Frequently Asked Questions

Can I use this with other brewing systems?

Yes — it works with any all-grain brewing system that uses sparging. Set your desired water temperature and use the tap to dispense.

Will it maintain temperature if I step away?

Yes — once the set temperature is reached, the element cycles on and off to hold it steady until turned off.

Does it have boil protection or auto shut-off?

No — it’s designed as a water heater, not a kettle. Always monitor it and don’t let it run dry.
