Instantaneous water heaters can deliver higher outputs
Stiebel Eltron’s DHE range of 3-phase electric instantaneous water heaters is available in ratings of 18, 21, 24 and 27 kW. Once the water temperature has been set, it will be maintained under all circumstances. These water heaters are said to be ideal for the leisure, hospitality and health-care sectors, where a duty of care relating to hot water exists. All L8 requirements for health and safety are met.
These water heaters are intended to be installed close to the point of use and have release springs to close the valve if unattended. A safe tray or drain is not required, and temperature control is reliable to within ±0.5 K.
