REGULUS - R2GC storage water heaters - www.regulus.eu
4 - Operation
This tank is designed for operation in pressure circuits. Water can be heated inside in its heat exchangers
(heating coils) from several heat sources, e.g. various hot-water boilers, renewable energy sources (heat
pumps, solar collectors). An electric heating rod can be installed to backup DHW as well.
DHW temperature inside the tank shall be kept between 60 and 65 °C. This temperature guarantees optimum
operation and the best protection against Legionella bacteria.
