Dražice OKC 160

Product detailed description

Combined vertical wall-mounted water heater, boiler Dražice OKC 160 for water heating

• Combined storage water heater designed for vertical wall mounting with a volume of 75 l.
• Domestic hot water preparation for buildings with hot-water central heating on gas or solid fuels during the winter season.
• Heating by electric energy outside the heating season, with the option of using a low electricity tariff (night current).
• Heating options:
  • By electric energy:
  • Heating is provided by a ceramic heating element controlled by an operating thermostat and protected by a safety thermostat (thermal fuse).
  • During heating, the ceramic element is controlled by a thermostat which allows continuous setting of the desired temperature (in the range of 5 to 74 °C).
  • By heat exchanger:
  • In combined water heaters, a heat exchanger is welded into the pressure vessel.
  • This heat exchanger is intended only for the heating circuit.
  • The heater can be connected to an external hot-water heat source with a max. temperature of 110 °C.
• The heater tank is made of steel sheet and tested at an overpressure of 0.9 MPa.
• The inside of the tank is enamelled.
• We recommend using the product indoors with air temperature from +2 °C to 45 °C and relative humidity max. 80%.

Recommendations before wall mounting:

• The manufacturer has maintained the spacing of the anchor bolts throughout the entire production history for easy replacement of old heaters.
• Before installation it is necessary to check the load-bearing capacity of the wall and, depending on the type of masonry, choose a suitable anchoring material, or reinforce the wall if necessary.
• Install the water heater only in a vertical position so that the bottom edge of the heater is located at least 600 mm above the floor.
• Due to the various types of load-bearing masonry and the wide range of special anchoring materials available on the market, the manufacturer does not supply the heaters with this material.
• The anchoring system must be chosen individually, according to the conditions.
• We recommend entrusting the wall mounting and anchoring to a professional company.

Frequently Asked Questions

• What tank volume should I choose? A common consumption estimate is based on approximately 40-50 liters of hot water (at about 40-45 °C) per person per day for standard use (showering, washing); if bathing in a tub or with more bathrooms/outlets, a higher volume should be considered. When choosing, also take into account whether the tank will be heated by a high-output boiler (faster heating, smaller volume may suffice) or, for example, only by a solar system (where a larger volume is worthwhile for heat accumulation during the day).
• Can I connect this DRAŽICE tank to an existing boiler? In most cases yes, but you should check the compatibility of the hydraulic connection (dimensions and type of connections) and whether your boiler supports control of the tank heating (a temperature sensor in the tank and possibly a switching valve are required) - you can find these details in the technical parameters of the product, or our customer service can advise you.
• Where and how is the tank installed? The tank should be placed as close as possible to the heat source (boiler) to minimize heat losses in the connecting piping, while also leaving enough space around it for service access (anode replacement, safety valve inspection).
• Must the installation be done by a professional? We always recommend entrusting the hydraulic connection to the water supply and heat source, including the installation of a safety valve set to the correct pressure, to a heating engineer/plumber - an incorrectly installed or missing safety valve poses a safety risk.
