WWK 300
the DHw heat pump wwK 300 is
a compact appliance for delivering
DHw at several draw-off points
in domestic and commercial
environments. infinitely variable DHw
temperature in heat pump operation,
from 25 °C to 55 °C of the total water
content. where required, the DHw
will be heated up automatically to
65 °C (electric reheating of 100 l)
via a programmable time switch
(7-day disc). As standard equipped
with a main isolator, thermometer,
illuminated pushbutton for heating
once-only (100 l to 65 °C) and
switch for constant operation via
electric booster heater. the compact
appliance comprises the following:
Air | water heat pump unit with
condenser, evaporator, fan and
compressor. Also, steel DHw cylinder
(with special enamel coating on
the inside) with anti-corrosion rod,
electric booster heater, CFC-free
thermal insulation offering low heat
losses, plus all control and switching
facilities. the metal casing is stove
enamelled in white and is fully
wired.
WWK 300 SOL
the DHw heat pump wwK 300
sol with integral indirect coil for
connection to a solar thermal system
of a boiler is a compact appliance for
delivering DHw at several draw-off
points in domestic and commercial
environments. infinitely variable
DHw temperature in heat pump
or boiler operation, from 25 °C to
55 °C of the total water content.
where required, the DHw will be
heated up automatically to 65 °C
(electric reheating of 100 l) via a
programmable time switch (7-day
disc). As standard equipped with a
main isolator, thermometer, boiler
operation pushbutton (total contents
up to 55 °C), illuminated pushbutton
for heating once-only (100 l to 65
°C) and electric booster heater.
Air | water heat pump unit with
safety heat exchanger (condenser),
evaporator, fan and compressor. Also,
steel DHw cylinder (with special
enamel coating on the inside) with
anti-corrosion rod, electric booster
heater and heat exchanger for
boiler operation, CFC-free thermal
insulation offering low heat losses,
plus all control and switching
facilities. the metal casing is stove
enamelled in white and is fully
wired.
