Product detailed description

Buderus Set for WB 1 VO

Buderus is part of the Bosch Thermotechnik group and has been a synonym for reliable and energy-efficient heating and hot water technology for decades. German manufacturing quality, an emphasis on precise connection dimensions, and long-term availability of spare parts and accessories are among the main reasons why Buderus boilers and system components are a popular choice among installers and investors throughout Europe.

The Set for WB 1 VO is genuine Buderus accessory for hydraulically separating the primary circuit of a wall-mounted condensing boiler (WB series) from secondary heating circuits. Wall-mounted boilers have a limited built-in circulation pump output and limited tolerance for the higher hydraulic resistance of a larger system — a hydraulic separator or heat exchanger, together with its own pump group, therefore separates the boiler's flow from the flow in the house's distribution system and enables reliable operation even with a larger or more complex system.

This variant includes a DN25 hydraulic separator and one HS25/6 pump group with the MM100 control module, which allows independent temperature control in the heating circuit according to a weather-compensated curve.

What's included in the set

  • DNA HYDRAULIC SEPARATOR TRANSVERSE DN25 (8718599384), 1 pc
  • DNA HS25/6 INSIDE WITH MM100 (7736601162), 1 pc
  • Hydraulic separator sensor 6.0 10K (7735502296), 1 pc
  • WMS 1 quick-mount group bracket (67900470), 1 pc

Purpose and number of heating circuits

Based on the composition of its components, the set is designed for connecting one independently controlled heating circuit (1 VO). The pump group (or the primary and mixing group) ensures circulation and temperature control in the heating circuit, the hydraulic separator/heat exchanger temperature sensor provides feedback to the boiler control, and the quick-mount group bracket (WMS) is used to attach the entire assembly to the wall or the piping system.

Installation

Connecting the hydraulic separator, pump groups, and sensors is a professional installation task that significantly affects the behavior of the entire heating system. Installation, electrical connection of sensors, and setting of control parameters must therefore be carried out by a certified installer or an authorized Buderus service technician, according to the project and installation manual.

Frequently Asked Questions

Why do I need a hydraulic separator or connecting set if I have a wall-mounted boiler?
Wall-mounted condensing boilers have limited flow capacity and pressure reserve of the circulation pump. If the heating system is larger, has more circuits, or has a different hydraulic resistance, it is necessary to separate the boiler's primary circuit from the secondary heating circuits — this is exactly what this set is for.

Does the set include the boiler itself?
No, the set is an accessory intended for hydraulic connection and separation of circuits; the Buderus WB series boiler must be ordered separately.

What is the difference between sets for 1 and 2 heating circuits?
The set for 1 VO includes one pump group and is intended for cases where separating one secondary circuit from the boiler is sufficient. The set for 2 VO includes two pump groups (primary and mixing) and the corresponding double bracket, allowing two separate heating circuits to be connected and independently controlled.

What is the difference between the S variant and the WT variant?
The S variant uses a classic flow-through DN25 hydraulic separator for hydraulic separation. The WT variant instead includes a plate heat exchanger (PWT 28), which also allows the medium in the primary and secondary circuits to be separated, for example in cases of different water quality requirements or greater distribution distances.

Who should install and connect the set?
Installation, sensor connection, and control settings must be carried out by a certified installer or an authorized Buderus service technician, in accordance with the project documentation and installation manual.

Does the set include a control system or control module?
The set includes a hydraulic separator/heat exchanger temperature sensor, which connects to the boiler's control system or a higher-level control unit. The controller itself (e.g. Logamatic) is included with the boiler or purchased separately depending on the specific configuration.

Warranty and service

The set's components are covered by the standard warranty period provided by the manufacturer Bosch Thermotechnik GmbH / Buderus and the seller in accordance with the applicable terms and conditions. To claim the full warranty on the boiler and accessories, we recommend having the installation and commissioning carried out by an authorized Buderus service partner and keeping the device's service book. If you have any questions about choosing the right set for your specific boiler type and output, please do not hesitate to contact us — we will be happy to help.

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.
