The HOTTAP needs to be used with mains water, a pump, or another pressurised water source. The HOTTAP unit itself does not have the ability to draw water from a source.
The HOTTAP needs a pressurised water source in order to work. Basically, you need to be 'pushing' water into the HOTTAP, in order for it to turn on.
Well, you still need batteries and gas: and you can find more info here.
What does this mean
The HOTTAP needs a way to turn on and off automatically. This way you don't need to stand near the unit and keep flicking a switch. To do this, the HOTTAP has a way of sensing water flow. And so that it runs safely and smoothly, it needs a minimum amount of water flow (otherwise it would be on all the time).
The HOTTAP needs a minimum of 6 litres/min and 10 PSI to work on the maximum flow setting. The maximum flow setting is having the water dial set to max, where we have the most water flow.
Imagine having a crowd of people leaving an empty room, through one walkway. We need to have 6 people walking out of the room at one time—this is the water flow. And we can't just have them walk, oh no, we need them to jog. So we give them a little nudge—this is the water pressure.
And there you go, we have enough water flow and pressure.
Thankfully, we have a few ways of doing this.
Which water supplies will work
All of these will work.
The Joolca FLOTAP pump
Of course. This is how the setup looks.
A pressure pump with 6 litres/ min and 10 PSI to work on all the water flows.
- Just like the room analogy. If we only have a 4 litre/ min pump—or only 4 people leaving the room at a time—well since 4 is less than 6, we can't use the max water setting. Although, we can still turn the HOTTAP on. We'll only be able to use the middle setting. Any higher and the unit will turn off.

- Will my existing pump work?
A garden tap
- If you're using council mains (in a domestic area), all good.
- If you're on an off-grid property and have your own 'local' water supply, this should work. Although, if you have a super high flow pump (eg. 50+ litres/ min) and super low pressure (less than 10PSI), this could be an issue. It's like now trying to push 50 people at a time out of that same 6 person walkway. People will stumble and fall. And after all the havoc, you might only have a handful of people leaving at a time. And with not enough force. If you have issues with this setup, we recommend another pump.
