The next generation DEL

DEL Plus – the instantaneous water heater for the housing sector

With the DEL Plus, world market leader Stiebel Eltron is presenting a further upgrade of the DEL SL instantaneous water heater, which is particularly popular in the housing sector.

In the “Plus” mid-size product category it is the ideal device for decentralised water heating. Featuring a new design and a modernised multifunctional display, operation of the DEL is now even more convenient. The new version is also ideal as an under sink unit: the device’s screw cap ensures easy operation in every installation situation. As well as comfort and convenience, energy efficiency has also been improved: the three-stage ECO mode offers maximum energy efficiency. Switching to the new generation of devices is child’s play thanks to PROFI-RAPID. Existing drill holes and connections for a previous Stiebel Eltron instantaneous water heater can be used. The selectable rated power (18, 21 or 24 kW) is conveniently set by jumper in the device during installation. The temperature of the new DEL can also be set precisely and stored on two memory keys. Scalding is prevented by activating the integrated temperature limiter.

The DEL Plus is equipped with 3i technology which makes it “intelligent”. This permanently monitors the relevant parameters to ensure a constant and precise outlet temperature right up to the maximum output. The outlet temperature remains constant, even with pressure fluctuations in the pipe network.
