Can TapBoost be used in an unvented system?

TapBoost can be used in an unvented system however, it should only be fitted to a cold-water outlet as it cannot be installed on hot water pipes/outlets from an unvented system. Please note, TapBoost requires a natural flow of 1.2 L/min from any outlet to activate. The hot water supply from an unvented system can be improved by boosting the cold mains into the cylinder, this can be achieved by installing a TankBoost.
