Heat Pump Water Heater Installation Guide
NOTE:
If the heat pump is connected to an off peak power supply or
‘ripple control’, power may not be available at certain times of the day. We
recommend temporarily running a mains supply to the main isolator to allow
testing of the heat pump water heater in this case.
• After an 8 minute delay unit will start. The status light will glow solid red.
• The unit will preheat the water to 60°C which takes 3-5 minutes, then the
hot water outlet connection will be hot to the touch.
• (If available). Check that the unit has reached 60°C on the Econergy
®
installation software and the flow has stabilized.
• The unit will now heat the whole tank from the top down until the return
temperature is 50°C.
• Tidy up installation.
• If there is time then check that the whole tank has heated successfully
otherwise check back later and use the Econergy
®
Config software to
download the events log to ensure that the unit is operating as expected.
Troubleshooting
If the Econergy
®
water heating system is not working correctly as per the
commissioning instructions above, please refer to the following troubleshooting
information.
Symptom
Possible Cause
Things to Check
Unit is not
heating
a) Isolation valves

Close isolation valve going from water
heater unit into top of HWC. Slacken
fitting on outlet of water heater and
purge for a minute or so. Close fitting,
open valve and restart unit.
c) heat pump has
