1 - Description

R2BC Storage water heater (further “tank“) with two enameled heating coils with G 5/4” connections (e.g. for

connecting a solar system and a heat pump), enabling installation of an electric heating element and also an-

other el. heating element or a ﬁnned tube heat exchanger into the ﬂange of the lateral inspection hole.

In order to reach proper working of the tank, it is necessary to design optimum hydraulics of the whole system,

i.e. position of circulation pumps for sources and heating circuits, valves, non-return valves etc.

1.1 - Models

Ten models of 200, 300, 400, 500, 750, 1000, 1500, 2000, 2500 and 3000 l capacity enabling installation of an

electric heating rod or another heat source.

1.2 - Tank protection

Enameled inner surface and coil guarantee long service life. Enamel is done according to DIN 4753 standard.

Further qualitative improvement is reached thanks to a magnesium anode installed inside the tank. From the

volume of 400 l upwards each tank has 2 anode rods. The 3000l tank has 3 anodes.

1.3 - Thermal insulation

Tanks of volume up to 500 l are supplied with a hard polyurethane insulation 50 mm thick with a white PVC

surface. Tanks of 750 and 1000 l volume are supplied with a hard polyurethane insulation 75 mm thick with

a white leatherette surface. Tanks of 1500, 2000, 2500 and 3000 l volume have the insulation 100 mm thick.

The insulation can be detached for easier handling.

1.4 - Connection points on the tank

4× lateral with G 5/4“ inner thread, to the heating coils

2× lateral with G 5/4“ inner thread, for cold water inlet and hot water outlet

3× lateral with G 1/2“ inner thread, for temperature probes and a thermometer

1× lateral with G 1“ inner thread, for recirculation

1× top with G 5/4“ inner thread, for a magnesium anode rod

1× lateral with G 6/4“ inner thread, for an el. heating rod

1× ﬂange for the lateral inspection hole

1.5 - Packing

Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap. It is forbidden to transport

and/or store the storage tanks in a horizontal position.
