User’s guide to an Air-eau heat pump system
How the heat system works
The heat pump takes renewable energy from the
surrounding air and converts it into usable heat. For
every 1kW of electrical energy the heat pump uses it will
extract approximately 3kW of energy from the outside air
making it 400% efficient which reduces carbon emissions
and money off your fuel bills!
How to operate your system efficiently
To operate the system in the most efficient way:
 Keep the room temperature as low as possible
and turn the heating to set back when the
property is not occupied.
 If the property has an off-peak tariff check with
your installer that they have set the DHW
recovery and sterilisation to happen during off-
peak times.
 Store the domestic hot water at a lower enough
temperature so the immersion is not required to
heat the Domestic hot water.
Keep power to the unit
The power should never be turned off except for
maintenance since the water in the external parts of the
heat pump are liable to freezing during cold weather. This
would lead to permanent irreparable damage to the heat
pump.
The heat pump is designed to operate extremely
efficiently all the time and should not be turned off at
night time, over summer or when you are away from the
house.
System health check
Your installer should have left you with a log book that
contains all the information required for your annual
system health check. If this is missing please contact
Dimplex customer care.
What to do if your system stops working
If anything goes wrong with the heat pump you should try
to solve the problem using the trouble shooting guide
below. If this is not successful you should contact
Dimplex customer care for technical support over the
phone. If the problem cannot be resolved over the phone
you should contact your installer.

Check the heat pump controller:
 Ensure the green light is on.
 Check for an error number and
contact your installer.
Heat pump
outside drips
water or emits
steam
This is a normal process during
cooler weather and is nothing to
worry about.
The amount of heat that the system can
output is closely matched to the maximum
load of the property. For this reason, the if
the blue button is pressed on the Central
heating controller you should be aware it
will take a long time to recover the room
temperature from a cold start, especially
during periods of extremely cold weather.
