Emptying the hot water heater
The water heater is of the coil type and is drained using the
siphon principle. This can be done either via the drain valve on
the incoming cold water pipe or by inserting a hose into the
cold water connection.
Emptying the vessel
Contact your installer if the vessel in indoor unit needs emptying.
Maintenance of outdoor unit

however some exterior maintenance is still necessary.

Saving tips
Your Hydrolution produces heat and hot water according to
yourneeds.Italsoattemptstocarryoutallrequirementswith
all available “aids” from the control settings made.
The indoor temperature is naturally affected by the energy
consumption.Therefore, take care not to set a temperature
higher than necessary.
Otherknownfactorsthat affectthe energyconsumptionare,
for example, hot water consumption and the insulation level of
the house, as well as the level of comfort you require.
Maintenance
Also remember:
■ Open the thermostat valves completely (except in the
rooms thataretobekept coolerforvariousreasons,e.g.
bedrooms).
Thermostat valves in the radiators and floor loops can
negativelyaffecttheenergyconsumption.Theyslowtheow
in the heating system, which the heat pump wants to
compensatewithincreasedtemperatures.Itthenworksharder
and consumes more electrical energy.
