Frequently Asked Questions

• Which storage tank volume should I choose? A typical consumption estimate is based on approx. 40-50 litres of hot water (at approx. 40-45 °C) per person per day for standard use (showering, washing); if bathing in a tub or having more bathrooms/outlets, a larger volume should be considered. When choosing, also take into account whether the tank will be heated by a high-output boiler (faster heating, a smaller volume may suffice) or, for example, only by a solar system (where, on the contrary, 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 verify the compatibility of the hydraulic connection (dimensions and type of fittings) and whether your boiler supports control of the tank heating (a temperature sensor in the tank and possibly a switching valve are needed) - you can find these details in the product's technical parameters or our customer service will advise you.
• Where and how is the tank placed? The tank should be placed as close as possible to the heat source (boiler) to minimise heat losses in the connecting pipework, while still 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 fitting the safety valve set to the correct pressure, to a heating engineer/plumber - an incorrectly fitted or missing safety valve poses a safety risk.
