Save energy and water with a compact single point of use storage water heater Made in Germany the STIEBEL ELTRON SNU 5 and SNU 10 under sink open vented water heaters deliver hot water quickly to a single sink. These point of use water heaters eliminate long runs of pipework for isolated sinks and reduce the waiting time for hot water to arrive at the outlet. They are conveniently installed directly underneath the sink and must be fitted with specialised open vented tapware. The open vented tapware acts like a relief valve which is normally found on a storage hot water tank, instead the SNU’s sink mixer relieves pressure from the tank. The SNU hot water system incorporates a highly efficient insulation design which provides thermal insulation and minimal energy losses. The thermal cut-out provides a permanently safe maximum water temperature. In addition, the SNU has a Thermo-Stop function that helps to save energy and prevents the mixer tap from being heated in stand-by mode. These features, coupled with a range of tapware specifically designed to complement the brilliant SNU point of use heaters, ensure that we have the ideal solution for your kitchen, tea preparation area, kitchenette or BBQ area. Drip-Stop design on the SNU 5 open vented water heater The SNU 5 incorporates a Drip-Stop design that eliminates dripping from the tap during heat up due to its specialised construction that helps save water.
