FAQ
Contact your local energy provider and inform them of your address. They will be able to let you know if you have three-phase power available at your address.
You will need to check with your electrician to find out how much 3 phase power is available in "Amps per phase". The DHB-E 18 LCD water heater requires 27 Amps per phase, whereas the DHB-E 27 LCD requires 40 Amps per phase.
You will need to confirm the amperage supply to the hot water unit from the circuit breaker in the switchboard. Please contact us to confirm the appropriate instantaneous electric hot water system.
As a general rule, the instant hot water system required will be based on the number of hot water outlets the hot water system needs to service, along with the incoming cold water temperature. As a general guide in an apartment/house with 1 bathroom, a 19.4kW three-phase electric instantaneous water heater (e.g. DHE 18 LCD, DEL 18 AU or DHB-E 18 LCD) is suitable. In a house with 2 bathrooms, a 28-29.1kW three-phase electric instantaneous water heater (e.g. DHE 27 AU, DEL 27 Plus or DHB-E 27 LCD) should be selected.
Underneath the dial that adjusts the temperature there is a flap that pulls forward and then drops down. A rating label is located up under the flap showing the model and size - DHB-E 13 LCD, DHB-E 18 LCD or DHB-E 27 LCD. Within the downloads section of the DHB-E you can download a pdf showing you exactly where and how to locate this sticker.
The DHB-E LCD range can deliver hot water at 60 degrees Celsius. If supplying hot water for a domestic bathroom, the plumbing regulations require the installation of a temperature control device to supply water not exceeding 50°C. Alternatively, the STIEBEL ELTRON DEL Plus instantaneous electric water heater may be a suitable choice which delivers hot water not exceeding 50 degree Celsius in accordance with AS3498. Click on the DEL Plus product to find out more.
The water heater can be installed almost anywhere due to its compact size. The water heater does not require ventilation, relief drain or safe trays so it can be installed in a cupboard, in the roof space, below the sink, in a service cavity, in a Euro laundry just to name a few options. If installing outdoors the hot water system must be protected from the elements by a protective covering such as a meter box.
The DHB-E LCD water heaters are designed to be installed as close as practical to the most used hot water outlet. Installing closer to the point of use can help to save water and energy by delivering hot water quickly to the outlet. The STIEBEL ELTRON three-phase electric instantaneous water heaters are designed to service multiple outlets located several metres away from the system.
Compared to a storage hot water unit an electric instantaneous water heater can be up to 30% more efficient. This is due to the water heater not storing any hot water and having heat losses from storing a body of hot water.
