FAQs
Stiebel Eltron DHE 27 3-Phase Electric Instant System — Frequently Asked Questions
What is the Stiebel Eltron DHE 27 AU?
The DHE 27 AU is a German-made 3-phase electric instantaneous (instant) water heater with a 28kW output. It heats water on demand — no storage tank — and uses 4i Technology to deliver precise hot water anywhere from 20°C to 60°C.
What is 4i Technology?
4i Technology is Stiebel Eltron's intelligent, fully-electronic control. Its sensors continuously compensate for changes in water pressure and flow, so the temperature you set is the temperature you get — accurate to the degree.
What's the difference between the DHE and the DEL Plus?
Both are German-made 3-phase electric instant heaters. The DEL Plus delivers up to 50°C (no tempering valve needed) with 3i control, while the DHE AU delivers precise temperatures up to 60°C with advanced 4i technology and a consumption display. We'll recommend the right one for your home.
Is the DHE 27 AU suitable for apartments?
Yes — the DHE range is extremely common in modern high-rise apartments and is ideal for larger units and homes on 3-phase power. If you need a new unit or a repair in an apartment, there's a strong chance it's a Stiebel Eltron DHE or DEL.
