General
Principle of operation
VVM 300 is an electric boiler designed for houses with wa-
ter borne heating. It consists of a double jacketed pressure
vessel, two immersion heaters and advanced controls.
The total water volume is 280 litres, of which 125 litres are
in the double jacketed space and 155 litres in the heater.
The hot water heater has a copper lining to protect against
corrosion. The immersion heaters are in the double jacket.
The immersion heaters have a max output of 13.5 kW
with option of setting lower outputs. The factory setting is
9.0 kW.
The charge pump in VVM 300 is speed controlled and ad-
justs the charge flow automatically.
VVM 300 is equipped with climate controlled automatic
by-passes to maintain the correct temperature for the
heating system. This temperature is determined by the ac-
tual outdoor temperature and selected basic settings.
VVM 300 is designed for connection and communication
with FIGHTER 2020. Sizes 8 and 10 can be connected.
FIGHTER 2020 and VVM 300 together make up a com-
plete heating plant.
FIGHTER 2020 covers the entire heating and hot water
requirement until the output requirement of the house
exceeds the specified heat pump output. In the tempera-
ture zone between balance temperature and stop tem-
perature, FIGHTER 2020 works together with VVM 300. If
the outdoor air temperature drops down to a level below
the stop temperature for FIGHTER 2020, all heating occurs
with VVM 300.
