4647Features. Boost uses a venturi cartridge to give power shower performance on gravity hot water systems without the need to fit a pump . Designed to work where there is low pressure, tank fed hot water and high pressure mains fed cold water. High pressure mains cold water "pulls" tank pressure cold water through the venturi valve inside the shower with the mixed water coming out at a much greater rate than could be achieved using an electric shower or ordinary shower mixer valve. Gives excellent showering performance in conditions that are often deemed unsuitable for conventional thermostatic showers, including guest rooms, en-suites and attic bathrooms.'Set and leave' controls . Automatic safety shutdown in the event of hot or cold water supply failure . Recommended for applications where the hot water pressure is between negative 0.05 bar and positive 0.3 bar pressure. Cold water mains pressure can vary between 1.5 bar and 3.0 bar . A dependable alternative to an electric shower, which are notoriously unreliable and have a short life expectancy due to scale forming on the heating element. 5 year guarantee Boost optionsBoost built-in shower packOrder code A5700AAPack comprises - Boost built-in venturimixer valve with Idealrain M1 shower kit.Boost exposed shower packOrder code A5699AAPack comprises - Boost exposed venturimixer valve with Idealrain M1 shower kit.Boost built-in fixed head shower pack Order code A5701AAPack comprises - Boost built-in venturimixer valve with Idealrain S1 rainshowerwith 300mm horizontal arm.Trevi Boost exposed packInnovative and practical this shower valve boosts water flow in low pressureareas.
