Venturi Shower
A venturi shower contains a special shower valve that offers high flow rates without having to use a pump or power shower.
Features of the Venturi Shower include
- high rates of flow
- good pressure
- no electrical connections
- plumbs straight in
- push fit connections
- economical
- low maintenance
Venturi showers are a relatively cheap and easy to install, for bathrooms with gravity fed hot water systems and mains pressure cold water.
Venturi showers will not operate with high pressure hot water systems such as combination boilers or unvented systems.
How They Work
High pressure mains cold water is used to "suck" tank pressure hot water through the special venturi valve inside the unit, so that the resulting mixed water comes out at a much greater rate than could be achieved using an electric shower or ordinary shower mixer valve. The venturi shower uses no electrical connections, it simply plumbs straight into the heating system.
There must be a 300mm gap between the top of the shower head and the bottom of the supply tank (click diagram to expand).
Venturi showers will only work where there is low pressure, tank-fed hot water and high pressure, mains-fed cold water - an arrangement which is commonly found in UK homes.
Shower manufacturers making this type of venturi unit include New Team. Venturi showers were also previously made by Aquadart and Croydex but their popular
