Taco Metals 007E-2F4 ECM High Efficiency Circulator Pump 120V/60Hz/1Ph - Cast Iron, Universal Flange

Quiet easy replace over the old taco 300

I recently installed the Taco Water Circulator M007 in my home heating system, and the performance has exceeded expectations. This circulator is not only efficient and quiet, but it’s also clearly designed with longevity and real-world use in mind. One of the standout features is its energy efficiency. The M007 uses just the right amount of power to maintain strong, consistent water circulation without unnecessary energy consumption. My heating system runs more evenly now, and I’ve noticed a reduction in overall energy usage — a win for both comfort and the utility bill. Another critical benefit is its built-in protection against dry running and air pockets. The M007 is smartly engineered to avoid the common issue of pumps burning out when there’s a lack of water or trapped air in the system. It handles these situations gracefully, ensuring the pump remains protected. Even better, the circulator has the capability to move air pockets toward the air separator, allowing them to be safely vented out of the system. This feature alone saves a lot of time and hassle in bleeding radiators manually and helps maintain optimal performance throughout the system. In terms of reliability and peace of mind, the Taco M007 delivers. It’s a strong, capable pump that you can install and trust to do its job day in and day out, even in demanding conditions. Highly recommended for anyone upgrading or maintaining a hydronic heating system — it’s an investment in both performance and durability.

Replaced failed unit that was three years old. Hope this one lasts longer.

Very quiet and it can detect air or debris in system.

Replaced an aging pump AND obsoleted a faulty flow control valve with this all-in-one. The IFC is in the box, optional if you want to use it or not. Make sure your installation flanges are clean of rubber from the old O rings, mine had old rubber stuck that I carefully razor bladed off, and you must have knowledge about de-pressurizing a heating system, new pump priming, basic electrics, etc. Plenty of vids on youtube. I am going to get two more and pop them in when the weather breaks. Power to the people!
