FAQs
What is an 'unvented' water heater?
An unvented water heater is a system that operates directly from the cold water mains supply pressure, meaning it doesn't require a separate cold water storage cistern. This often results in higher water pressure and flow rates at the tap.
Do I need a special type of plumber to install this?
Yes, due to the nature of unvented systems, installation must be carried out by a qualified and registered installer who is certified to work on unvented hot water appliances.
How often should the unit be serviced?
It is recommended to have the unit and its safety devices inspected and serviced annually by a qualified professional to ensure continued safe and efficient operation.
Can this unit supply more than one tap?
The 10-litre model is typically designed for single-point-of-use applications. While it might supply a very low-demand second point intermittently, it is not recommended for simultaneous use on multiple outlets.
What is the role of the manually resettable over temperature safety cut-out?
This is a crucial safety device that automatically cuts power to the heating element if the water temperature exceeds a safe limit. It must be manually reset after activation, which usually involves cooling the unit and pressing a reset button.
How do I adjust the water temperature?
The Zip Aquapoint III features an external temperature control dial. Simply turn the dial to your desired temperature setting. Allow a short period for the water to reach the new temperature.
What maintenance is required for frost protection?
The frost protection system operates automatically. However, ensure the unit is installed in a location that is adequately protected from freezing, and consider having a professional check its functionality during annual servicing.
Troubleshooting
No hot water or insufficient hot water.
Check the power supply and ensure the circuit breaker is not tripped. Verify that the temperature control is set correctly. Inspect for any obvious blockages in the water inlet or outlet. If the over-temperature safety cut-out has activated, allow the unit to cool and manually reset it. If the problem persists, contact a qualified engineer.
Water is too hot or too cold.
Adjust the external temperature control dial to the desired setting. Allow a few minutes for the temperature to stabilize. If the temperature remains incorrect, the thermostat may require recalibration by a professional.
Unit is making unusual noises.
Rumbling or banging noises can sometimes indicate scale build-up. If the noises are persistent or concerning, it is advisable to have the unit inspected by a qualified engineer.
Water leaking from the unit.
Immediately turn off the water supply to the unit and contact a qualified plumber. Do not attempt to use the unit until the leak has been repaired.
Frost protection indicator shows activation.
This indicates low ambient temperatures. Ensure the unit is installed in an area where it is protected from freezing conditions. The frost protection should automatically deactivate once the ambient temperature rises. If it remains active or causes concern, consult the installation manual or a qualified engineer.
