Tankless Water Heaters

Arc Solar carries a variety of electric and gas tankless water heaters. These range in output from 3Kw to 30Kw, and are used in residential and commercial applications.

Tankless water heaters are used in thermal solar systems to maintain water temperatures during periods of low solar radiation. This is done in an 'on-demand' basis. Tankless water heaters save energy, as they come on only when needed. Tankless water heaters typically save the customer 30% over conventional water heating methods. Arc Solar carries quality brands such as Bosch, Stiebel Eltron, and Viessmann.

Stiebel Eltron

As an international leader in tankless water heating, Stiebel Eltron has pioneered this technology. The company's German engineering and manufacturing tradition of excellence means that you can depend on it's performance for many years to come. The DHC-E has several temperature and flow sensors, which feed their readings into the unit's microprocessor control. Heating elements are engaged in stages, achieving the temperature you desire. The DHC-E continually monitors the water temperature it produces.
