    > you bring the hot water

What type of hot water supply is needed?

E.g.

- Hot water poured in from a kettle?

- Hot water plumbed in from a domestic hot-water supply?

- Hot water plumbed in from a boiling water tap (such as Quooker?)

Reading the manual, it seems like a hose is placed into a kettle, and the pump is in the machine.
