All about GROHE CO₂ bottles

FAQ

How much sparkling water can I get from a CO2 bottle?

The 425 g CO₂ bottle provides up to 60 litres of sparkling water. A 2kg CO₂ bottles provides up to 350 litres of sparkling water. The actual amount of litres can vary as binding of carbon dioxide in water is affected by various factors, e.g. if you draw sparkling or medium sparkling water, or on the temperature and water hardness of the water.

How do I know that the CO2 bottle needs to be replaced?

The remaining capacity of the CO₂ bottles is shown on the cooler LED display while you are tapping carbonated water. You will also see the remaining value on the GROHE Watersystem app. Depending on your settings, you will receive a push notification from the app as soon as the CO₂ level has fallen below a certain threshold. The LED on the left handle of the tap flashes white 5 times if the capacities has fallen below 10%.

When the CO₂ bottle is completely empty (the water is only a trickle and does not sparkle anymore), the display of the Blue Home cooler shows EC. Then please replace the CO₂ bottle and reset the CO₂ settings.

How do I exchange the empty bottle on my GROHE Blue Home system?

The CO₂ bottles is exchanged within seconds only: open the cover of the Blue Home cooler, unscrew the used bottle and screw in the new one. Finally, reset the CO₂ settings on the cooler or on the app (see also next question). Here you can read more about the CO2 bottle exchange.

How do I reset the CO2 system settings after replacement?

Following the exchange of a CO₂ bottle, the system settings must be reset. Please press down the right button of the Blue Home cooler until the display starts flashing. The message “ro” appears in the display. Then press the right button until the display stops flashing.
If you draw water containing carbon dioxide, you will now be shown the remaining capacity of the CO₂ bottle.
If you use the GROHE Watersystem app, you can easily reset the system settings on the app after each exchange of the CO₂ bottle or the filter.

I inserted a new CO2 bottle. The LCD display of the Blue Home cooler still does not show full capacity.

The standard view on the LCD display shows the capacity of the filter, not the capacity of the CO₂ bottle. When you draw water containing carbon dioxide, the cooler will show the remaining capacity of the CO₂ bottle. Tipp: Download the GROHE Watersystems app to see the capacity of the CO₂ bottle and filter anytime on your mobile device.

Can I also install the CO2 bottle horizontally?

No, the CO₂ bottle must not be installed horizontally. Due to safety measures, please also store them in vertical position.

How many bottles do I need?

Each GROHE Blue Home starter kit set contains one 425 gr CO₂ bottle. During your first order in our web shop, you order the CO₂ starter kit (item no. 40422000), which comes with four bottles. In total you will have five CO₂ bottles at home, so that you can easily return four bottles every time when they are empty in exchange to new ones (item no. 1038619990).

If you use a GROHE Blue Professional system, we recommend ordering two 2 kg starter bottles (item no. 40423000), so that you can easily return one empty bottle in exchange to a new one (item no. 40424000) while keeping the other bottle connected to your system.

How can I adjust the level of carbonization?

The GROHE Blue faucet provides filtered still water (top button on the left handle) or filtered sparkling water (lower button on the left handle). If you press both buttons in sequence, the faucet provides medium sparkling water.

However, carbon dioxide binding in water is affected by various factors. For example, the colder the water from the cooler, the more carbon dioxide can be bound in the water.
