The Stiebel Eltron Mini Series tankless water heaters are economical, ultra-compact, attractive point-of-use tankless water heaters designed for basic low-flow point of use applications. The Mini 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 8 tankless water heater with thermostatic control and flow-based power modulation technology.
Due to its small size, the Stiebel Eltron Mini 4-2 conveniently fits directly under the sink or adjacent cupboard or closet, so it delivers 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. If the Mini 4-2 can supply all of the hot water needs for the room, 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, the Mini 4-2 is 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.
