3 Design and function
3.1 Domestic hot water heat pump,
general
Arguments in favour of the domestic hot water
heat pump from REMKO
n Hot water heat pump with advanced tech-
nology guarantees optimum and extremely
quiet operation.
n The powerful radial fan enables air guidance in
pipe lengths up to 12 m with Ø 150 mm.
n The thermostatic expansion valve and the
safety devices ensure optimum circuit function-
ality.
n The heart of the hot water heat pump: The
strong and durable condenser with oil cooler
and waste heat utilisation through suction gas
cooling.
n Large-area finned evaporator.
n The air connections enable a simple supply/
exhaust air installation at the assembly site.
n Environmentally friendly and non-flammable
safety refrigerant R134A.
n Enamelled quality hot water tank. Quality
assurance guarantees a long service life, sacri-
ficial false anode for increased safety.
n Tube coil condenser ensures efficient heat
transfer and optimum safety.
n Internal smooth tube heat exchanger for the
connection of solar collectors or boilers.
n Electric heater, factory installed.
n Negligible maintenance costs.
Function of the hot water heat pump
The hot water heat pump utilises ambient air for
hot water preparation. The air is drawn in from
above with the aid of a fan, supplied to the evapo-
rator and subsequently blown out again at the top.
The evaporator is so-called, because it evaporates
the refrigerant in the heat pump circuit. During
evaporation, heat is taken from the ambient air
drawn in, because this is warmer than the refrig-
erant in the evaporator. This means that heat can
be obtained from the air and transferred to the
refrigerant even at relatively low temperatures. The
refrigerant is compressed by the condenser, and
brought to a higher temperature level. This heat is
transferred to the drinking water via the tube coil
condenser. The cooled refrigerant, which is once
again liquid in state, is expanded in the expansion
valve, transported to the evaporator and is there-
fore able to absorb heat once again.
The refrigerant circuit
The hot water heat pump operates according to
the Carnot process. The refrigerant circuit is filled
with refrigerant R134a in the factory, is highly effi-
cient and guarantees optimum safety and effi-
ciency in operation.
3.2 Product description
The Remko RBW 300 is a domestic hot water heat
pump with integrated enamelled hot water storage
tank. The storage tank has a volumetric capacity of
300 l and is therefore sufficient for the larger
family. The RBW 300 is easy to install due to the
practical pipe connections and plug-in electric
wiring, e.g. in the basement, plant room or utility
room.
The Remko RBW 300 S is a domestic hot water
heat pump with an additionally integrated heat
exchanger with 1.5m
2 , for the connection of a solar
plant or another heat generator.
During pure heat pump operation, the max.
drinking water temperature is 60 °C. This means
that a high level of drinking water hygiene can be
guaranteed. With an increased demand for hot
water or high temperatures, it is possible to actuate
the 1.5 kW electric heating element.
3.3 Corrosion protection
The hot water tank is produced from enamelled
steel. This is designed for standard quality drinking
water. If drinking water with above-average
aggressive qualities is used (chloride content ³ 150
mg/l) then it is not possible to provide a guarantee
unless special protective measures are imple-
mented.
NOTICE!
Check the false anode regularly and have this
replaced by your fitter if necessary. This is a
prerequisite for the guarantee!
NOTICE!
It is essential to replace the magnesium-false
anode if this exhibits a diameter of just 6-10
mm!
