REMKO WKF 85 - Manual (Page 35)

3.2 WKF series
We offer two different indoor-unit designs. The
wall-mounted WKF series is equipped with a circu-
lation pump and a safety module on the water side.
Furthermore, an electrical auxillary heater can be
incorporated as an option. It may be dispensed
with an external buffer tank when the heat pump
acting as the sole heat source. Should a second
heat source may be used, a buffer tank is needed.
The WKF series was constructed for the addition of
several heat sources (bivalent installations or sys-
tems with solar-heating equipment).
External buffer tank is always required, its size
depending on the type and the power of the
second heat source. On the one hand, the buffer
tank prevents short run-times for the heat pump
and on the other hand, that sufficient defrosting
energy is available.
3.3 WKF-compact series
In addition, the indoor module of the WKF-compact
series is fitted with an enamelled 300 L domestic
water storage. An auxiliary electric heater 9 kW is
available optionally. As a result, the WKF-compact
series is the ideal equipment when the heat pump
is intended as the sole heat source (single energy-
source operation).
Single energy-source operation by REMKO Smart-
Serv or bivalent operation by REMKO Smart-BVT
is also to realize. All connections are to be installed
on top of the device.
