JUMAG electric steam boiler EDI

The EDI series steam boilers are electrically operated. They provide steam outputs from 20 kW to 360 kW. This capacity can be multiplied with multiple units – incidentally also in hybrid operation with oil- and gas-fired steam boilers.  

JUMAG electric steam boiler EDI Fail-safe and sustainable - up to 480 kg steam/h

JUMAG oil- or gas-fired steam boilers in detail

How it works

Why do JUMAG steam boilers require minimal maintenance and boast maximum energy efficiency? This is due to the fact that they work differently from the classic electric steam boilers.

Depending on the water level in the pressure vessel, the feed water is refilled into the pressure vessel through the integrated boiler pump.

Low surface load on the heating rods due to larger diameter and longer heating rods. Approx. 10 W/cm² compared with up to 26 W/cm² for competitors

Wear-free control of the heating rods: Thyristors switch during phase change without voltage, unlike contactors, which switch and wear out with voltage. Thanks to the thyristors, the power grid is protected because current peaks are avoided during switching

All materials are made from high-quality stainless steels. Optionally completely made of V4A (all components without exception!)
