8. Maintenance 

 

DO I NEED TO GET MY UNIT 

SERVICED? 

It is recommended that you get your EvoHeat unit serviced once a year by 

your local certified air conditioning or refrigeration technician. If your unit is 

located in a coastal area, more frequent maintenance may be necessary. 

During the service, they will check the operational pressures of the 

refrigeration system and give the unit and fins a good clean to ensure 

maximum performance. 

 

DO WE HAVE RECOMMENDED 

SERVICE AGENTS? 

EvoHeat have a large database of recommended service agents. Please 

contact EvoHeat tech support on 1300 859 933 for your local service agent 

details. 

 

SHOULD I CHECK MY UNIT 

REGULARLY? 

We recommend you check your unit regularly to avoid potential issues and 

damage to your heat pump. 

 

WHAT SHOULD I BE CHECKING 

REGULARLY? 

Check the water inlet/outlets often for leaks. You should avoid the condition 

of no water or air entering into the system, as this will influence unit’s 

performance and reliability. 

 

 

The area around the unit should be dry, clean and well ventilated. Make sure 

there is nothing blocking the airflow of the heater e.g. Leaf litter. Clean the 

heat exchanger every few months to keep a good heat exchange rate and 

save energy. 

 

You should discharge the water at the bottom of the water pump if the unit 

will not be used for an extended period. Discharge all water in the water 

pump and water system so that freezing of the water in the pump or water 

system does not occur. Check the unit thoroughly and fill the system with 

water fully before using it for the first time after a period of time. 

 

Check the power supply and cable connection often, should the unit begin to 

operate abnormally, switch it off and contact the qualified technician 

 

Clean the water filter periodically to maintain good water quality. Lack of 

water and dirty water can damage the unit. The heat pump will start the water 

every 72 hours when it is not running to avoid freezing. 

 

The water loop of the heat pump MUST be protected from freezing in winter. 

Do not shut off the power supply to the heat pump in winter. When the air 

temperature is below 0°C, if the inlet water temperature is above 2°C and 

below 4°C the water pump will begin freezing protection. If the inlet water is 

lower than 2°C, the heat pump will begin heating.
