The warm water comes from an electric boiler in the winter and from the solar heater during the rest of the year. Here’s how to switch between winter and summer mode and back.

The electric boiler and taps:

The taps:

Same photo as above, but with the taps marked:

Summer mode:

• The yellow tap must be turned clockwise all the way to the right
• The red tap must be in a horizontal position pointing toward you
• Remove the electric plug from the wall socket

Winter mode:

• The yellow tap must be turned anti-clockwise all the way to the left
• The red tap must be turned upwards in a  vertical position
• Plug the electric plug into the wall socket

That’s all there is to it!
