No cool-down wait to add water
Use the pump to transfer water from the separate tank into the boiler while the system remains under pressure.
Battistella Barbara 31 Semi-Automatica | Pump + tank + EOS iron
Refill the boiler without stopping to cool down
The Barbara 31 Semi-Automatica adds a 48W pump and separate 10L water tank to the proven 4.5L stainless boiler and weighted EOS iron. Pump-assisted refilling lets you add water while the boiler remains pressurised, supporting a smoother, continuous pressing workflow.
- 10L external water tank and 48W pump reduce interruptions for cooling and manual refilling.
- Refill while the boiler remains pressurised using the operator-controlled pump system.
- 3.4L usable stainless boiler capacity maintains a substantial working steam reserve.
- 2.8-bar working steam pressure delivers controlled steam through the EOS iron.
- Wheeled floor-standing format keeps the complete system organised beside the workstation.

A more continuous workflow, with water level under your control
Operator-controlled filling
Switch the pump on when water is needed, watch the boiler level, then switch it off at the desired level.
10L supply close at hand
The external tank provides a much larger water reserve than a manually filled Barbara alone.
Built for a productive pressing rhythm
Keep working instead of waiting for a hot boiler to cool
The semi-automatic system avoids opening the safety cap for routine refilling. Add distilled water to the separate tank, use the pump switch to bring the boiler back to the desired level, and continue once the steam system is ready. The full station measures approximately 25 × 47 × 89cm and rolls into position beside the ironing table.

Stop at level
Switch the pump off once the desired level is reached; never exceed the MAX mark.
Heat
Switch on the boiler and iron and wait for the gauge to reach approximately 2.8 bar.

Use distilled water and flush the boiler weekly
Protect the boiler and pump
Distilled water helps minimise scale and residue from minerals and treatment chemicals found in tap water.
- Use distilled water in the external supply tank.
- Keep enough water in the tank whenever the pump is used; never run the pump dry.
- Drain and flush the boiler once a week.
- Drain only when the system is cold, unplugged and the gauge reads 0 bar.
- Wait at least one hour after switch-off before draining.
- Never add fragrance, starch, special ironing water or chemical treatments.
Safe everyday operation
Connect the Barbara Semi-Automatica directly to a correctly earthed 230V outlet suitable for its 2298W load.
- Avoid multi-boxes and unsuitable extension leads.
- Monitor the boiler-level window whenever the pump is running.
- Switch the pump off once the desired boiler level is reached.
- Never move the system while it is hot, operating or pressurised.
- Never open the safety cap while the generator is operating or pressurised.
- Always return the hot iron to its supplied rubber rest.

What does “semi-automatic” mean?
The boiler can be refilled from the separate 10L tank using an electric pump. You control the process with the pump switch: turn it on to add water, watch the boiler-level window, then switch it off at the desired level.
Can the boiler be refilled while it is hot?
Yes—use the external tank and pump system. The manufacturer states that this method can add water while the machine remains pressurised, avoiding the usual cool-down wait. Never open the safety cap while the boiler is hot or pressurised.
Does the pump stop automatically?
No. This is why the model is described as semi-automatic. The operator monitors the level and switches the pump off once the desired boiler level is reached.
Is the total water capacity 13.4L?
No. The pressurised boiler has a 4.5L vessel and 3.4L useful capacity. The separate 10L tank supplies water to that boiler through the pump; it does not increase the boiler vessel itself to 13.4L.
How long can it provide steam?
The pump-assisted system is designed for a continuous pressing workflow rather than one fixed runtime. Keep distilled water available in the 10L tank and refill the boiler as needed using the pump and level window.
Why must the supply tank contain water?
The pump relies on water from the external tank. Running it dry can damage the pump, so check the tank level before activating the refill switch.
Why is distilled water important?
Distilled water reduces the minerals and treatment chemicals entering the boiler and pump, helping limit scale and residue. Do not add perfume, starch, special ironing water or chemical treatments.
How often should I drain the boiler?
Drain and flush it once a week. The machine must be cold and unplugged, the pressure gauge must read 0 bar, and at least one hour should have passed since switch-off.
What electrical connection does it need?
The Barbara 31 Semi-Automatica is rated at 230V / 50Hz and 2298W. Connect it directly to a suitable, correctly earthed outlet and avoid multi-boxes and unsuitable extension leads.
