DEL Instantaneous 3 Phase Water Heater
Overview
Stiebel Eltron’s new DEL family of three-phase 415V electric mains pressure instantaneous water heaters provide unprecedented choice for users and developers. The three phase water heaters utilise sophisticated electronic technology to maintain water delivery temperature at 50 degrees - overcoming the need for a separate tempering valve, and making them ideal for bathroom applications.
The DEL three phase instantaneous water heaters are 20 to 30% more energy efficient than conventional storage electric hot water systems. The instantaneous water heating technology saves you money and helps to conserve our natural resources.
The DEL unit's small size and electrical operation allow installation directly at point of use while both simplifying and reducing the cost of installation. The DEL water heaters are suitable for use in apartments and homes, office fitouts, schools and gyms.
The DEL units are 3 phase water heaters with 415V electric mains pressure instantaneous technology, featuring an LED display for water temperature. The DEL 3 phase water heaters are available in two sizes, the DEL -18 A to suit an apartment with one bathroom and the DEL 27 A to suit an apartment with two bathrooms.
