Increasing Water Temperature on Junkers ED18-2S and Siemens DH18200 Water Heaters

Hello good Morning. I have a Junkers ED18-2S water heater model very similar to the Siemens DH18200 water heater. Could someone please tell me what I need to do to increase the water temperature? Thank you very much in advance.

Hello! To increase the water temperature on your Junkers ED18-2S water heater, you can follow these general steps:


Locate the temperature adjustment dial on the water heater. It is usually found on the front panel or near the control unit.

Turn off the power to the water heater before making any adjustments. This is important for safety reasons.

Use a screwdriver or a similar tool to adjust the temperature setting on the dial. Turn it clockwise to increase the temperature.

Wait for the water heater to reach the new temperature setting before testing the water temperature at the tap.

Monitor the water temperature and adjust the setting as needed to achieve your desired hot water temperature.


Please note that specific instructions may vary depending on the exact model of your water heater, so it's always a good idea to consult the user manual or contact the manufacturer for detailed guidance.

Hello. The heater is very simple in design. The lower the flow in the tap, the warmer the water (this is how we regulate the temperature; if the flow is too low, the heater will turn off). These heaters are suitable for washing your hands in the sink when there is barely any water, but I wouldn`t count on a comfortable shower in this case.
Regards.

It has 18kW, you can easily take a shower in Spain.
If it`s too cold, it`s possible that one/two heaters are damaged or not getting power.
