The Tank Booster is a cost effective solution for increasing usable hot water capacity on an existing tank or a new high efficiency water heater. Adding a Tank Booster
mixing valve to a water heater allows water to be stored at a higher temperature, but safely delivered at 120°F (49°C) to all outlets. The valve mixes both hot and cold water, which increases the tank’s water capacity. It also reduces the chances of legionella growth by allowing the thermostat to be set at 140°F.
