Here are four major benefits of ECM circulators and why they are fast becoming the energy-efficient pump of choice.

System COP is a more relevant metric of geothermal heat pump performance since the owner is paying for the electrical energy to operate the heat pump and the circulator, and their operation is always simultaneous.

The goal is to keep the system COP as high a possible as the operating conditions of the heat pump change. The logic behind maximum COP tracking is to continually look for an earth loop flow rate that improves the system COP.

Every year, manufacturers develop new or improved products for the North American hydronic market. Product development planning by those manufacturers depends on several factors. Here are a few of the main considerations.

Taco Comfort Solutions has expanded its family of easy-to-use, high-efficiency ECM circulators with the addition of the 0026e.

When designing hydronic circuits, most engineers focus on what’s necessary for that circuit to absorb thermal energy at a heat source, carry it along like a conveyor belt and drop it off at one or more heat emitters.

 If you’re anything like me, the first thing that comes to mind when you think about variable speed circulators is 1970s rock band Supertramp.

I was first introduced to black water in 1972 as an apprentice at F. W. Behler, where I had just begun the never-ending learning curve. We were draining a hydronic hot water system that served a large row home with standing cast iron radiators. The water was dark colored and smelled a bit funky, but it was explained, to me, that this was perfectly normal and highly desirable because that indicated the hydronic water was essentially devoid of free oxygen.

I read somewhere that the most prevalent machine in the world is the electric motor. I thought about that for a while and it made sense. Just look around. But then I began to wonder what the second-most prevalent machine in the world is. Turns out it’s the pump!
