We Offer Quality Geothermal Supply Products & More than 2 Decades of Geothermal Experience to Help You Complete the Job!

Geothermal Flow Centers, HDPE Pipe, Fittings, Manifolds, Pipe Insulation, Tools & More!

Geo-Hydro Supply, Ltd. is proud to supply a wide variety of geothermal supply products for residential and light commercial applications. We supply the original non-pressurized flow centers and flow center accessories, brass fittings & adapters, compression fittings, socket fusion fittings, HDPE pipe, manifolds, pipe insulation, and geothermal installation tools. Serving the 48 contiguous states we stock materials from top names in the industry such as B & D Mfg, Inc., Geo-Flo Products Corp, Centennial Plastics, Central Plastics, Grundfos, K-Flex, Armacell, Nupi, Merril Manufacturing, and Ideal.

Drawing from more than two decades of experience in the geothermal closed-loop industry, we recognize differences in product quality and only stock those to which we have the utmost confidence. One such product is Centennial Plastics. This polyethylene geothermal tubing is one of the best in the industry in quality, consistency, and reliability, and comes with a Centennial Plastics 50 year warranty. We stock socket geothermal fusion tees, couplings, elbows, and short headers along with many other heat fusion fittings supplied in a variety of sizes at competetive prices.

We are proud to offer patented non-pressurized B & D MFG flow centers. You can expect exceptional quality from our geothermal flow centers manufactured with Grundfos pumps. These units minimize flushing time and remove air from the loop as they operate. The QT Flow Center, which is housed in an attractive white insulated cabinet, is one of the greatest things to happen to the geoexchange industry from the company who started it all. We also supply B & D flow center products, such as pumps, hose kits, brass fittings, valves, adaptors, flow meters, pressures gauges, hydrometers, fusion tools, and accessories.

You will find our most popular stock items available on-line, but we have a full line of other geothermal supply products to meet your commercial and residential needs. Feel free to brouse our site and buy with confidence.
