Frequently Asked Questions

• What tank volume should I choose? A common consumption estimate is around 40–50 litres of hot water (at approx. 40–45 °C) per person per day for standard use (showering, washing); if you take baths or have several bathrooms/outlets, you should plan for a larger volume. When choosing, also consider whether the tank will be heated by a high-output boiler (faster heating, so a smaller volume may be enough) or, for example, only by a solar system (where a larger volume is actually beneficial for storing heat accumulated during the day).
• Can I connect this BUDERUS tank to my existing boiler? In most cases yes, but you should check 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 required) — you will find these details in the product’s technical parameters, or our customer service can advise you.
• Where and how should the tank be installed? The tank should be placed as close as possible to the heat source (the boiler) to minimise heat losses in the connecting pipework, while still leaving enough space around it for service access (anode replacement, safety valve inspection).
• Does the installation have to be done by a professional? We always recommend leaving the hydraulic connection to the water supply and to the heat source, including fitting the safety valve at the correct pressure, to a qualified heating engineer/plumber — an incorrectly fitted or missing safety valve is a safety hazard.
