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 another 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.

4 - Operation This tank is designed for operation in closed pressure circuits. Hot water is heated in the integrated hot-water heat exchangers (heating coils) inside the tank from several possible heat sources like various kinds of heating boilers, renewable energy sources (heat pumps, solar collectors). Hot water temperature should be set to 60-65 °C. This temperature guarantees the best operation and at the same time, it prevents formation of Legionella bacteria.

Table of limit values for total dissolved solids in hot water Description pH Total dissolved solids (TDS) Ca Chlorides Mg Na Fe Max. value 6.5 - 9.5 600 mg/l 40 mg/l 100 mg/l 20 mg/l 200 mg/l 0,2 mg/l 6 - Installation and Commissioning Installation must meet valid rules and may be done only by qualified staff. The tank shall be placed on the floor, as close to the heat source as possible. Defects caused by improper installation, use or handling are not covered by warranty. 6.
6.6 - Commissioning Fill the heating circuits with the appropriate fluids and air-bleed the entire system. Check all connections for leaks and verify the system pressure. The quality of top-up and heating water is set by ČSN 07 7401:1992. Hot water quality must meet the conditions shown in the Table of limit values for total dissolved solids in hot water, page 7 of this Manual. Fill the heating circuits with the appropriate fluids and air-bleed the entire system.
8 - Maintenance, Replacement of Magnesium Anode Rod If the tank is fitted with a heating element, disconnect it from the mains first. Clean the exterior of the tank with a soft cloth and a mild detergent. Never use abrasive cleaners or solvents. Check all connections for leaks. The tanks are equipped with an anti-corrosion sacrifice magnesium anode rod. The anode rod shall be checked within 12 months after commissioning and subsequently always not later than 12 months after the last check.
11.2 - Electric heating rods and a mounting flange for the inspection hole Electric heating rods can be used in storage water heaters and in accumulation tanks. They can be power supplied either by 230V or 3 × 230V/400V. Heating rods of output 2-12 kW can be installed into these tanks, into the sleeves with G 6/4” inner thread (the right type should be selected with respect to its length and the tank diameter). Electric heating rods are currently made of nickel-plated copper.
.3 - Tube heat exchangers and their mounting flange When needed, a finned tube heat exchanger may be installed into the appropriate flange (code 8375), into the lateral inspection hole instead of a plug.
