Hottap is activated by water pressure. Before you have water flowing, or if you don't have enough flow (or pressure), nothing will happen. As in, HOTTAP won't make any sounds and the LED won't light up. Note: You can troubleshoot this issue by pressing and holding the 'Joolca' Icon on the LED screen and observing if the water flow error icon illuminates - read more Troubleshooting HOTTAP v2
As the water flows through HOTTAP, a sensor picks up the water flow rate and opens a gas solenoid valve, which allows the gas to flow into the burners and ignite. At this point, you'll hear a loud clunk (solenoid opening) and fast ticking (the ignitor).
This whole ignition system is powered by the two d-cell batteries. They are also what power up the LED screen. Because juice is only drawn when HOTTAP is active (and not much power is taken anyway) they last for quite a while. Normally at least 6 months, but it depends on your usage.
Once the HOTTAP is active, you can look through the slits above the control dials to see the flame. Adjusting the flame toggle will increase or decrease the size of the flame and thus the heat output. Adjusting your water will either reduce or increase the speed at which the water flows through the heat exchanged. Faster flow = less time to absorb heat, therefore less hot water. Slower flow, hotter water.
If you're using our 12V pump, that runs off a separate 12V power supply, namely a cigarette socket or any other 12V supply that you might have. Our pumps have a sensor which can tell when the water flow has been turned on / off.
What this means for you is that you can have your shower or faucet all set up, and by simply flicking the water flow on, the whole system will work automatically to start the water flow and heat the water up. When you're done, that same switch will shut everything off.

Setting up HOTTAP
Before setting up, please note that Hottap requires a water pressure of at least 70kPa to work. This part of the guide assumes that you have access to mains water.
For use with the Off-Grid Plumbing kit, please refer to pages 20-21.
To set up your Hottap for use, please cover the following steps:
Install 2 D-cell batteries observing the labelling on the battery box and the batteries.
Using a spanner, connect the female GasKnect fitting to the gas hose.
Do not use thread tape
Connect the regulator to the gas bottle and the GasKnect to the Hottap unit.
The gas cylinder must be positioned away and to the side of the appliance. It must never be directly beside, below or above the appliance.
When mounting your Hottap, please ensure that there is sufficient clearance from people and combustible materials: at least 1,000mm from the top, 600mm at the rear and at least 500mm from the sides and front of the unit.
Depending on what particular Hottap kit you own, you may mount it in one of three ways:
3.a. Heavy-duty stand Connect all hoses (see point 4.) and place unit into the heavy-duty stand.
3.b. Hang the Hottap on a suitable vertical surface
3.c. Lightweight legs Fasten the lightweight feet with the captive thumb screws.
Attach the red shower hose to the red quick connect fitting.
Connect the blue hose to your water source and to the blue quick-connect fitting on the Hottap.
Attach the GasKnect brass fitting to the gas inlet.
Connect the regulator to the gas cylinder. Open the gas cylinder by twisting the valve knob in an anti-clockwise direction one full turn.
Check the entire gas line for leaks by coating the hose and connection points with soapy water. Do not use a flame. If bubbles are formed or you can hear a leak, turn off the gas at the cylinder. Tighten all connections and test again.
Once you have determined that there are no leaks, the appliance is ready to use.
Turn the gas off.

- Remove the red plugs from the inlet and outlet of the pump.
- Snap the hoses onto the quick-connect fittings on the water inlet and outlet.
- Set up your filter for intended use - i.e. with or without the intake collar - and attach to end of pump inlet hose. Drop or throw filter into water source.
- Observing the flow direction of the pump, attach the pump outlet hose to the blue quick-connect fitting on the Hottap.
- Plug the lighter port cable into the pump and connect to power.
- Press the power button on the pump, leaving it in the “on” position. You can now start and stop the pump (as well as the Hottap) simply by flicking the switch on the shower or faucet handle.
In the US, the most common style of garden hose comes with 3/4" threaded fittings for the connections. To connect this to the HOTTAP you'll need to purchase an adapter, there are two options and both are widely available at your local hardware store:
The simplest method is remove the blue water inlet quick-connector and attach an adapter to allow for a direct connection with your garden hose.
A suitable adapter is something like this one and the water inlet will now look like this. Note: use thread tape for a secure and watertight fit.
This option is better if you'd like to keep the 'quick connect' features across the whole system.
Using any standard garden hose with typical 3/4" Threaded connections, you can purchase an adapter kit which will convert both ends of your hose to a quick connect, allowing you to connect directly to the HOTTAP water inlet, as well as using to extend the reach of your pump.
Something like this will work well, but any similar brand will also work.
If you'd haven't already done so, we recommend reading the quick 'set up' guide for HOTTAP v2 by clicking here
Ensure that the shower handle switch is in the “off” position.
Turn the gas on by twisting the cylinder valve knob in an anti-clockwise direction one full turn.
Open the valve at your water source. Please note that, since the shower handle switch is in the “off” position, water should not be flowing through the showerhead
You can now control the entire system at the shower handle switch. Flick it on: the water starts to flow and the Hottap burner automatically ignites. Flick it off: the water flow stops and the Hottap burner automatically extinguishes.
Bearing in mind that the water might be very hot, stand clear of the shower when turning it on.
Step 5) Setting your temperature
Adjust the red flame lever and the blue water flow dial to find your desired temperature and flow rate.
For higher temperatures, turn the flame up and the water flow down.
For lower temperatures, turn the flame down and the water flow up.

Does it handle rough roads and corrugations?
The HOTTAP is built to be robust and handles off-road conditions and corrugated roads with no trouble. At this stage, there are many HOTTAP units sitting on camper trailer drawbars and toolboxes travelling all over.
Are there any safety concerns?
The most important thing to remember is that the HOTTAP is not able to be permanently connected to a reticulated gas supply. What this means essentially is that it's OK for your HOTTAP to be fixed or mounted to your vehicle, but the gas connection should be made each time you set up and it must be disconnected before travelling again.
It's also important to comply with the clearance instructions listed at the back of the unit while in use.
Other ways to mount your HOTTAP
Using a TV mount allows you to conveniently store or swivel out to use when needed.
Compartmentalize your HOTTAP by bolting it to drawer slides.
