Table of contents FAQ

Power consumption

How much power does ELIAH need?

This is very much dependent on the usage time of ELIAH. At most, ELIAH consumes 2 kWh per hour. In the typical applications, we were able to determine these daily consumptions:
  • Bath: 0.4-0.6 kWh / day
  • Home office: 3-4 kWh / day

What are the costs of electricity consumption?

Assuming an electricity price of 33 cents/kWh, ELIAH costs a maximum of 11 cents in 10 minutes. By comparison, hot water for 10 minutes of showering in Germany costs at least 78 cents (5.20 € / 1000 L). ELIAH saves energy costs by heating only when needed and lowering the room temperature when the room is not in use.


How heavy is ELIAH?

ELIAH weighs 4 kg.

How is ELIAH mounted?

First, the ELIAH mounting tray is mounted to the ceiling with 4 screws. Then the device is hung in order to connect the electrical installation and to attach the fall protection. Then the device is magnetically snapped into the mounting tray.

ELIAH does not snap correctly into the mounting tray

Please check the following points:

  • The electrical installation is correctly stowed and cannot be trapped. In case of very long installation cables may have to be shortened. Please note that shortening the cables at ELIAH should only take place when you no longer wish to make use of a "money back guarantee". Please also note point 4.3 in the operating instructions and especially Figure 3.
  • The mounting tray may be strained. This is possible due to an uneven ceiling, imprecise drill holes, or overtightening of the installation screws. You can loosen the screws to the ceiling until the corners of the mounting tray just touch the ceiling.
  • If the drill holes are not precise and you no longer want to claim a "money back guarantee", the mounting shell can also be adapted to the drill hole. To do this, you can take a 5 mm metal drill bit to widen the existing mounting hole accordingly, or even to set completely new mounting holes. For this, we recommend a position as close as possible to the original mounting hole, but also positioned so that the screw is not visible from the outside later.
  • The mounting ropes may be in the way. As soon as the electrical installation is connected and the guardrail has been mounted, you can also unhook the mounting ropes again and stow them separately in the corners in advance. Just make sure that the mounting ropes do not cover the magnet supports.

Can I also mount ELIAH vertically?

No, unfortunately this is not possible. ELIAH must be installed horizontally.

To which circuits does ELIAH fit?

To circuits with 4 amp, 6 amp or more than 10 amp fuse protection. The unit can be configured for a lower maximum heat output of 800 watts or 1200 watts. This corresponds to circuits with 4 ampere or 6 ampere fuse protection.

For maximum heating power and use as a rapid heater, the circuit should be rated for at least 10 amps. However, lower heating capacities are still suitable for small WCs or bathrooms. The ideal design includes: 

Circuit breaker (>= 10 amps), wires (usually >= 1.5 mm^2) and light switch (>= 10 amps).

How is ELIAH connected electrically?

As a "protection class 1" device, ELIAH requires a single-phase connection. Must be connected:

  • Protective earth (PE = green/yellow)
  • Neutral (N = blue)
  • Ladder (L = brown)

The existing terminals or other gas-tight terminals must be used for connection! 

Do I need a special light switch?

For use as a rapid heater, existing light switches are usually sufficient. The light switch must be rated for 10 amps or more.

To use the timer functions, it is necessary to use a pushbutton (changeover switch, installation as normally closed). Here, too, the switch must be designed according to the current intensity.

Configuration on the device

How is ELIAH programmed?

ELIAH is configured via the three buttons next to the display. All settings can be taken from the enclosed operating instructions.

Can I reset ELIAH to factory settings?

Yes, to do this, press the "up" and "down" arrow keys until the device displays "fACt".

ELIAH does not heat during programming, is this normal?

ELIAH switches off the heating for various reasons as long as you are configuring the device. If you are in a program with heating function, the heating will start 10 seconds after you exit the menu.

The menu for timer settings cannot be selected

The menu for timer settings is activated if you have connected the device via a changeover switch (normally closed); or have also configured this in the global settings. Since the timer functions do not work without a permanent power supply to the device, the menu otherwise remains hidden.

Operation at the light switch

How does the operation on the light switch work?

ELIAH has up to 8 freely configurable programs, which can be called up via normal light switches.
If the light is switched on normally, program 1 starts.
If the light is switched off and switched on again within 5 seconds, program 2 starts.
For each repetition, the program number increases until the maximum number of desired programs is reached. If this is the case, program 1 starts again.
If the light is off for more than 5 seconds, the unit restarts with program 1.
The number of programs and their function is set on the device itself.

How does the operation on the light switch work if this is a changeover switch?

ELIAH is woken up from standby mode by pressing the button. If the button is pressed again within 5 seconds after the wake-up, the device switches to the next program. If the button is pressed again only after 5 seconds, ELIAH switches to the Standby mode.

Can ELIAH always start with the last selected program?

Yes, this is possible. Both for operation with the light switch and with a changeover switch (normally closed). Please refer to the "Global settings" item and the "Start selection" menu item in the operating instructions.

Technical equipment

Why does ELIAH not have a remote control?

We have tested a remote control for ELIAH but decided against it for the time being. After a short period of familiarization, the operation on the existing light switch is, in our opinion, the best possible variant.

Why does ELIAH not have a ceramic heating element?

Ceramic heating elements have a limited a limited surface temperature without an active air supply. This means that even no dust is burned during start-up and the formation of odors is minimized. This is particularly necessary with inexpensive fan heaters, since these are often operated with simple motors, which are switched on at the same time as the heating element. are switched. This means that the heater is already heating, even if there is still no and without a ceramic heating element, high temperatures of the heating element can occur here, which favors the burning of dust of dust with the development of odors. Also, the air flow rate of a canned motor can be motor may be reduced over its service life, causing the heating element to develop higher operating temperatures and thus possibly burns dust. Ceramic heating elements are therefore particularly useful in conjunction with low-cost motors without speed ceramic heating elements therefore make sense.

The heating element of ELIAH is made of corrosion-resistant constantan wire. Due to the fact that we turn on the heater only when the air flow of the blower is we have ideal heat dissipation from the first moment and the risk of burning dust is minimized. of burning dust is minimized. In addition, we monitor the speed of the of the blower and the heating is switched off if the required speed is no longer present. is no longer present. Other advantages of the heating element made of constantan wire heating element are its low heat capacity and small volume, which has enabled us to achieve a compact design in ELIAH we were able to achieve a compact design.
