Of all Stiebel’s systems, the one most commonly installed in the NSW market is the “DHF”. Having been specifically produced for NSW’s 3-phase instantaneous replacement market, this water heater is an ideal replacement for any such system (i.e. Wilson, Hocking, Dux, Simplex and Langco).
The most commonly installed of these Stiebel Eltron water heaters is the DHF 13 (due to it using only 19.7 amps per phase to fit onto existing electric wiring and therefore using the least amount of electricity — in comparison to the DHF 15 which uses 22 5 Amps).
This DHF 13 is able to supply the following standard flow rate output of hot water :
These flow rates (coming from this particular water heater) provide constant flow of hot water at a temperature of at least 40 degrees — ample for most households and usages.
One note of caution is that these DHF units are not able to be used with water-saving shower heads or tapware (as the reduced flow rate is not compatible with these water heaters).
Its dimensions are 370mm x 220mm x 130mm, and it weighs in at a very light 4kg. Encased in a pressure resistant copper tank, this water heater, with its tubular heating system, has a nominal capacity of 0.6 litres.
This Stiebel Eltron water heater has a unique 2 dot switch display, indicating a half power option for summer and a full power option for winter (which will assist with saving energy). Additionally, this hot water system has Australian Standards WaterMark approval.
Another distinguishing factor is that it does not require ventilation (i.e. it is an open vented water heater and thus doesn’t require a relief line). That is, whereas the competitors’ units all require a relief valve and relief line, the Stiebel Eltron water heater does not.
Finally, the DHF can be counted upon to provide you the hot water you need all year round, whether you be in an apartment, home or office, whilst saving you power with its three phase technology.
|Flow Rate (L/min)
|8.2 (at showering temp 40°C)
|5.9 (at kitchen sink temp 50°C)
|9 (at showering temp 40°C)
|6.5 (at kitchen sink temp 50°C)
Another range of 3-Phase electric hot water systems is the ‘Stiebel Eltron DEL Instantaneous”.
This range comes in 2 models, both having a 2.5 litre/min capacity.
The Stiebel Eltron DEL Instantaneous’s modern compact design gives you the flexibility in installation options as well as reducing installation costs.

Stiebel’s “DHB-E & DHB-E 13A Instantaneous” range is the next step up. The DHB-E modern electronics enables up to 20% less energy and water than hydraulically controlled units. On the other hand, the DHB-E 13A is electronically controlled to maintain water delivery temperature not exceeding 50°C.
Stiebel Eltron has almost 40 years experience in developing heat pump technology and the company introduced its latest model, the WWK 300A, to the Australian market in 2006. The WWK 300A Heat Pump is an energy efficient water heating solution for your home, backed by German engineering and manufacturing, and designed specifically for Australia’s conditions.
This system has the advantage of being both a single unit (easy installation) and one that can be installed either indoors or outdoors (flexibility). Such flexibility with its installation gives it an advantage over the other heat pumps in the market, where outdoor installation is the only option.
With regards to an outdoor installation, it comes with an active defrost function allowing it to operate in colder climates. Additionally, the cylinder capacity is a generous 300 Litres, meaning it has one of the highest deliveries of hot water for a heat pump, again in comparison to many of its competitors whom offer a standard 250 litre capacity. When installed indoors, it needs to be in a room with a minimum of 13 cubic metres of space. With this in mind, it is often installed in a garage or large room.
The air solar system of the Heat Pump utilises energy from the environment, and whether indoors or outdoors, it is able to draw the ambient air into the system to begin its heating process. In this way the WWK 300A doesn’t rely on the sun to create energy (as a solar system does), but rather the air surrounding it. A further distinguishing factor is that it can be installed and operated on either ‘Off-Peak’ heating or on ‘Continuous’. This is an advantage because some other competing heat pumps can only be operated one way (i.e. not allowing any flexibility). Additionally it can be operated on a timer (if available) or even on extended ‘Off Peak” times. When in operation, it uses the least amount of power (i.e. only 2.3 amps) of all competitors, making it therefore more energy efficient. Regarding the installation, further flexibility is offered in that a 1.5 metre long power lead is connected to it.
