Most commercial HVAC professionals are familiar with the principles of geothermal heating and cooling. But when it’s time to put the drill to the earth, builders and engineers generally turn to a professional well driller experienced in all aspects of vertical geothermal well installation. In this blog series, we unearth the mysteries….

Except for an expansion tank and air separator, the components are often installed as a pre-piped assembly, ensuring long-term peace of mind and eliminating tedious piping work. In this blog post, we explain what these components are and the role each plays….

We are almost finished building our e-1510 pump curve! In this final blog of our series, we’ll introduce positive suction head (NPSH) to our curve and explain what NPSH is and why it matters....

This blog introduces efficiency curves (islands) to our pump curve and examines the variables impacting pump efficiency. We also introduce a valuable equation for....

In Part 2 of our How to Build a Centrifugal Pump Curve series, we added five head/capacity curves to the e-1510 4BD pump curve we are building. These curves reflect the tested performance of pumps with various-size impellers. Now, it's time to focus on the pump’s power requirement and how it....
