It heats water in a consistent manner and since it is very sleek and compact, therefore, you can install it anywhere like above the sink. It is equipped with the best and top-quality components; the copper heating coil not only heats water quickly but also ensures long lasting performance and trouble-free maintenance. The unit’s flow switch controls the heating element and the manufacturer has provided another switch for resetting the heater. It has a Scaldguard thermostat that lets the device maintain safe water temperatures.

  • It heats water when you demand it and doesn’t store water
  • It utilizes approximately half the amount of energy that a conventional tanked heater would use because it doesn’t involve constant supply of gas or electricity for maintaining its water reserve temperature
  • It is much more safe and reliable option than tanked heaters because it is equipped with a built-in thermostat that can detect overheating incidence and will stop operating immediately


  • It cannot maintain high water temperature and this becomes very irritating when you need very hot water
  • The efficiency of this unit can be affected substantially if more than one water outlets are in use because the unit only offers limited amount of hot water

Installation and Specifications

Common Problems

The most commonly faced problem with this model is if insufficient supply of hot water. The heater does not heat water according to the required temperature and water may remain lukewarm in cold weather. However, in warmer areas the product works fine. This means this heater is perfect for being used at southern regions. Moreover, for a small flat and a family of 2 to 3 people this unit is ideal but for medium to large families, this is not a feasible choice of heater.


Overall, the Stiebel Eltron DHC 6-2 is an excellent water heater, one without many flaws, and the great features it does possess outweigh the minor flaws in its operation.
