Maintenance
Your Evo270-1 will operate most efficiently if regularly inspected as part of your home maintenance schedule.
ANNUAL MAINTENANCE
It is recommended that the minor maintenance be performed every 12 months by the dwelling occupant.
The minor maintenance includes:
- Operate the easing lever on the temperature pressure relief valve. It is very important you raise and lower the lever gently. Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot. Stand clear of the drain lines point of discharge when operating the valve’s lever.
- Operate the easing level on the expansion control valve (if fitted). It is very important you raise and lower the lever gently.
- Conduct a visual inspection of all plumbing and electrical connections.
- Check the condensate drain line to ensure it is not blocked.
- Check that air vents are not blocked or obstructed, and if necessary clean with a damp cloth or air blower.
- Conduct a general external clean of the unit with a damp cloth.
3-YEAR SERVICE
It is a warranty requirement that a three (3) year service must be conducted on the Evo270-1.
Just as a car needs regular servicing, your heat pump also requires a three-year service to maintain efficiency and ensure long-term performance.
Warning: Servicing of a water heater must only be carried out by qualified EvoHeat personnel. Phone EvoHeat Service on 1300 859 933 for our closest Accredited Service Agent.
Note: The three-year service and routine replacement of any components such as the anode and relief valve(s) are not included in the EvoHeat warranty. Only genuine replacement parts should be used on this water heater.
The major service includes the following actions:
- Replace the temperature limiting valve.
- Replace the temperature pressure relief valve.
- Inspect the anode and if required, replace the anode. If the anode is not replaced, it should be replaced within three years of this service.
- Check the heating cycle of the unit.
- Visually check the unit for any potential problems.
- Inspect the plumbing and electrical all connections.
- Check the condensate on drain line to ensure it is not blocked.
Note: The water heater may need to be drained during this service. After the completion of the service, the water heater will take some time to reheat the water. Depending upon the power supply connect on, hot water may not be available until the next day.
Energy Saving Tips
Use Eco Mode
When you switch on Eco Mode for your Evo270-1 heat pump, it saves energy by turning off the electric booster heater. This means the system heats water more efficiently, using less power overall while still providing the hot water you need. By relying solely on the heat pump’s efficient operation, you can significantly reduce electricity costs without compromising your hot water supply, making it a great option for everyday use when high water demand isn’t necessary.
Maintenance
Maintenance is key to keeping your EvoHeat hot water heat pump running efficiently, saving you energy and reducing costs. Simple care can ensure it performs at its best, minimising energy use and extending its lifespan for long-term savings and reliability. Refer to your product manual for specific maintenance tasks to maximise energy savings and extend the life of your system.
