls. For zoned heating applications where the pump should only run on a call for heat, you must use it with an external Taco ZVC (Zone Valve Control) or SR (Switching Relay). The ZVC/SR provides the on/off signal.

Q5: Is the pump self-priming?
A: While it features SureStart® to automatically purge air and unblock the impeller on startup, it is not self-priming in the traditional sense. It is a wet-rotor circulator and must be installed in a location where it will remain flooded with water.

Q6: What is the warranty?
A: Taco typically offers a limited 3-year warranty on the 00e-series circulators for residential use. Always confirm the specific warranty terms with your supplier.


Pros and Cons

Pros:

  • Massive Energy Savings: Reduces operating costs by up to 85%, offering a strong return on investment.

  • One-Pump-Fits-Many: Replaces a huge inventory of legacy pumps, simplifying sourcing and upgrades.

  • Whisper-Quiet Operation: Double-insulated and ECM-driven for exceptionally low noise levels.

  • Superior Protection: BIO Barrier® filter and SureStart® feature prevent common causes of pump failure.

  • Easy Installation & Wiring: Nut-grabber flanges, rotatable housing, and dual knockouts save significant time and labor.

  • Precise Control: Digital interface allows for perfect fine-tuning of system flow rates.

Cons:

  • Higher Initial Cost: Significantly more expensive upfront than a standard replacement circulator.

  • Requires External Control for Zoning: An additional ZVC or SR module is needed for on/off operation in zoned systems, adding to the total project cost.

  • Electronics Sensitivity: While robust, the internal electronics can be more susceptible to damage from power surges than a simple PSC motor, making a surge protector a recommended addition.


Conclusion & Best Applications

The Taco 0034eP-F2 is not merely a pump; it’s a strategic upgrade for any hydronic system. It is the ideal choice for homeowners and HVAC professionals looking to reduce energy bills, eliminate noise, and future-proof a heating or cooling system.

You should choose this pump if:

  • You are replacing an old, inefficient Taco 0011, 0012, 0013, or similar.

  • Your goal is to significantly lower electricity bills and your system’s carbon footprint.

  • You need a quiet, reliable pump for a living space near a mechanical room.

  • You value easy installation features and built-in system protection.

For the ultimate in efficiency, control, and modern performance, the Taco 0034ePlus digital circulator is a top-tier investment.

Disclaimer: Proper installation is critical for performance and warranty. It is recommended that this product be installed by a qualified HVAC professional.
