Therm-Omega-Tech introduces its Circuit Solver valve for domestic hot water systems. The stainless-steel valve has received NSF/ANSI 61 and California Lead Plumbing Law (AB1953) certifications from IAPMO. This is the first of its kind for a self-actuating temperature control valve used for balancing domestic hot water systems. It eliminates the need for oversized recirculating pumps, minimizes heat loss by reducing fluctuations in average temperature and flow rate and lowers flow in hot water return lines. Therm-Omega-Tech
