    Overview

    Having a reliable hot water system means you can enjoy uninterrupted hot showers and get on with your cleaning chores more efficiently. The Stiebel Eltron DEL 18 PLUS Electric Hot Water System provides instantaneous hot water supply that doesn’t involve large tanks and heat-up wait times.

    You only need to turn on the hot water tap and the efficient system will turn on automatically. Once you close the tap, the system automatically turns off so you can reduce energy consumption. You can adjust your hot water system to better suit the needs of your household. You can select hot water temperatures between 20°C to 50°C in 0.5°C increments so you can have precisely heated water for your comfort and convenience.

    The shock of an unexpected cold shower is a thing of the past with this instantaneous electric hot water system from Stiebel Eltron.
    Efficient and instantaneous hot water supply

    This hot water system can supply hot water to several draw-off points so family members can use showers and kitchen sinks simultaneously. The system only turns on when you open a hot water valve and turns off automatically once the tap is closed.

    Electronically controlled

    The intuitive user interface enables your to easily monitor and adjust your hot water system. You can check the set temperature and current energy consumption using the backlit display and adjust the settings using the rotary selector.

    Three-fold intelligence technology

    This electric hot water system features three-fold intelligence technology which uses temperature sensors at the inlet and outlet and also uses a flow sensor. This maintains a consistent water temperature for your comfort and convenience.

    Compact design

    Thanks to the continuous flow system, you don’t need a big storage cylinder to keep hot water. This makes this system a compact solution for your hot water needs, making it easy to find a place to install the unit.

    Questions & answers

    Are there any specific electrical requirements for installation of the Del18 Plus hot water systems ie three phase power? We are located in an apartment building, would current provision of power via s/board be a issue? David21 · 2020-06-26
