CircuitSolver, a ThermOmegaTech brand, announced its CircuitSolver Cold Water Balancing Valve (CSU-CW). The CSU-CW is a dynamic valve designed to automatically balance cold water recirculation systems utilizing the same reliable and precise thermal actuator technology as the original CircuitSolver for balancing recirculating hot water systems, the company says. The valve will effectively mitigate the risk of Legionella bacteria growth in a domestic cold-water system (DCWS) by continuously monitoring water temperatures and modulating flow to maintain a set temperature at the end of each branch or riser, the company adds.

Mitsubishi Electric Trane HVAC US announces Heat2O, an all-electric domestic hot water heating system designed to improve sustainability and reduce energy consumption in multifamily buildings and large-scale commercial facilities. The Heat2O heat pump water heater (QAHV-N136TAU-HPB(-BS)) reduces the environmental impact of DHW through energy-efficient operation while using CO2, a natural and environmentally friendly refrigerant with a global warming potential (GWP) of one and an ozone depletion potential (ODP) of zero, the company notes.
