Tank Booster™ Thermostatic Mixing Valve

The Cash Acme hot water Tank Booster™ combines a Thermostatic Mixing Valve (TMV), Flexible Connector and Water Heater Tee in one package. It’s designed to effectively double a household’s usable hot water heater capacity while delivering water at safe temperatures in both residential and commercial applications.
Tank Booster provides source-point temperature control for hot water heaters, allowing the water in the tank to reach up to 140°F – high enough to destroy bacteria. While the water within the tank is incredibly hot, the Tank Booster outputs are all set at 120°F (49°C). This ensures the water leaving the tank is delivered at a safe temperature. The valves can be easily adjusted if a lower temperature is desired at delivery.
Tank Booster products are shipped with the valve, flexible connector and water heater tee. They are compatible with SharkBite Flexible Water Heater Connectors & Ball Valves for easy installation in systems using copper, CPVC or PEX tubing. There’s no need for additional transition fittings.
