HOTTAP Lights but but can only stay on with 'LO' Water Flow:
If you find the Hottap works well on LO but then turns off when you adjust water flow upwards, the problem will be with your water supply. Try these things:
- Check for blockages in your water lines. Unscrew your blue quick connect adaptor on the water inlet, and look inside the brass inlet fitting to make sure the mesh is clear. Make sure to clean the inline filter on your pump also if you have it.
- If you're aren't using a Joolca pump, then make sure your pump matches the specs below:
- Flow rate between 6-12 LPM
- Pressure between 45-65 PSI
- Try the Hottap on mains water. If it works fine you can work backwards to figure out what is restricting the flow to the Hottap.
HOTTAP lights up (on any water flow) but later turns off:
Reaching Cut-off Temperature
Make sure the unit is not exceeding 50 degrees Celsius otherwise the flame will cut out
automatically, this is to prevent scalding.
- Turn water flow HI and/or turn the gas dial LO. This will reduce the temperature of the water, helping it stay under 50 degrees Celsius.
Wind Related Issues
The HOTTAP has a flame sensor as a safety component. This is designed to shut off gas supply to HOTTAP as soon as it notices that the flame has been extinguished. What wind does is act to push the flame sideways or stretch it upwards which simulates a 'flame out' and causes the safety circuit to kick in.
There are a few things we can do to remedy this, try the below:
- The default position of the top vent has louvres that are facing into the unit, which can in effect 'catch' the wind and send it down into the Hottap. By removing the 4x screws on each corner and flipping the grill upside down, we'll make the louvres face upwards and help to direct any oncoming wind 'up and away' from the unit.
- Blocking the side ventilation holes can help to reduce the wind effects. We have tested the unit and it does not hinder the performance in any way by blocking this vents totally (we've used aluminium tape).
- Building a box around the unit. Use sheet metal or something non-flammable. Make sure its adequately ventilated. Legal requirements are a 1m form the top and 50cm from sides, 0 from the back. (cant be near any combustible eg. gas bottles).
