Stiebel Eltron Hot Water Systems

2 Phase electric instantaneous hot water heater

One of Stiebel Eltron’s most popular hot water systems on the Australian market is the 2 phase electric instantaneous hot water heater. One of the major drawcards of this style of system is the precise temperature control that it allows. Instantaneous hot water units are also growing in popularity. This is due to growing concerns about the amount of energy that can be wasted by preheating water in storage tanks.

3 phrase instantaneous water hot heater

A Stiebel Eltron 3 phase instantaneous water heater ensures that heat loss due to storage is eliminated. It also facilitates conservation of space, making these systems ideal for smaller homes or units were area for hot water systems are scarce. The 3 phase instantaneous hot water heater is so compact and space-efficient that they do not require a safe tray, flue or ventilation. As such, the areas in which this system can be installed are far more flexible than a storage style system.

Single phase electric instantaneous hot water system

Stiebel Eltron single phase electric instantaneous hot water systems are best suited to situations in which the hot water demand is low. Such as in basins or sinks. This is due to the fact that these units have a correspondingly lower flow rate of around 1.5 litres per minute. Similar to the Stiebel Eltron 3 heaters, the single phase units are extremely energy efficient and deliver hot water on demand. One major advantage to the single phase units is that the small size of these systems mean the units can be installed in areas where conventional storage units would not fit.

Open vented compact storage water heater model

Another option to provide water to your sink or basin is the open vented compact storage water heater model. These units are manufactured with the goal of providing immediate point of use hot water. This is particularly good for situations where the sink or basin is situated a significant distance from the home’s primary hot water unit. Furthermore, by locating one of these small units at your sink or basin there is the added benefit of energy conservation. This is because heat loss during long stretches of pipe from a centralised system is eliminated.

Mains pressure compact storage water heater

Similar to the Stiebel Eltron open vented compact storage water heater, the mains pressure compact storage water heater is designed for situations where hot water is needed without delay. This is good for sinks and basins. The major difference between the two styles of systems is that the mains pressure compact storage water heater is designed to service multiple points. It also has a correspondingly higher capacity of up to 15 litres. The one necessity for these systems is the availability of a power point, as the Stiebel Eltron operates on 6.5Amp 230V and must plug into a power point.

Heat pump hot water system

This passes on significant financial savings to the customer as well producing less greenhouse gas emissions. Much like a solar hot water system, heat pumps harvest environmental energy to heat your water, however the major difference is that whilst solar hot water systems capture the sun’s energy using solar panels installed on the roof, heat pumps utilise heat that is contained within air. This is advantageous as the system can operate when sunlight is scarce, as well as at night. What’s more, as no solar panels are required, you do not have to worry about damage to the panels due to extreme weather conditions.
