and in the respective assembly instructions for the ac-
cessories used. See page 62 for a list of the accessories
that can be used with F370.
Extra hot water heaters
Extra hot water heaters
The heat pump should be supplemented with an elec-
tric water heater, if a hot tub or other significant con-
sumer of hot water is installed.
Water heater with immersion heater
If it is possible to use a water heater with an immersion
heater, NIBE COMPACT or EMINENT type water heaters
can be used.
If the valve connector is to be installed externally,
moved out or separated, it must be replaced with a
separable connector Ø 22 mm.

Two or more climate systems
When more than one climate system is to be heated,
the following connection can be used.
The ECS 40/ECS 41 accessory is required for this con-
nection.
Connecting hot water circulation
To reduce the risk of bacterial growth in systems with
hot water circulation, the temperature of the circulating
water should not fall below 50 °C. There should not be
any non-circulatory hot water pipes. Adjust the hot
water system so that the temperature does not fall
below 50 ｰC at the extremities of the system.
The circulation pump for hot water circulation can be
controlled by the heat pump. The HWC return can be
connected to a freestanding water heater.
