Aquatherm’s latest offering is a thinner version of its 4” blue pipe. It delivers roughly a 20 percent higher flow volume than SDR 11, but at a lower cost and 35 percent less weight. Appropriate for hydronics, geothermal systems, cooling, air compression and industrial applications, Blue Pipe boasts advantages over PVC and other piping alternatives: it’s lightweight, non-corrosive, durable and fully recyclable. All Aquatherm pipe is made from Fusiolen polypropylene, a chemically stable compound that won’t leach into water.

The average family of four can save 17,000 gallons of water a year—up to 46 gallons a day—by installing one ACT-E1 under their sink. Designed with a highly efficient, electronically commutated, permanent magnet motor, this lead-free pump uses one third the power of a standard circulating pump, and is available in fixed and adjustable thermostat versions. An adjustable timer can also be programmed, so the pump runs only when hot water is most frequently required.
