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.

Ali gre ta hranilnik fizično pod GB172 brez dodatnih podstavkov - torej, ali je višina 960 mm merjena tako, da obstaja dovolj prostora za priklop cevi na vrhu, ko kotel visi na steni nad njim?

Logalux S120/5W je narejen prav za to kombinacijo - je stacionarni hranilnik z majhno instalacijsko površino, zasnovan tako, da se namesti pod stenski plinski kotel, torej tudi pod GB172. Višina 960 mm je skupna višina hranilnika, priključki za cevi pa so spredaj/zgoraj dostopni, tako da pri montaži pod kotel ni posebnih ovir. Če te zanima natančna razporeditev priključkov, lahko pogledaš tehnično risbo pri izdelku ali nam pišeš po e-pošti, pa preverimo konkreten primer.

About the company 

Bosch Thermotechnology is one of the largest manufacturers of heating and hot water equipment in the world with a turnover of 3 billion euros. As a supplier of system solutions, Bosch Thermotechnology has set itself the goal of providing comfortable and cozy living conditions and hot water in an energy-saving and environmentally friendly manner.

Bosch Thermotechnology includes the international brands Bosch (which is the successor to the Junkers brand) and Buderus in the field of thermal technology. With a product portfolio covering wall-hung and stationary boilers, including heat pumps and combined heat and power units, through solar systems to flow-through hot water heaters, Bosch Thermotechnology offers prospective and energy-efficient solutions compatible with the environment.

Buderus

As few brands in the world can boast a history of more than 280 years, Buderus can. As early as 1731, Johann Wilhelm Buderus founded his foundry near Laubach in Upper Hesse.

In the past, Buderus boilers were imported into the Czechoslovak Republic through foreign trade companies, and thus these boilers ensure reliable heating and hot water in many important buildings, such as the Prague Congress Centre or the Ministry of Foreign Affairs of the Slovak Republic in Bratislava. No exception are also smaller capacity boilers in family homes, which have been operating for more than 25 years.

Further development of the company, which ultimately brings higher customer satisfaction, is supported by the fact that Buderus became part of the Bosch Group in 2004.

Buderus, as a system expert, offers comprehensive heating system solutions on the Slovak market for apartments, family homes, as well as medium and large buildings. The range includes heating equipment for natural gas, propane, as well as equipment using renewable energy sources. Buderus, as a supplier of complete heating systems, offers hot water storage heaters, heating bodies and controls for each type of system. For the customer, this means that they receive a complete system from one supplier.

At present, the Buderus brand is focusing on new advanced solutions that make more use of technologies using renewable energy sources. The efficiency, economy and environmental impact of using heat pumps or a combination of solar panels and a condensing gas boiler are very interesting options in new buildings and also when renovating older buildings.

All products offered meet the most modern ecological requirements and are designed with the aim of the most economical operation. Responsible planning and implementation of heating requires a responsible supplier: Robert Bosch s.r.o., Thermotechnology Division - Buderus is the right one.

History 

1731 - It all began with a high coal-fired furnace - in it, Johann Wilhelm Buderus I. produced cast iron, among other things, oven plates.

1835 - J.W. Buderus's company already had five foundries and produced stoves, which already meant comfortable heat at that time. Since then, Buderus has been setting trends in heating.

1881 - In the 19th century, Buderus gained an excellent reputation with its stoker stoves. These stoves were considered the most reliable and most efficient stoves on the market.

1898 - The first sectioned cast iron boilers were patented and the production of the first cast iron heating bodies (radiators) could be started.

1915 - Buderus attracted attention and admiration with the first large oil-fired boilers and in 1930 it was the first to produce a special oil-fired boiler.

1950 - Since the beginning of the 1950s, Buderus has also been producing steel boilers.

1958 - Due to the need for customer comfort, Buderus brought a new type of boiler, the Loganatherm, to the market. It was a combination of a cast iron boiler with an integrated hot water storage tank.

1962 - Buderus introduced the first wall-mounted heating body - Buderus Juno Heizblock, which was a revolution in heating at that time.

1977 - Buderus responded to the first oil crisis with low-temperature heating systems Ecomatic, which needed up to 15% less energy.

1981 - With the acquisition of the Dutch group Nefit, Buderus became a European market leader with even more efficient condensing technology.

1998 - 100 years after the ironworks Hirzenheim and Lollar received the first patent for the newly created sectioned boiler, the five-millionth cast iron boiler was produced in Lollar.

2002 - Since the beginning of solar technology, the Buderus brand has become a specialist in the integration of renewable energy in heating.

2003 - This year marked the transition from oil heating to compact, extremely quiet wall-mounted constructions in low-temperature and condensing versions.

2004 - At the annual general meeting of the Buderus company on May 13, it was decided to merge the activities in the field of heating technology of Robert Bosch GmbH and Buderus. The company BBT Thermotechnik GmbH is entered in the commercial register on August 2.

2005 - Buderus introduced the gas condensing boiler Logamax plus GB162s with a power of up to 100 kW and an exceptionally compact design. With the help of the offered accessories, it is possible to realize a 400 kW boiler cascade with low space requirements.

2008 - The company BBT Thermotechnik GmbH was renamed effective January 1 to Bosch Thermotechnik GmbH. The Buderus brand continues to maintain its separate identity in the brand portfolio.

2011 - The Buderus MyDevice application offers a completely new dimension of thermal comfort: with the MyDevice system, it is possible to conveniently control the heating system on the go - simply by swiping your finger across the smartphone display.

2014 - The revolutionary inverter technology of air-to-water heat pumps allows energy to be drawn from the air and converted into heat. It thus offers the possibility of using renewable energy sources for heating and the preparation of hot utility water.

2015 - Buderus introduces the new Titanium range, which combines the highest level of energy efficiency and system-integrated technology, in a new timeless design.

2021 - Buderus celebrates 290 years since its founding by J. W. Buderus.
