DHC tankless water heaters are ideal for residential and commercial point-of-use sink applications including: bathrooms, cabins and cottages, office buildings, stores, malls, warehouses, restaurants, and gas stations. They heat water instantaneously and endlessly at 99% efficiency as it flows through the unit. Because they do not store hot water like tank water heaters, they have no stand-by energy losses. Venting is not necessary and the compact European design can be installed with the unit visible. The hot water temperature delivered by a DHC depends on the incoming cold water temperature, the flow rate through the unit, and the size of the DHC model. They excel at supplying water at a constant temperature but the model must be carefully matched to the flow rate of the sink to operate properly. Refer to the DHC Sizing Guide to determine which model you need. Call Stiebel Eltron at 800.582.8423 with any questions. Stiebel Eltron invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader today, with an engineering and manufacturing tradition of excellence.
