Stiebel Eltron DHC Classic Series
Point-of-Use Tankless Water Heater

The Stiebel Eltron DHC series tankless water heaters are economical, ultra-compact, attractive, and well built point-of-use tankless water heaters designed for basic point of use applications such as bathroom sinks, kitchens, commercial washrooms, emergency eyewash stations, etc. The DHC series is best suited to applications with a relatively constant flow rate. If the flow rate is likely to fluctuate in your application due to varying water demands or changes in well pump pressures, etc., we recommend that you consider a DHC-E Series tankless water heater with thermostatic control and flow-based power modulation technology.

Due to their small size, Stiebel Eltron DHC Classic Series water heaters conveniently fit directly under the sink or adjacent cupboard or closet, so they deliver hot water to the sink almost instantly. By locating the heater right near the point-of-use, you can also eliminate thermal heat loss commonly associated with long pipe runs. In new construction applications, you also eliminate the need to run a hot water line all the way from the main central water heater which can save you significant money in plumbing and material cost.

By producing hot water on demand only as it is being used, DHC Classic Series tankless water heaters are extremely energy efficient. A sophisticated water flow sensor recognizes when hot water is being used and when it has been turned off, so the unit will activate and deactivate automatically so it only runs when you are actually using water. This eliminates standby thermal heat losses associated with traditional tank type water heaters. Accordingly, you can expect to see a significant cost reduction over the operating cost of a conventional water heater.

An exclusive scald-guard thermostat keeps the water temperature within safe limits at all times. Additionally, the DHC water heaters are equipped with a safety high-limit with manual reset. The rugged all copper design ensures many years of reliable service.
