The Water Heater Tank Booster Pro The Tank Booster is a simple to install thermostatic mixing valve that distributes controlled temperature water through hot water systems in residential and commercial applications. The high quality valve mixes hot water with cold to deliver tempered water at a controlled temperature to 120F. By storing water at higher temperatures in the hot water heater usable hot water output can be doubled. Storing water at higher temperatures reduces risk of legionella bacteria growth which thrives in water stored at 95-115F. In the event of a cold water supply failure the valve will shut-off to protect against scalding. Designed for easy and quick installation, the Tank Booster is shipped complete with thermostatic mixing valve, flexible connector and water heater tee. Benefits and Features Precise temperature control. Safer hot water from all outlets. Allows the water heater to be set at 140F (60C) or higher to prevent bacteria growth while delivering water at a safe 120F (49C) and doubling usable hot water output. Adjustable and lockable mechanism minimizes unauthorized tampering with factory valve setting of a maximum 120F (49C). Recirculation port with plug decreases potential heat loss. Can be used with SharkBite flexible water heater connectors for easy installation on Copper, PEX, or CPVC pipe.
