Pumps
Saniflo Sanicondens Best Flat
Incorporating most of the same features as the Sanicondens Best, Saniflo’s more powerful Sanicondens Best Flat condensate pump offers a more compact look, a larger volume and the ability to handle multiple mechanical systems. It boosts the pH of the acidic condensate before it can be discharged into a drain line — thus preventing corrosion. The built-in tank has a capacity of 0.9 gallons, or nearly a half-gallon more than the 0.55-gallon tank in the Sanicondens Best. This larger volume maintains longer contact between the condensate and the neutralizing pellets, allowing the unit to handle fixtures with higher Btu inputs. 800-571-8191; www.saniflo.com
Stiebel Eltron WPL Series
Highly efficient cold climate air-source heat pumps, the WPL 15 A2W Premium (2-ton cooling, 25 kBtu/h heating) and WPL 25 A2W Premium (4-ton cooling, 50 kBtu/h heating) from Stiebel Eltron produce hot water for central heating, cooling, and domestic hot water production. The compact monobloc design doesn’t need refrigerant lines run during installation. The inverter-driven compressor and fan increase part-load efficiency. Superb for new construction with lower flow temperatures, supply temperatures to 149 degrees F also provide suitability for modernization projects needing higher flow temperature. Heating capacity is available at low ambient temperatures down to -4 degrees F. The heat pump achieves top tier efficiency with IPLV ratings of 15.68 (WPL 15) and 16.83 (WPL 25), 2.77 COP Cold Climate Efficiency, and meets requirements for Energy Star Emerging Technology.

Solar Thermal System
Uponor Xpress Trak
Designed for residential new construction and remodels, Xpress Trak from Uponor is a single-panel system with lightweight XPS foam at its core and laminated aluminum around the entire surface to provide exceptional heat-transfer capability.The XPS foam provides numerous benefits for both the installing contractor and the homeowner, including natural moisture resistance to eliminate caulking edges or panel grooves for increased installation efficiencies; no insulation needed in joist space below the subfloor, saving labor time and materials costs; compressive strength of 49 psi to eliminate floor deflection; lower mass for faster response times to improve system performance; and an R-value of 3.13 that allows energy use to heat the space rather than charging and storing energy into the panel. 800-321-4739; www.uponor-usa.com
Valves
Aquaguard WAGS Valve
WAGS Valves from Aquaguard can stop a leaking water heater tank from continuously refilling and dripping, or until the tank fails catastrophically. The shut-off valve halts the incoming water supply, and on gas-fired units, shuts off the gas supply to ensure the home’s safety from water heater failure. They are mechanically operated; meaning no maintenance, no electricity or no battery checks are required. They sit in a drip pan under the water heater and are activated when leaking water accumulates to a predetermined level in the pan. Once activated, the industrial-duty, one-shot safety valve shuts off the water and gas supply if so equipped. A red tab pops out to indicate valve activation. 844-438-9247; www.wagsvalve.com
Little Firefighter Gas Shutoff Valves
In regions prone to seismic activity, seismic gas shut-off valves have assumed a pivotal role in disaster prevention. Little Firefighter Gas Shutoff Valves act swiftly during earthquakes, cutting off the flow of natural gas and proving their worth in several critical ways. When the structures shake, gas lines can rupture, leading to gas leaks that spark dangerous fires. Seismic shut-off valves intervene by halting gas flow, reducing the risk of fire and protecting lives. Earthquakes can disrupt evacuation paths, making timely escape difficult. By preventing gas-related explosions and fires, these valves save lives and limit property damage, offering peace of mind to homeowners and businesses. Many quake-prone regions and insurance providers mandate their installation, ensuring compliance with essential safety standards. 714-834-0410; www.littlefirefighter.com
