REGULUS - R2GC storage water heaters - www.regulus.eu
1 - Description
R2GC storage water heater (“tank” further on) is designed to accumulate heat for domestic hot water (DHW).
The tank is heated from hot-water heat exchangers installed inside (2 heating coils). The lower heating coil
can be used to connect e.g. a solar system while the upper heating coil can be fed from e.g. a gas-
fi
red boiler
or an accumulation tank. The speed of heating up the tank to the desired temperature depends primarily on
the
fl
uid temperature entering the heat exchanger. Higher temperatures of the incoming
fl
uid mean quicker
heating up the tank, and vice versa. Should the output of the heat exchanger be insuf
fi
cient for some applica-
tions, an electric heating rod can be installed into the tank.
The entire hydraulics of a heating system shall be designed properly in order to achieve
fl
awless operation of
the tank, i.e. the position of circulation pumps for heat sources and heating circuits, valves, check valves etc.
1.1 - Model line
These storage water heaters are supplied in four sizes: 200, 250, 300 and 400 l.
1.2 - Tank protection
The tank body is made of sheet steel,
fi
nished outside with durable ecologic powder coating. Its inner enamel
lining works as anticorrosion protection and together with a magnesium anode rod it guarantees a long serv-
ice life. The magnesium anode rod shall be inspected regularly - see point 7. Maintenance, Replacement of
Magnesium Anode Rod. An electronic anode can be also used; its lifetime covers the lifetime of the tank if its
operation indicator works right.
1.3 - Thermal insulation
Tanks are insulated with ecologic 55 mm PUR foam (50 mm for R2GC 400) that reduces thermal loss to mini-
mum.
1.4 - Connection points
4× lateral, G 1“ female thread, for heating coils
2× lateral, G 1“ female thread, cold water in, hot water out
2× lateral, G 1/2“ female thread, for temperature probes
1× lateral, G 3/4“ female thread, for recirculation
1× upper, G 5/4“, for magnesium anode rod
1× lateral, G 6/4“ female thread, for electric heating rod
1× lateral, G 1/2“ female thread, for thermometer
1.5 - Packing
Tanks are delivered standing, each screwed to its pallet, shrink-wrapped. It is forbidden to transport and/or
store the storage tanks in a horizontal position.
2 - General Info
The appliance shall be installed by a quali
fi
ed person according to valid rules.
