On a side-by-side tea maker, preparing water and keeping the teapot warm are different jobs. The kettle prepares the water, tea brews in the teapot and filter, and the teapot warmer helps maintain the vessel’s heat at the appropriate stage. Separating those tasks makes base-function selection clearer and gives you a more useful way to understand changes in the tea.
What do the kettle and teapot do on the STM-1822S?
The STM-1822S side-by-side tea maker is listed with a kettle, a glass teapot, touch controls, a digital base, a steel filter and a teapot warmer. Its side-by-side arrangement provides access to both vessels as one set and lets you organise the routine around the distinct purpose of each.
Do not add the two nominal capacities together and treat the result as the amount of tea to brew at once. Kettle water volume, tea in the pot and the permitted filling level of each vessel are separate considerations. Choose the amount needed, then follow the markings and appliance instructions. Filling further is not a substitute for planning the quantity of tea.

Prepare the work area before switching on
Place the base on a stable, suitable surface with enough room to lift the kettle, open the lid and take hold of the teapot handle. Keep the cord route away from the path of a hot vessel. Check that connection surfaces are dry, vessels are seated properly and the filter is ready. Knowing the working layout prevents rushed adjustments halfway through brewing.
Read the base-function names or symbols in the instructions for this exact model. Before selecting a function, identify whether the present task is preparing water or keeping the teapot warm. A digital panel does not imply the same setting sequence on every appliance. Choosing the function deliberately makes the STM-1822S controls more useful in an everyday routine.
Keep water preparation, brewing and serving as separate stages
First prepare an allowed quantity of water in the kettle. Then use tea and water in the teapot and filter according to the tea type and the appliance method. Track brewing time from that stage: water-heating time and the time tea remains in contact with water are not one interval. When moving the kettle, allow for the handle position and the steam path.
Once the tea reaches the result you prefer, manage continuing leaf contact according to the permitted method. If the teapot is placed on the warmer for holding, select the relevant function as described in the instructions. Hot tea does not by itself mean brewing should continue. Matching the routine to the tea and the amount to be served gives you clearer control of the result.
A task table for the tea-making routine
Stage | Main part | What to follow |
|---|---|---|
Prepare water | Kettle | Permitted fill level and appropriate function |
Prepare the tea | Teapot and filter | Tea quantity, water volume and correct placement |
Brew | Tea in contact with water | Time and preferred result for that tea |
Keep warm | Teapot and its warmer | Permitted holding function and vessel condition |
Pour and serve | Each vessel’s handle and spout | Secure handling and a clear movement path |
Finish | Vessels and base | Switch-off and cleaning according to instructions |
If the tea becomes strong quickly, change one factor at a time
For the next batch, note tea quantity, water volume and contact time. If the result is stronger than you prefer, review those three factors first and change only one on the next attempt. Changing quantities, water and controls together makes the reason for a different result harder to identify. Using a similar cup for tasting also helps keep the comparison consistent.
A single numerical temperature is not a universal recipe for all tea. Read the tea instructions together with the permitted setting range and method for the STM-1822S. Interpret the display using its own guide rather than assuming the indicator gives the exact temperature everywhere in the teapot. This makes informed use of the digital base a practical part of the routine.
After serving, prepare the set for its next use
Finish by switching off as instructed, then disconnect power and allow the required cooling before cleaning. Clean the filter and teapot using permitted methods and materials, and do not immerse the electrical base. Avoid improvising abrupt temperature changes for the glass pot or a descaling process; the product instructions are the reference for the precise care method.
If you are still deciding on the layout, see the stacked versus side-by-side tea maker guide. To review models, visit the Swiss Plus tea maker category. The aim of this routine is clear use of kettle, teapot and warmer so preparation and serving fit your daily habits.
