Leaders in Geothermal Technology

Geothermal technology is an investment for homeowners.  The Non-Pressurized Flow Center offers the best reliability and function available. Low loop pressure is avoided with its non-pressurized design and it is backed with a multi-year warranty. Our product is made in the USA with only the best parts and materials available, making it a smart choice for your investment.


The Non-Pressurized Flow Centers are available with high quality Grundfos Wet Circulator pumps in either B&D MFG Grundfos 26-116 or Grundfos 26-99 making it easy to fit your specific needs.

Installation is Simple

Installation is easy with the Non-Pressurized Flow Center. Just connect the return line from an earth loop to a swivel connector on top of the flow centers. Then install the supply line from the flow center to the ground source heat pump unit using a flow center hose kit. You are even able to purge your earth loop with the Non-Pressurized B&D MFG flow center using valved manifolds installed in the home.

Easy to Use and Maintain

Even if the canister runs low, a built-in check valve will hold water in the pump(s). A self-sealing system keeps the water in and dirt and debris out. This results in a trouble-free operation, easier installation and fewer service calls. To check or add antifreeze, just remove the self-sealing lid to be able to add fluid or check levels. A Flow Meter Tool can be used to check flow rates at the flow center. With the pumps being the only moving part of the system, service is minimal and simple to perform without risking fluid loss or air entering the system.

Our online store is open 24 hours a day 7 days a week making it simple to order by internet. Our office is open from 7:30-4:30 ET with an expert staff ready to assist you with your purchase.
