FAQs
What is the maximum number of outlets the Zip Cex-O can supply?
The Zip Cex-O is designed for one or more outlets at a single point of use, such as a sink. It is not intended for multiple, simultaneous uses across different rooms.
Does this water heater require a storage tank?
No, the Zip Cex-O is an instantaneous water heater, meaning it heats water on demand as it flows through the unit. It does not have a storage tank.
What electrical supply is needed for this unit?
This unit requires a dedicated, high-power electrical circuit. The specific power rating (6.6kW-8.8kW) dictates the required amperage and wiring size. Professional installation by a qualified electrician is mandatory.
How do I adjust the power output?
The power output (6.6kW or 8.8kW) is typically adjusted via an internal switch during installation by a qualified technician, based on the available electrical supply and hot water requirements.
What is the flow rate of hot water?
The flow rate is dependent on the selected power output and the incoming water temperature. At 8.8kW, it provides a higher flow rate of hot water compared to 6.6kW. Consult the product manual for specific flow rate charts at different temperatures and power settings.
Is professional installation required?
Yes, due to the high electrical power requirements, professional installation by a qualified electrician and plumber is essential for safety and correct operation.
What is the warranty period?
The Zip Cex-O comes with a 1-year guarantee.
Troubleshooting
No hot water when tap is turned on.
Check that the power supply to the unit is switched on at the circuit breaker. Ensure the water supply to the unit is open. Verify that the unit has not been switched off at its isolation switch. If problems persist, check for airlocks or blockages.
Water is not hot enough.
Confirm the unit is set to the higher power output (8.8kW) if available and required. Check incoming water temperature; colder inlet temperatures will result in lower outlet temperatures at a given flow rate. Ensure the flow rate is not too high for the selected power setting. Check for any potential scaling or sediment buildup.
Low water flow from the outlet.
Check the aerator or outlet nozzle for blockages or limescale. Ensure the cold water supply pressure is adequate. Inspect inlet and outlet hoses/pipes for kinks or restrictions.
Unit is making unusual noises.
Some minor gurgling or expansion noises can be normal. Loud banging or hissing could indicate an issue with water flow or pressure. Turn off the unit and consult the installation manual or a professional.
Pros and Cons
Pros
- Provides unlimited hot water as long as the unit is powered.
- Highly energy-efficient due to no stored water and heating only when required.
- Space-saving design, ideal for locations with limited room.
- Fast heat-up time.
- Adjustable power settings offer flexibility.
Cons
- Requires a dedicated high-power electrical circuit, which may necessitate electrical upgrades.
- Maximum flow rate is limited by the unit's power output.
- Not suitable for whole-house hot water solutions.
- Installation requires professional electrical and plumbing expertise.
- Initial power draw can be high.
Setup, Compatibility & Care
Setup:
- Electrical Connection: The Cex-O requires a dedicated, high-power electrical circuit. Consult a qualified electrician to ensure your home's wiring can support the unit's load (6.6kW to 8.8kW). A specific circuit breaker and appropriate gauge wiring are essential.
- Plumbing Connection: Connect the unit to the cold water supply using standard plumbing fittings. Ensure all connections are secure to prevent leaks.
- Power Setting: Select the desired power output (6.6kW or 8.8kW) by adjusting the internal switch as per the installation manual. This should be done by a qualified installer.
- First Use: Once installed, turn on the cold water supply and allow water to flow through the heater for a minute before switching on the power to prevent dry firing the heating elements.
Compatibility:
- This unit is designed for single-point-of-use applications, such as sinks, basins, or light commercial washing stations.
- It is not designed to replace a whole-house hot water system.
- Requires a mains cold water supply.
Care:
- Cleaning: The exterior casing can be cleaned with a soft, damp cloth. Avoid abrasive cleaners that could damage the finish.
- Maintenance: Periodically check water connections for leaks. The unit is designed for low maintenance, but regular inspection ensures optimal performance. The heating elements are self-regulating and do not typically require user maintenance.
- Scale Buildup: In hard water areas, scale can form over time. While the bare wire elements are more resistant, professional servicing might be required if flow or temperature issues arise.
